Location: Near San Ysidro, approximately 50 miles northwest of Albuquerque.

Distance: ~8.4 miles (loop).

Difficulty: Intermediate to Advanced—rocky sections, steep climbs, and technical descents.

Surface: Predominantly gypsum and sandstone, creating a slick, hard-packed surface that can be slippery when wet. This loop trail takes riders over rolling gypsum hills with challenging inclines and fast-flowing descents. The ridge section offers exceptional panoramic views of the Rio Puerco Valley, with exposed sections that demand skill and confidence.

Technical Challenges: Several tough switchbacks, a few short but steep climbs, and technical drop-offs.

Trail Markings: Well-marked but can be confusing in areas—a GPS track is recommended.

Nearby Amenities: No facilities—bring plenty of water and supplies. The nearest services are in San Ysidro or Bernalillo.

Geological Wonder: The landscape is composed of gypsum, a soft mineral that reflects sunlight, giving the look of an alien world.

Movie-Ready Scenery: The otherworldly terrain has drawn interest from photographers and filmmakers.

Historical Context: The terrain was shaped by ancient inland seas, leaving behind rolling hills and exposed ridgelines.

Best Time to Ride: Spring and fall offer ideal temperatures; summer can be dangerously hot.

What to Bring:

Helmet, gloves, and protective gear (due to jagged terrain).

At least 2L of water per person.

Spare tube and repair kit (sharp gypsum can cause punctures).

Directions: From Albuquerque, take US-550 northwest for ~45 miles, turn south onto Cabezon Road, then onto White Ridge Trailhead Road (dirt)—allow 1h 15m travel time.
