Lake Cascade State Park's Poison Creek Campground sits along the eastern shore of Lake Cascade, managed by Idaho Parks and Recreation and open from late May through the end of December. Sites are spacious and paved, with full hookups including electric, water, and sewer connections for RVs up to 50 feet. The campground also has WiFi, showers, and a dump station, making it a practical base for longer stays.
The terrain is open, which means lake views are unobstructed from many sites. Campers get water on one side and mountain sightlines on the other, a combination that multiple reviewers have singled out as a reason to return. A small marina area gives access to the lake, and kayaks, canoes, and boats are available to rent on-site. Cell coverage is reportedly solid, with one camper noting five bars of 5G on AT&T. Shade is limited, so sites exposed to afternoon sun may be a factor to weigh in summer months.
The facilities earn consistent praise. "Showers and facilities clean," notes Phillip C., who has visited twice. Fireplace areas arrive raked and tidy. Camp hosts are present and attentive, which reviewers describe as helpful but firm about rules. Reservations are strongly recommended for weekends. Donnelly, about four miles north, covers any forgotten supplies. Nearby, West Mountain Campground — Lake Cascade State Park and Buttercup Campground — Lake Cascade State Park provide additional options within the park for groups or overflow. Senior discounts are available, so it's worth asking at check-in.

22 sites with full hook-ups. Group Shelter can be reserved through the park. Shower house, flush toilets when available and vault restrooms. Boat Ramp with handling docks. Boat Ramp and parking lot open year round. Tamarack Resort has a concession to rent motorized and non-motorized boats.
