Campgrounds near Three Forks, Montana
Three Forks sits at the confluence of the Jefferson, Madison, and Gallatin Rivers in southwestern Montana, right off I-90 and roughly 30 miles west of Bozeman. The town works well as a base for RV travelers heading to Yellowstone, exploring blue-ribbon trout water, or breaking up a longer western road trip. Elevation runs around 4,000 feet, so nights stay cool even in summer.
Camping options range from full-hookup private RV parks in town to state-park campgrounds within a short drive. Three Forks Market RV Park and Three Forks KOA handle travelers who want power, water, and sewer close to services. Missouri Headwaters State Park, about four miles northeast of town, puts campers directly at the historic headwaters. Lewis and Clark Caverns State Park lies west along Montana Highway 2 and pairs camping with the state's best-known cave system. Cardwell General Store and Campground sits between the two along the Jefferson River corridor.
Most sites accommodate mid-size RVs, though a few in-town parks have tighter interior roads that big rigs should scout in advance.
Things to do near Three Forks
The headline attraction is Lewis and Clark Caverns State Park, which features one of the largest known limestone caverns in the Northwest, with cave access by guided tour only. Guided tours run May through September, with limited candlelight tours offered in December. The park also has a network of trails to hike or bike, plus a visitor center, café, and amphitheater programs.
At Missouri Headwaters State Park, visitors can walk interpretive trails to the point where the three rivers form the Missouri, fish, float, or paddle. River floating, fishing, picnicking, bicycling, hiking, and photography are all popular, and the site offers vault toilets, a group use area, RV dump station, grills, fire rings, picnic tables, and drinking water.
Other nearby draws include the Headwaters Heritage Museum in town, the Copper City mountain-biking trails, and blue-ribbon trout fishing on all three rivers.

The prime RV season around Three Forks runs late May through September. The growing season typically extends from the last frost in mid-to-late May through the first frost in late September, which lines up with when private parks and cave tours are fully operational. Three Forks KOA is open April 10 to October 20, and most in-town parks follow a similar spring-to-fall window.
State parks stay accessible for shoulder-season and winter trips, but services scale back. At Lewis and Clark Caverns, cave tours run May 1 through September 30, and campground showers, comfort stations, and water stations reopen as weather allows in spring. Winter travelers should use extra caution, be aware of potentially icy or snowy roads and trails, and check road conditions in advance.
July and August bring the warmest, driest weather and the heaviest bookings. Late spring can be wet, and shoulder months offer quieter campgrounds with cold overnight temperatures.

Bob made it super easy for us to rent a van. We have never done anything like this before and Bob made us feel comfortable and confident in our adventures. He was available for any questions or concerns and gave advice on where to find animals! We will definitely use Bob again!

How to book campgrounds near Three Forks
Montana state park sites are reserved through the state's ReserveAmerica portal at montanastateparks.reserveamerica.com, or by phone at 1-855-922-6768. Reservations at Missouri Headwaters State Park begin May 15, with six sites remaining first-come, first-served through summer. Campsites at Lewis and Clark Caverns State Park are reservable from mid-May through mid-September, and cave tour tickets are booked separately through the same system.
Private parks such as Three Forks KOA and Three Forks Market RV Park take direct reservations by phone or through their own websites. Book early for peak season, as campsites at Lewis and Clark Caverns are in high demand. For July and August weekends, plan on locking in state-park sites several weeks out. Weeknights and shoulder-season dates open up considerably.
What to expect on the ground
Expect open, high-plains scenery framed by distant mountain ranges, cool nights year-round, and quick weather changes. Three Forks KOA offers long, level RV sites with views toward the surrounding mountains. The Lewis and Clark Caverns campground is a large, family-friendly campground with a playground, bathhouse, and both electric and non-electric sites, plus cabins and a wall tent.
State park amenities are functional rather than luxurious. Lewis and Clark Caverns has a bathhouse with showers, flush toilets in season, vault toilets year-round, potable water, and a dump station. At Missouri Headwaters, campers may stay 7 days during a 30 day period, and mosquitoes can be heavy near the rivers in early summer.
Big rigs should confirm site length before booking. Cell service is generally reliable near I-90 and Three Forks itself.

Frequently asked questions about campgrounds near Three Forks, MT
How much does it cost to rent an RV in Three Forks, MT?
RV rental in Three Forks is generally more affordable than the gateway towns closer to Yellowstone. On RVezy, travel trailers in the area typically range from about $100 to $175 per night, while motorhomes commonly run $175 to $300 per night depending on class, age, and amenities, and many hosts offer weekly discounts. Late May and September are the sweet spot for a cheap RV rental Three Forks travelers love, since rates drop once Yellowstone's summer rush ends. For the best value, book a travel trailer with delivery to Three Forks KOA Journey or Missouri Headwaters State Park and skip the daily driving. Pro tip: filter by Instant Book to lock in confirmed pricing fast.
rvezy.com/rv-search?SearchAddress=Three%20Forks%2C%20MontanaDo I need a special license to rent an RV in Three Forks, MT?
A standard driver's license is all you need to rent an RV in Three Forks, Montana. No commercial driver's license (CDL) or RV endorsement is required, even for larger Class A motorhomes you might drive toward Yellowstone or Glacier. RVezy renters generally need to be 25 or older with a valid license, and your ID is verified securely through the platform during booking. Visiting from outside the US? Bring an International Driving Permit (IDP) from your home country along with your original license. Most first-time renters are surprised how simple it is before cruising Highway 287 with the Tobacco Root Mountains in the rearview.
help.rvezy.com/hc/en-us/articles/360039008774-Understanding-approved-driver-requirementsWhat protection or coverage is included with my RV rental in Three Forks?
Every RV rental in Three Forks booked through RVezy includes a renter protection plan plus 24/7 roadside assistance, so you can hit I-90 with real peace of mind. You choose your protection level at checkout (not the host), and each plan provides financial protection for covered damage to the RV during your trip. Combined with a thorough host walkthrough at pickup and support from the RVezy team, it is why so many first-time renters feel confident booking their first Montana RV trip near Lewis and Clark Caverns or Missouri Headwaters State Park.
help.rvezy.com/hc/en-us/articles/34008759079835-RVezy-renter-protection-plans-in-detailWhat if I need to cancel my Three Forks RV rental?
You can book with confidence. RVezy applies one consistent cancellation policy across the platform (hosts do not set their own), and the refund you receive depends on how far ahead of your trip you cancel. The full policy details are shown during checkout and in your RVezy dashboard, so there are no surprises. That flexibility matters around Three Forks, where weather on Bozeman Pass can shift quickly in spring and fall. If plans change, open your RVezy dashboard to start the cancellation, or message support for help.
help.rvezy.com/hc/en-us/articles/360037736674-Understanding-the-cancellation-policy-for-guestsCan I bring my dog on an RV trip from Three Forks?
Absolutely, pet-friendly RV rental Three Forks options are easy to find on RVezy. Just toggle the Pet-Friendly filter when browsing and you'll see plenty of hosts who welcome dogs (some even include pet bedding or bowls). Three Forks is a fantastic dog town: Missouri Headwaters State Park has miles of leashed-dog-friendly trails along the river, and the Headwaters Trail System connects right into downtown. Three Forks KOA Journey has a dedicated off-leash dog park, which is rare in the area. Pro tip: message the host before booking to confirm any pet fee and mention your dog's size, then pack a long lead because the riverbanks are too tempting to skip.
fwp.mt.gov/stateparks/missouri-headwatersCan the RV be delivered to my campground in Three Forks?
Yes, RV delivery Three Forks is one of the most popular options on RVezy, especially for first-time renters who don't want to drive a big rig out of the gate. Many local hosts will deliver, level, and set up the RV at Three Forks KOA Journey, Missouri Headwaters State Park, or even a private property along the Madison or Gallatin Rivers. They'll connect water, power, and sewer, then walk you through every system before handing over the keys. Use the Delivery filter to see hosts who offer it, then message them with your campsite number. It turns your motorhome rental Three Forks experience into a true vacation: arrive, unpack, relax.
fwp.mt.gov/stateparks/missouri-headwatersHow far can I drive on a Three Forks RV trip?
You've got incredible range from Three Forks, and many RVezy hosts offer generous mileage packages (some even RV rental with unlimited mileage). From Three Forks, Yellowstone's West Entrance is about 100 miles south (around 2 hours), Bozeman is just 30 miles east, Glacier National Park is roughly 280 miles northwest (5 hours), and Helena is 75 miles north. Big Sky and the Madison River fishing access points are under an hour away. Check each listing's daily mileage allowance and overage rate, then message the host if your route adds up to more (most are happy to bundle extra miles into a flat rate for longer trips toward Yellowstone or Glacier).
nps.gov/yell/planyourvisit/westentrance.htmWhere are the best campgrounds near Three Forks, MT?
You're spoiled for choice. The best campgrounds near Three Forks start with Missouri Headwaters State Park, where the Jefferson, Madison, and Gallatin Rivers meet to form the Missouri (full hookups available, open year-round). Three Forks KOA Journey on Highway 287 has full hookups, a pool, and a dog park, with mountain views in every direction. Lewis and Clark Caverns State Park, 20 miles west, offers electric and water hookups plus the famous cave tour. For something quieter, Cardwell General Store and Campground is a friendly 30-minute drive west. Bozeman Hot Springs Campground, 30 miles east, adds soaking pools to your RV camping Three Forks itinerary. Book Missouri Headwaters early, it fills fast in July.
fwp.mt.gov/stateparks/missouri-headwatersWhen is the best time to rent an RV in Three Forks?
Mid-June through mid-September is prime time for a Three Forks RV trip, with daytime highs in the 75 to 85 degree Fahrenheit range and cool 45 to 55 degree nights perfect for sleeping with the windows cracked. July and August are the busiest (and warmest), so book 2 to 3 months ahead. The insider play is late August through September: crowds thin, the cottonwoods along the Missouri turn gold, and fly fishing on the Madison hits its stride. May and early October work too, just expect chilly mornings and possible snow on Bozeman Pass. Winter rentals are available from select hosts, mainly four-season trailers with heated tanks for ice-fishing or Yellowstone snow trips.
weather.gov/byz/I've never rented an RV before. Will I be okay driving around Three Forks?
You'll do great, Three Forks is one of the friendliest places in Montana for first time renting an RV. The town sits at the junction of I-90 and Highway 287 with wide lanes, easy pull-throughs at the KOA, and minimal city traffic. Your host will give you a full walkthrough at pickup, covering propane, slide-outs, leveling, hookups, and dumping, plus they're a text away the entire trip. Stick to a Class C motorhome or mid-size travel trailer for your first time, and avoid driving the steep grade up to Lewis and Clark Caverns campground (park below and shuttle up). Pro tip: take a short loop on Highway 2 before your real trip to get comfortable.
mdt.mt.gov/travinfo/What happens if something goes wrong with the RV during my trip?
You are never stuck. Every RVezy booking includes 24/7 roadside assistance with the renter protection plan, covering things like flat tires, dead batteries, lockouts, and tows. If you have a mechanical issue along Highway 287 or near Norris Hot Springs, call the roadside number in your RVezy app and help is dispatched. Your host is also a quick text away and often knows the rig best for small fixes (like resetting a GFCI when the microwave will not power on). RVezy support is available before, during, and after your trip, and cell service is generally solid along I-90 and the Gallatin Valley.
help.rvezy.com/hc/en-us/articles/34008759079835-RVezy-renter-protection-plans-in-detailCan I take a Three Forks RV across state lines or into Canada?
Yes, most RVezy hosts in Three Forks happily allow interstate travel, which opens up an epic RV road trip from Three Forks through Wyoming (Yellowstone, Grand Teton), Idaho (Sawtooths), or up to Glacier and across to North Dakota. Cross-border trips into Canada are sometimes allowed depending on the host and protection coverage, so message the host directly from the listing if you're planning to drive to Banff or Waterton. Travel into Mexico is not permitted on RVezy rentals. Popular multi-state loops include Three Forks to Cody, Wyoming (3.5 hours) and Three Forks to Coeur d'Alene, Idaho (6 hours). Just confirm your route with your host so mileage and coverage are squared away.
cbp.gov/travel/us-citizens/know-before-you-goHow much should I budget for fuel on a Three Forks RV trip?
Fuel is one of your biggest line items, but Montana keeps it reasonable. Gas in Three Forks typically runs close to the national average, often a bit lower than gateway towns like West Yellowstone. Expect roughly 8 to 10 mpg for a Class A or large Class C, 12 to 16 mpg for a Class B campervan rental Three Forks travelers love, and 14 to 18 mpg combined (truck plus trailer) for travel trailers. A round trip to Yellowstone's West Entrance (about 200 miles) in a Class C runs roughly $70 to $100 in fuel. Pro tip: fill up in Three Forks or Belgrade before heading south, prices climb noticeably the closer you get to the park entrances.
eia.gov/petroleum/gasdiesel/How far in advance should I book a campground near Three Forks?
For July and August, book your campground 4 to 6 months ahead, especially Missouri Headwaters State Park, which fills the moment its reservation window opens. Montana State Parks open bookings 6 months in advance through their official reservation system at stateparks.mt.gov. Three Forks KOA Journey takes reservations directly through KOA.com and tends to have more last-minute availability than the state park. For September trips, 4 to 8 weeks ahead is usually enough. Pro tip: if you strike out at Missouri Headwaters, try Lewis and Clark Caverns State Park or one of the Madison River fishing access campgrounds, both excellent backups with real character.
fwp.mt.gov/stateparksWhat are the local driving conditions like around Three Forks?
Driving around Three Forks is genuinely easy, you've got flat valley floor with the Bridger, Tobacco Root, and Madison ranges as scenery, not obstacles. I-90 runs straight through with wide lanes and gentle grades. The one section to watch is Bozeman Pass (mile markers 313 to 319 on I-90), where wind gusts and winter snow can be intense. Check 511mt.net before you drive in shoulder seasons. Crosswinds across the open Gallatin Valley can push high-profile rigs, so reduce speed in gusts. Watch for wildlife (deer, antelope) at dawn and dusk, especially on Highway 287 toward Ennis. Otherwise, you're driving wide-open Montana skies with very little traffic. It's a dream for new RV drivers.
mdt.mt.gov/travinfo/roadreport.aspxWhere can I dump tanks and fill fresh water near Three Forks?
You've got easy options. Missouri Headwaters State Park has a dump station and potable water fill available to registered campers (and sometimes non-campers for a small fee). Three Forks KOA Journey offers full hookups at every site plus a dump station for transient use. Bozeman Hot Springs Campground, 30 miles east, has a dump station and is open year-round. Most local gas stations along I-90 (including the Town Pump in Belgrade) have potable water. For free public dump stations, check sanidumps.com or rvdumps.com before you roll. Pro tip: dump and refill before leaving for Yellowstone, services inside the park book up fast and cost more.
fwp.mt.gov/stateparks/missouri-headwatersWhat amenities can I expect inside my Three Forks RV rental?
Most RVs you'll rent in Three Forks come fully equipped for a comfortable Montana trip: a real bed (queen or king in most Class Cs and trailers), a kitchen with fridge, stove, microwave, and sink, an indoor bathroom with shower and toilet, plus a dining area that converts to extra sleeping. Air conditioning, propane heat, and seatbelted seating for travel are standard. Many hosts add a generator (great for boondocking near the Madison River), a flat-screen TV, and even Starlink or hotspot Wi-Fi. Each listing shows exactly what's included, plus the sleeps count, so you can match the rig to your group. Pro tip: confirm bedding and kitchenware are included, some hosts toss these in free, others charge a small add-on.
fwp.mt.gov/stateparks/missouri-headwatersWhat add-ons and pickup options are available with my rental?
Three Forks hosts on RVezy offer a wide range of add-ons: camp chairs and tables, bedding and towel packages, kitchen kits, bikes, paddleboards (great for the Missouri Headwaters), fishing gear, generators, and sometimes Starlink. Delivery and setup is one of the most popular options, with typical local delivery fees commonly $50 to $200 depending on distance. Pickup is usually at the host's home in or near Three Forks, Manhattan, or Belgrade, with a full orientation included. Mileage policies vary by listing, often around 100 to 150 free miles per day with overage charges, and some hosts offer flat-rate or unlimited mileage for longer Yellowstone or Glacier trips. Filter by what matters most and message hosts to customize.
rvezy.com/rv-search?SearchAddress=Three%20Forks%2C%20MontanaHow does payment and the security deposit work on RVezy?
Payment is simple and secure. You pay through RVezy at booking (never in cash to the host), and the platform holds funds so both sides are protected. A separate refundable security deposit is placed on your card before pickup, with the amount set by the host and shown on the listing. As long as the RV is returned in the same condition (clean, with tanks handled per the listing, and no damage), the hold is released after your trip ends. Pro tip: take date-stamped walkaround photos at pickup and dropoff to keep your RV rental in Three Forks stress-free.
help.rvezy.com/hc/en-us/articles/360038106214-How-the-security-deposit-worksHow do I prep an RV rental for cold weather in Three Forks?
Winter and shoulder-season camping around Three Forks is absolutely doable, you just want the right rig. Look for listings labeled four-season or with heated holding tanks, enclosed underbellies, and dual-pane windows (search filters help here). Nighttime temps from late October through April can drop into the teens or single digits Fahrenheit, and Bozeman Pass occasionally closes during storms. Plan to camp where you have shore power (Bozeman Hot Springs Campground and Three Forks KOA Journey both stay open year-round with electric hookups). Bring extra propane, a heated water hose, and tank antifreeze. Your host will walk you through winterization at pickup. Pro tip: a cold-weather Yellowstone trip with steaming geysers and bison in snow is unforgettable.
