Trailhead Directions

I-25 east to Tijeras exit, north on NM 14, west on Crest Road to PARK (0.0 mi) at the Tree Spring trailhead. On the way, leave a shuttle vehicle at the west end of the Doc Long Picnic Grounds (BILL SPR TH). Put a Golden Age Passport on dashboard of each vehicle.

Actual Hike

This trail starts near the outhouses just west of the parking (PARK) area. The trail is well-marked and easy to follow. This is a hike through a lush woodland of mixed conifer, oak, and aspen trees. There are just enough aspen to make it a worthwhile fall color hike. All along this well used trail there are many wildflowers in the spring and summer months. Hike uphill until you see the junction with 0so Corredor Tr 265 (TREE-OSO at 0.3 mi). The trail is undulating with a total ascent of less than 250 ft and ends at its juncture with Faulty Tr 195 (OSO-FAULTY)(3.0 mi). Head east on Faulty Tr which descends steeply until it meets with Bill Spring Tr (FAULTY-BILL) (3.3. mi). Follow this trail to TANK (3.9 mi) and the shuttle location at BILL SPR TH. Have lunch at the picnic tables at Doc Long’s.


Tree Spring trail is well used and weathered and has many tripping hazards such as exposed tree roots, pointy rocks and the like, so hikers should mind their footing while they enjoy the scenery. Tree Spring Trail #147 is outside of the Sandia Wilderness Area, so you may encounter bicycles. Oso Corredor means “Running Bear”. Except for short rocky Faulty Trail, the footing is very good and elevation gain is very gradual. There are Abert’s squirrels in the Doc Long Picnic Ground that are quite large and tame and are remarkable for their grey and white coloring.
