The area surrounding Green River Lake State Park is beautiful especially during the fall season. There are so many things to do like hike, rent a boat, camp, swim, putt putt golf, a marina with a restaurant, floating cabins, etc.
There is a visitors center off Lone Valley Rd which has alot of great pictures of the area and some amazing fish catches! There is also an overlook point that you can walk out to just beyond the visitors center.
Truly a remarkable place, if you have never seen it, do yourself a favor & come enjoy all it has to offer!
