Is it right for you?
Gilpin Peak stands on the south side of upper Yankee Boy Basin, across from Mount Sneffels. Newer survey data added 5 feet. A 4WD saves a lot of walking on the road.
From the trailhead at the vault toilet, you follow the Sneffels road and trail to a pond below a big rock glacier, contour southwest, and climb a steep couloir next to the ridge between Gilpin and Sneffels. From the top of the couloir, a short walk up the north ridge leads to the summit. It is Class 2+ with tough talus, and not a family hike.
The round trip is about 5.5 miles with 2,395 feet of gain. The ridge east to Mount Emma has Class 3 sections with some exposure; doing both peaks is about 6.95 miles with 3,295 feet of gain.

The steep couloir, either loose talus or snow.
Easy. The couloir sits just left of the Gilpin-Sneffels ridge.

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
Yankee Boy Basin - Mt. Sneffels
Take U.S. 550 to Ouray. About a quarter mile south of town, turn west onto County Road 361 toward Yankee Boy Basin. This is a dirt road. Keep right at the 4.6-mile mark. Around 5.2 miles the road runs along a shelf cut into the cliff, with rock hanging overhead. Stay right at the Imogene Pass turnoff near 5.9 miles.
At about 6.7 miles you reach the Governor Basin junction. Two-wheel-drive cars should park here; this adds about 1.75 miles round trip. High-clearance vehicles continue to the lower trailhead with an outhouse at about 7.5 miles and 11,350 feet. The figures on these pages start there. The last mile of road above the outhouse is very rough and only for high-clearance, short-wheelbase 4WD vehicles.
Camping inside Yankee Boy Basin is only allowed at the Thistledown and Angel Creek campgrounds lower on the road; check that they're open. Don't camp at the trailhead. Some flat spots near the toilet sit on old mining claims, and whether you can camp there is unclear.
