The American Spring Loop is a nice singletrack loop between Water and Valles Canyons. The lower part of the loop is relatively easy and flowy, but the upper part is a little more technical with large embedded rocks and ledges.

The Guaje Canyon Trail departs from the Pajarito Mountain Ski Area and ascends up a gulch to the ridge line. Although it's not overly steep, it is pretty steadily uphill the entire way so be sure to pace yourself! This trail is also popular with hikers so be on the lookout for them as you ride. In the wintertime you can cross country ski and snowshoe up this trail (and others that cross and intersect it). It is groomed and well-maintained by the ski area for your use.

During the summer you can take the Aspen Lift (the central lift) to the top of the mountain and ride down one of the many mountain bike trails in the area. This is a great way to get some challenging downhill miles in without having to ride back up!

The Pajarito Canyon Trail runs along a river in Pajarito Canyon. This scenic trail is often completed as a loop with the Nail Trail (the junction with this trail is more or less where the canyon ends), but you can actually take it to the top of Pajarito Mountain, which is home to a popular local ski area.
