Chama - Antonito - Tres Piedras Loop (3 Days)


Chama Train - Eric Russell Photo

North of Chama

The Chama - Antonito - Tres Piedras Loop is a very scenic, moderate ride through the forests in northern New Mexico, mostly on lightly traveled highways. This ride goes through large aspen forests that in the fall (September) change from green to vivid yellow, oranges and reds that are hard to beat. Be prepared for cold (freezing) mornings and warm afternoons this time of year.

The route from Chama to Mogote climbs Cumbres Pass (10,015) and La Manga Pass (10,230') which are only moderate climbs. You can even race the train up to Cumbres Pass from Chama. The route follows the scenic Conejos River to Mogote, west of Antonito, CO. The route then turns south on US285 to Tres Piedras passing San Antonio Mountain where there is often antelope grazing. The route then turns east climbing to terrific views of the Brazos Cliffs before a swift descent to Tierra Amarilla. The ride north to Chama completes the loop. Take water and food along and be prepared for storms.

Roadways: Most of the roadways have light traffic except for US285 from Antonito to Tres Piedras. US285 from Antonito to Tres Piedras has moderate fast traffic but has shoulders except the last 8 miles to Tres Piedras. US84 from Tres Piedras to Tierra Amarilla has light traffic and is very scenic, an ideal touring roadway. US64 from Tierra Amarilla to Chama has moderate traffic at times but has shoulders most of the way. NM17 & CO17 have light traffic.

Getting There: Start in Chama, however, since it is a loop the ride can start at any point on the loop. There are a number of motels and B&B's where you can start and finish at.

Distance: 140 Miles, 8,800 Ft. Elevation Gain (3 days). This is a moderate ride. The climbs and descents of Cumbres and La Manga Passes are moderate, nothing too extreme, see the elevation profiles below.


  • A two day option is to ride from Chama to Mogote, spend the night, then return to Chama. This misses the scenic section on US64, though. 40 Miles each way 2500' climbing Mogote to Chama, just one steep stretch going up La Manga Pass but in itself is a great ride.
  • Ride from Chama to the summit La Managa Pass and back. This a ~42 mile ride depending on where you turn around but a great ride. The descent is real pretty.

Notes: Chama has a grocery store on the south end of town. There is a restaurant at the east side of La Manga Pass after the descent. The route comes near Antonito, CO but does not enter the town. There are motels and grocery stores in Antonito. There is a cafe in Tres Piedras but that is about all. There are no supplies from the Running Elk to Tierra Amarilla on US64.
