Hidden Lake, sometimes called Underground Lake, is a small, natural lake nestled in a cave on the Best Friends Animal Sanctuary. Even though this lake is on private property, the sanctuary allows you to visit. There is a narrow sandy road all the way to the lake, but we decided that it was a little too sandy for us to try in our van. We knew if we had to pull over to pass someone on the narrow road, that we’d likely spin our tires into that sand and need help getting out. We wouldn’t recommend a car on this road. But we do recommend visiting Hidden Lake in Kanab.
