Great campground only 45 minutes from Boise. I used an RV site and it was easy to access. Having cell service and a garbage service were added pluses!

Nice CG with nice spacing between sites. Paved road in and paved pads a plus. Other than sparse vegetation, a very good place to camp. Road in has a steep sharp curve, but not an issue if you take your time.

Spacious site. It was quiet and very relaxing. Enjoyed that the campsite is away from Highway 21. We would stay here again.

This is a beautiful campground with very clean bathroom/pit toilets. It was peaceful and had plenty of walking and hiking access points. It was well worth a 30 mile off route stop over.
