Ride in a wilderness area and get in trouble with the rangers. Really, try it . . . I was attempting the flater lake trail, but wound up at the top of Tounge mountain. The easiest thing to do would be to follow the trail markers and look at a topo map. Just be polite and try not to take anyone's kids out.
Most families usually hike only a mile and then decide it is toomuch exercise anyhow.
By law bikes are permitted on all trails within the Adirondack Park, so hopefully this summer I will try a lot more. Some are probably unrideable though, others are suppossed to be worth the trip and a good ride. Very steep in some parts with a lot of roots and large rocks, and a few fallen trees, but a lot of hikers use the trail, and is easy to follow. The view is worth it at the top by the leanto.
