Campgrounds and RV parks near Grayville, IL

Outdoor activity centers on the Wabash River corridor. Beall Woods State Park draws visitors interested in one of the few remaining tracts of virgin timber east of the Mississippi River, with trees 120 feet tall and more than 3 feet in diameter. Five scenic trails wind through the park, including the 1-mile Tuliptree Trail and the 1.25-mile White Oak Trail, both easy walks; the 1.75-mile Ridgeway Trail can be combined with the White Oak Trail for a 3-mile loop, and the short Sweet Gum Trail follows a creek to a rocky cliff. The park's lake holds bluegill, largemouth bass, catfish, and other panfish and is a quiet spot for shore fishing. At Harmonie State Park Campground, families use trails for walking, biking, and mountain biking, and there is a boat ramp on the Wabash. Nearby Historic New Harmony preserves two utopian communities from the early 1800s and is administered as a program of the University of Southern Indiana.

Spring brings wildflowers and green-up along the Wabash bottomlands, but it is also the wettest stretch of the year. May is typically the rainiest month, and river levels can rise quickly after storms, occasionally affecting low-lying picnic and boat-ramp areas. Trails at Beall Woods and Harmonie can be muddy well into May. Summer is peak camping season. Humidity is high, thunderstorms are common in the afternoon, and mosquitoes are active near timbered and river-adjacent sites. Weekends at Harmonie State Park Campground fill early, so reservations should be locked in well in advance for holidays and summer Saturdays. The KOA runs a full activity calendar during this period. Fall brings the most comfortable conditions: cooler nights, lower humidity, and hardwood color through October. Deer hunting by archery is legal within Beall Woods to reduce the effects of an overabundance of white-tailed deer, with firearm hunting limited to the statewide firearm season, so campers should check park notices before choosing a fall date. Winter camping is possible; the Grayville / I-64 KOA Holiday is open year round, while state park facilities and water service are reduced.

Expect a mix of full-service and rustic. The Grayville / I-64 KOA Holiday has 68 RV sites, 10 cabins, a restaurant and bar, playground, miniature golf, and a mechanical shooting gallery; sites are level, nearly 100 feet long, with 50/30/20 amp service and water and sewer full hookups. Interstate access is easy off exit 130. Harmonie State Park Campground has around 200 family sites with electrical hookups and modern restrooms, along with a youth-group area in a more primitive setting. Only a few sites offer full hookups, but water spigots are distributed through the loops, and each site has a fire ring and picnic table. A camp store, dump station, and bathhouses serve the loops. Beall Woods is a rustic stop: pit toilets, drinking water, dump station, no showers, and no electric hookups. Cell coverage in the state parks can be spotty, so download maps and reservation confirmations before arrival.
