Climbing the Southwest Ridge

From Saguache or US 50, take Highway 114 and turn onto NN14 (BLM 3083), then follow long graded dirt roads about 30 miles to the Stewart Creek Trailhead; a crossover or high clearance vehicle is best. Hike the Stewart Creek trail toward San Luis Peak, then leave it for Stewart's Class 2 southwest ridge on tundra and talus. The mileage is long and the area is remote with little cell coverage. Many parties backpack in to add Baldy Alto and San Luis. Start early for afternoon storms. Carry plenty of water.
