217 Highway TT, Danville, MO 63361-5509, United States
History-curious campers and paddlers get the most from this place. The Graham Cave interpretive trail is short and genuinely interesting, the boat ramp puts you on the Loutre in minutes, and fall weekends are quieter than summer with better trail and river conditions.
Amenity facts here are thin and conflicting, so confirm showers and hookups before booking. I-70 noise bothers light sleepers on most sites, and a handful of reviews describe an unwelcoming atmosphere toward campers who aren't part of the local cultural mainstream, which is worth

The reservoir has a surface area of 2,250 acres and 14 miles of shoreline. The Park includes boating, camping, picnic facilities, fishing, hiking, and serves as a major family destination for many in the west central valley.

Fall offers the best combination of mild weather, vivid glade and riverbank color, and excellent hiking conditions. Daytime highs typically range from the mid-50s to upper-60s°F (45–70°F), with crisp mornings. Trails and the open glades are at their most scenic in September–October, while river levels are often lower and calmer for paddling or fishing. Crowds are generally lighter than summer weekend peaks, making it easier to enjoy the cave, interpretive exhibits, and quiet riverside campsites. Spring brings pleasant hiking weather and wildflowers. Summer means lush foliage, more traffic, bugs, and muddy trails after rain. The park's small size and heavy tree cover make it a popular shoulder-season or overnight stopover rather than a winter destination.
Peak season with warm weather, perfect for water activities. Book early.
