Campgrounds and RV parks near Monroe, WI

The Sugar River State Trail runs about 24 miles of crushed limestone from New Glarus to Brodhead, linking Monticello and Albany along the way, and connects to the Badger State Trail that continues north toward Madison and south to the Illinois line. Both trails suit family biking, and the Jane Addams Trail continues south from the state line toward Freeport, Illinois. Water activity centers on the Sugar River. Tubing, canoeing, and kayaking are popular near Sweet Minnihaha Campground, which sits on the riverbank. Anglers target smallmouth bass in the river and largemouth bass, bluegill, crappie, walleye, and northern pike in Lake Le-Aqua-Na. In town, the National Historic Cheesemaking Center and the Green County courthouse square anchor Monroe, while New Glarus adds Swiss architecture, a brewery, and small museums.

Camping in the Monroe area is strongly seasonal. New Glarus Woods State Park is open year-round for day use, and the campground itself is listed as reservable through the state system, though services are limited outside the warm months and most visitors come between May and October. Lake Le-Aqua-Na's RV campground is technically open year-round, but the shower building with flush toilets and the trailer dump station operate only during the warm season, and the equestrian campground runs from April 15 to November 15, weather permitting. Summer weekends fill quickly, particularly around Memorial Day, Independence Day, and Labor Day. For Wisconsin state park sites, advance reservations booked before May 15 for stays between May 15 and October 31 require a two-night minimum, and a three-night minimum applies on holiday weekends. Fall brings hardwood color across the Driftless Region, cooler nights, and lighter campground occupancy midweek. Winter conditions are cold and snowy. Snowmobiling, ice fishing, sledding, and cross-country skiing are popular in the region, but drinking water, showers, and RV services are generally shut down until spring.

Expect a clear split between primitive state park camping and full-service private RV parks. New Glarus Woods provides drive-in and walk-to sites with fire rings, picnic tables, drinking-water pumps, and vault toilets. There are no showers and no sanitary dump station in the park, and only two designated sites (52 and the ADA-accessible 53) accept small trailers or pop-up campers, so larger rigs should look elsewhere. Lake Le-Aqua-Na has a much larger footprint with electric hookups at most sites, a trailer dump station, and a shower building open seasonally. Sweet Minnihaha and Crazy Horse offer hookups, shower houses, and family amenities. Pets are welcome at all listed campgrounds under leash rules. Cell coverage is generally reliable across the area, and grocery runs into Monroe or New Glarus are quick.
