We did the Lenawee Mountain mountain bike ride Monday. It involved riding the Argentine North Fork Trail to Black Mountain Lodge, riding the Summer Road to The Summit, riding down the Lenawee Trail to Peru Creek Road, and riding down valley to our house.. The Lenawee Trail is beautiful and heads Southeast off The Summit outside of the ski area. Much of it is over my head (yes, I walked a lot), but we still had a great time. The views are incredible. As a bike ride it is pretty hard core. For your general hiker, capable of walking 6 miles and climbing a couple of thousand feet, it is outstanding.
