How is the drive between Tetilla Peak and Costilla Peak?
The 19.7 km track running from Bobcat Pass to Moreno Ranch is a high-mountain eiad that hits both Tetilla and Costilla peaks. The road is extremely rough, characterized by "tippy" off-camber sections and deep ruts carved by heavy snowmelt. You’ll face a vertical gain of 417 meters and a steep descent of 769 meters. The surface is unmaintained, consisting of loose stones and high centers that will snag the undercarriage of any vehicle without significant ground clearance.
Can I drive my vehicle on the road?
A 4x4 with low-range gearing is required.
What are the hazards on the Sangre de Cristo ridgeline?
The trail is narrow and exposed, with very few places to pass another vehicle. Meeting oncoming traffic on the steep ramps between the peaks often requires a dangerous reverse maneuver on loose, crumbling soil. At over 3,000 meters, thin air reduces engine performance, and summer thunderstorms can turn the dry track into a slick mud slide in minutes.
How remote is the drive?
There is no cell service in this remote corner of Northern New Mexico; a mechanical failure here means you are stranded miles from help in a high-consequence environment.
When is the road to the summits open?
Due to the extreme elevation, the road is typically buried under snow until at least July 4th. Even in mid-summer, heavy drifts can remain in shaded corners. During the spring thaw, the ground becomes a bottomless mud trap that is impassable for heavy vehicles.
When is the best time to drive the road?
The best window for a safe crossing is from late July through September. Always monitor the weather; if lightning or heavy rain starts while you are on the exposed ridge between Tetilla Peak and Costilla Peak, descend immediately to lower ground.
