About Rainbow Point
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.

FAQ
How do I get a reservation at Rainbow Point?
Campsite Sniper's current snapshot shows none of the 98 tracked site-nights open for online reservation at Rainbow Point. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Sep 18, 2026 15:19 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.

7 of the 7 sites that support RV analysis have a recorded maximum of 35 ft or more; the longest recorded is 45 ft.
Does Rainbow Point have online availability right now?
