San Luis Peak - Northeast Ridge
Climbing mountains is dangerous! Please read the Mountaineering Safety Page and make sure you have a map+compass and can use them effectively. A GPS or cell phone can be very helpful with navigation but you should still be able to use a map+compass in case your device stops working.
(WINTER) HOLD ON! If you don't have much high-elevation, winter climbing experience, be careful in your planning and take a partner. Even the "easy" 14ers (Quandary, Sherman, Grays & Torreys) can be deadly in winter.

The directions shown here assume you are coming from the north. If you are coming from the San Luis Valley area, drive north on Colorado 114 to Dome Lakes, turn left onto the 15GG road and follow the directions from Dome Lake, below:


Photo #1 and Photo #2 show the view of Stewart Creek from the trailhead ( 38.02465° N, -106.84124° W). Follow the excellent trail as it parallels Stewart Creek and enters the forest. After 2 miles on the trail, pass an old log building. After 3 miles, cross to the south side of Stewart Creek and later back to the north side. After 4 miles and near 12,000', leave the trees and reach a large clearing - Photo #3. Continue southwest and west on the trail as it approaches the upper basin - Photo #4, Photo #5 and Photo #6.

Near 12,300', turn southwest and cut through a large patch of willows to reach the creek. Cross it and continue southeast through more willows and begin climbing the broad slope ( 37.99528° N, -106.91658° W) below the Organ Mountain-San Luis saddle - Photo #6. From creek to the saddle, it's approximately 0.75 mile and 800' of elevation gain on mellow terrain - Photo #7, Photo #8 and Photo #9. Swing left near 12,800', ascend a couple of switchbacks and continue southwest to the 13,100-foot saddle ( 37.99129° N, -106.91936° W) - Photo #10 and Photo #11.

Hike west across the saddle and continue onto the left (south) side of a large point on San Luis' northeast ridge - Photo #11 and Photo #12. Traverse west toward the crest of the ridge - Photo #13, Photo #14 and Photo #15. Near 13,750', gain the northeast ridge ( 37.98911° N, -106.93085° W) and cross to the west side - Photo #16 and Photo #17. Follow the trail as it climbs through broken rock, regains the ridge (Photo #18) and climbs to the summit ( 37.986897° N, -106.931389° W) - Photo #19, Photo #20 and Photo #21.
