What campers say
SYNTHESIZED · MODERATE SIGNAL
Sites
01 / 05
Dogwood and Elderberry loops are the ones to book for lake access.
These two loops give peek-through lake views and informal boat mooring, with the swim beach near Elderberry. Buckeye, Chinquapin, and the multi-use loop sit back in the trees with no water view.
Facilities
02 / 05
Flush toilets and potable water on site, but no showers anywhere in the campground.
Reviewers consistently flag the lack of showers; the nearest paid showers are about 15 minutes away at Camp Bushytail for around $5. Restroom upkeep is hit or miss, with occasional closures reported across multiple recent stays.
Water
03 / 05
Late-summer drawdown can leave the shoreline well below the campsites.
Trinity Lake is a working reservoir, and campers in drought years describe walking over exposed bank and downed wood to reach water. 2025 levels recovered, but the lake edge in August is rarely where it sits in June.
Vibe
04 / 05
Quiet from the highway, but daytime motorboat noise carries across the cove.
The campground sits two miles off Highway 3 so road noise is minimal, and sites are spaced under big trees. The sheltered arm is a favorite for waterskiing and wakeboarding, so expect engine noise on the water through the afternoon.
Wildlife & sky
05 / 05
Bear country with lockers at most sites, not all.
Black bears, bobcats, and mountain lions are documented in the area and food storage in approved containers is required. Campers report that a handful of sites lack a bear box, so plan to store food in the vehicle if yours is one of them.
