Tree Spring Trail 147
This is an easy to moderate, shaded one way trail in Cibola National Forest leading to the crest. It also crosses the 10k, Oso Corredor Trail 265, and Crest Trail.
You get to enjoy some great views to the north and east on the upper half of this trail. I recommend continuing west at the top for just 100-150 m to get a beautiful view of Albuquerque.
This trail is popular with mountain bikers, too, so keep an eye out, but they are usually courteous and respectful.
If you're into geocaching, this trail features several fairly easy caches.
Follow the Crest Road up; the trailhead is clearly marked shortly after the 5 mile point. Don't forget the $3.00 fee per day/vehicle. Parking can be difficult on the weekends because this trail is very popular, so come early.
Very pleasant trail, but it's 2 miles moderately uphill. Age 6+ should be fine up and back.
