Season
The serviced season runs May 19 to September 30; off season, the campground is open for use with no fees and no services, until snow closes the gate. Once snow closes the gate and prevents parking at the campground, use the parking area for the Warm Springs Trailhead located just before the turnoff to Bonneville. Make sure to check road conditions before departing on your adventure. There is a trail from the parking area that intersects with Bonneville campground, or you can just walk down the road to the official entrance. Snowshoes or skies are recommended when snow is on the ground.

On-site developed park and hike-in sites are available seasonally at the official campground. Other National Forest developed and primitive camping sites/areas are also available nearby.
