This is Priest Lake’s natural granite water slide at the Lionhead Unit. It’s the most beautiful natural wonder. It’s a helluva drive and a bit of a hike, but boy did the kids (and the adults) love it. At the northernmost point of Priest Lake, just past where your GPS would take you to the Lionhead campground. GPS takes you to the group camp, but about a quarter mile past that is a large dirt turnout for the Lionhead camp, marked by a large post which used to have tiki heads.
