Campgrounds and RV parks near Bunker Hill, IL

Fishing is the main draw at the nearby state parks. Beaver Dam State Park centers on a 59-acre lake stocked with channel catfish, bluegill, crappie, largemouth bass, and redear sunfish. The 750-acre park also offers hiking and biking trails, an archery range, picnicking, and wildlife viewing in oak and hickory woods. At Horseshoe Lake State Park, anglers target largemouth bass, crappie, bluegill, catfish, and carp on a large natural oxbow lake, and the park's 2,960 acres draw birders looking for herons, egrets, and migratory waterfowl. A boat ramp provides access for motors up to 50 horsepower, though swimming is not permitted. Note that the campground and its access road have been closed for causeway work, so confirm status with the site before visiting. Day trips from Bunker Hill reach the Gateway Arch, Cahokia Mounds, and the Lewis and Clark State Historic Site along the Mississippi River.

The prime RV season runs from late spring through early fall. May through October brings warm days, active fishing, and full campground programming. Spring can be wet, with April and May among the rainiest months in this part of Illinois, so RVers should expect thunderstorms and occasional flooding on low-lying river bottoms. Summer is hot and humid, with July highs in the mid-80s and heavy afternoon storms possible. This is peak family camping season, and reservable sites at state parks fill quickly on weekends and holidays. Fall brings cooler nights, lower humidity, and strong color in the oak-hickory woods through late October. Seasonal closures matter for trip planning. Horseshoe Lake State Park's campground is open from May 1 through September 30, with a maximum stay of seven days in any 30-day period, and it does not take reservations for camping.
