About
Overview
Rainbow Point Campground is located next to scenic Lake Cascade in west central Idaho. It is near the town of Donnelly, at an elevation of 4,850 feet. Boating, fishing, swimming and hiking are popular activities in this scenic region.
Note: During the 2022 season, thinning work will be conducted in neighboring Amanita campground to reduce the risk associated with root rot and subsequent hazard trees.
Recreation
Lake Cascade offers excellent opportunities for boating, water skiing, canoeing, windsurfing and sailing. Anglers enjoy casting for rainbow trout, coho salmon, smallmouth bass and perch. A boat ramp is located within the campground. Many hiking and biking trails are in the area as well.
Facilities
This small campground offers single-family campsites. Each is equipped with a picnic table, campfire ring and grill. Some sites have lake views and shoreline access.
Vault toilets, drinking water and trash collection are provided, but electricity is not available at the campground. Roads and parking spurs within the facility are gravel.
Natural Features
The campground is situated on the west shore of the lake, among a mixed-growth conifer forest that towers over the campground. Summer wildflowers are abundant.
A wide variety of wildlife makes its home around the lake. Waterfowl and songbirds can also be seen in the area, as well as pelicans and bald eagles.
