The National Trail, from Telegraph Pass to the final descent.
National is best known for the eastern descent, from the Buena Vista parking lot to the Pima Canyon lot, leaving the western 2/3 of the epic trail lightly traveled. While I lived there, I always wanted to ride the rest of the trail, but never got around to doing the whole thing.
We weren't planning to make the west part of National a part of the trip, but glad we did; it's a true epic.
