Solo and couple campers looking for tent or RV sites will find nothing here, since Section 3 is group and cabin bookings only. Those who want direct lake views should look at Section 4 instead, and anyone sensitive to chiggers should pack serious repellent before hitting the wood

Fall offers the best combination of comfortable weather and scenery. Daytime highs typically range from the low 50s to mid-70s°F with crisp nights, making hiking and biking under the oak and hickory canopy very pleasant. Lake water often stays warm enough for boating and late-season swimming early in the season, while fishing is excellent as fish feed in cooling waters. Crowds drop after Labor Day so you get quieter trails, easier beach access, and better chances for peaceful wildlife viewing. Summer brings hot, humid days better suited for lake activities than long hikes; campers report significant heat that discourages midday hiking. The campground welcomes visitors April through October, with some facilities operating on limited schedules in the off-season.
Peak season with warm weather, perfect for water activities. Book early.
