No wonder solitude is rated 1 today, as the Hill of Life and the upper falls were packed with people and their dogs on this sunny Sat. after a very cold start of the new year. Introduced the hill to my 13 yrs old and she did the way back up with some minor complaints :-). On the way down we looked for a geocache off main trail which was fun. Try the trails that go off to the right. Great single trek for bikes!
