Campgrounds near Johnstown, Ohio
Johnstown sits in Licking County in central Ohio, roughly 25 miles northeast of Columbus. The area works well as an RV base because private campgrounds cluster along the corridors linking Columbus, Newark, and Sunbury, and Ohio State Parks with lakefront camping lie within a short drive.
Closest to town, Lazy River At Granville sits about 25 miles east of Columbus and offers full or partial hookup campsites that are big rig friendly. Farther north near Interstate 71, the Sunbury / Columbus North KOA Holiday operates on roughly 63 acres of mixed terrain in central Ohio, accommodating RVs up to 63 feet with full hookups. Additional private options in the area include Berkshire Lake Campground, Berkshire Campgrounds, and Rustic Knolls Campground.
For public land camping, Alum Creek State Park lies roughly 30 minutes west. Its 3,387-acre reservoir and 4,630 acres of gently rolling fields and woodlands provide a hub of recreational activity just minutes from Ohio's capital city, and it books through the state's reservation system.
Things to do near Johnstown
On-site activity varies widely by campground. Lazy River At Granville includes a pool area with a sprayground, a challenge course, a game room, a BMX track, picnic tables, fire circles, and grills, plus restrooms with hot showers and laundry facilities, and visitors can enjoy laser tag, zip lining, mini-golfing, gem mining, hiking, fishing, kayaking, and canoeing. The Sunbury / Columbus North KOA Holiday adds farm animals, playgrounds, gem mining, zip lines, a swimming pond, and inflatable bounce pads.
Off-site, the Alum Creek reservoir is the main draw. The lake is open to fishing, boating, ice fishing, ice boating, and swimming, and Ohio's largest inland beach sits on its west shore. Historic Granville, the Dawes Arboretum, and the National Heisey Glass Museum in Newark are all within a short drive, and the Columbus Zoo and Zoombezi Bay are reachable in under an hour.

Central Ohio has a four-season climate with a defined RV camping window. Most private parks in the Johnstown area open by early spring, and the Sunbury / Columbus North KOA Holiday operates on a seasonal calendar that runs from spring into late fall. Pool amenities usually track the summer holidays; at Sunbury, pool season runs Memorial Day Weekend to Labor Day Weekend.
Summer is peak season. Weekends near Memorial Day, the Fourth of July, and Labor Day fill first, and lakefront state park sites often sell out months in advance. Spring and early fall bring lighter crowds and mild temperatures well suited to hiking and biking; fall foliage typically peaks in mid to late October.
Winter camping is limited but not impossible. At Alum Creek, during the off-peak window from November through mid-April, only select areas are available, full hookup sites have sewer but no water, and shower buildings are closed. Some private parks, including Lazy River At Granville, remain open year-round with reduced services.
How to book
Ohio State Parks use a single centralized system. Reservations are required and may be made up to six months in advance, online or by phone, and there is no self-registration. At Alum Creek specifically, campsite reservations open in the morning six months ahead of the arrival date, and all sites can be reserved online. Popular summer weekends often clear out within minutes of the booking window opening.
Private parks handle their own reservations. The Sunbury / Columbus North KOA Holiday books through the KOA site or app, and Lazy River At Granville takes reservations by phone or through its website. For summer holiday weekends, book private parks six to eight weeks ahead; for state park lakefront sites, book at the six-month mark.
What to expect
Terrain is gently rolling farmland and hardwood forest, with reservoirs and small creeks providing most of the water recreation. RV sites at the major private parks in the area are generally level and accessible, with 20/30/50-amp service common. At the Sunbury / Columbus North KOA Holiday, back-in sites typically include city water, sewer, and 20/30/50 amp electric hookups.
State park sites are more rustic. Alum Creek's large campground features shaded sites for all types of camping, pets are welcome on all sites, and hundreds of electric campsites offer both wooded and sunny areas with some overlooking the lake. Expect firm quiet hours from 10 p.m. to 7 a.m., a two-vehicle-per-site limit, and leash rules for pets. Cell coverage is generally reliable across the region.
