Other than camping and fishing, hiking is the main recreational activity whether it is this simple trail along the back side of the lake or...
this trail from the upper picnic area to the top of the ridge or...
a trail like this to points beyond.
Here's a good look up the length of the lake.
On clearer days this view point not far from the entrance to the campground looks south towards the City of Rocks.
