I know I am out of shape but this trail was not in any way easy for anyone that I went with! It is easy in the sense that you don't have to climb or anything like that but it is so long! We could barely make it back to our car our legs and feet were burning. It was so cool though I would totally do it again and would recommend it to anyone but if you go all the way down to the dam and back just know it is a long long journey! Haha. The tunnels are super awesome to see and go through. We could hear bats inside the tunnels and we saw some rams on the hillside. Super cool trail!
