We rented bikes when we at the WL for a couple hours, it was a lot of fun. We biked over to the campground and went to the petting zoo(it's free). My DD also went on a pony ride for, I think it was, a dollar. Then rode around the campfround to explore. I forget how much it cost but it was pretty cheap, we rented 2 bicycles, 1 with a child seat.
It was a fun afternoon.
