Is it right for you?
Window Peak is an easy summit on the volcanic ridge just south of The Window, a famous notch south of Rio Grande Pyramid. Newer survey data left it with too little rise above its saddle to count as a ranked peak, but the view of the Needle and Grenadier mountains is superb. It pairs well with UN 13,022.
Most people backpack in on the Weminuche Creek trail (Trail 818), a fairly easy hike of about 5.1 miles and 1,325 feet of gain, and camp just north of Weminuche Pass at about 10,650 feet, near a side stream coming in from the west. Many of the trees there are now dead, but good flat sites remain. This is wild country; bears have been seen near camp, so store food well. From camp, the Skyline Trail or the Continental Divide Trail leads to the area just northeast of The Window. You walk up grassy tundra to The Window, then go south along the east side of the ridge and up to the top. It's Class 1.
From the trailhead, the trip with UN 13,022 is about 21 miles with about 4,125 feet of gain. From the camp, it's about 10.8 miles and 2,800 feet, and Window Peak alone is about 5.4 miles one way.

Afternoon storm risk is the line that matters. Everything else is comfort. In summer, plan to be off the ridge before the build-up starts, not as it starts. Forecast for the summit point, adjusted for its elevation · data from Open-Meteo.
Getting there
Thirtymile Campground
From Highway 149, turn west onto Forest Road 520. The turn is about 20.5 miles west of Creede, or about 32 miles south of Lake City over Slumgullion and Spring Creek passes. The road starts paved, then becomes graded dirt. Stay on the main road toward Rio Grande Reservoir; most junctions are signed. Thirtymile Campground is about 10.8 miles from the highway.
The road is fine for passenger cars. Drive south across the river on a bridge into the campground. Hiker parking is on the north side of the campground road. Walk south across the campground loop to the trailhead for the Weminuche Creek trail, which shares a start with the Squaw Creek trail. Thirtymile and nearby River Hill are fee campgrounds that can be reserved.
