Is it right for you?
East Trinity is the eastern of the three Trinity summits in the Grenadier Range, deep in the Weminuche Wilderness. On its own it may be the easiest of the three, but it is usually climbed at the end of the Trinity traverse.
From a high camp in Vestal Creek you climb West Trinity, cross to Trinity Peak (Class 4), and descend a shallow couloir south of the ridge to the saddle with East Trinity. You then climb its west ridge, mostly on the south side, to Class 3 rock near the top. The way down is the northeast ridge at Class 2+ and a tundra walk back to camp.
The loop from the upper camp is about 4.85 miles with 4,650 feet of gain. The upper camp sits in the last open trees beside Vestal Creek at 11,760 feet, about 9 miles from the Molas trailhead: 6.5 miles to the beaver ponds on Elk Creek, then about 2.5 miles up the steep, unmaintained Vestal Creek trail. Marmots here are known for wrecking gear and food. From the Molas trailhead the whole trip is about 22.85 miles and 7,550 feet.
Plan of the day
Leave the upper Vestal Creek camp by 5 a.m.
Be on West Trinity by 9:30 a.m.; skip the traverse if storms are building.
Class 4 on the traverse to Trinity Peak; steep, loose Class 3 below East Trinity.
Moderate. In the descent couloir, climb over into a second couloir when the first veers right.
Elk Creek, the beaver ponds and Vestal Creek. Little or none up high. Filter it.

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
Molas Pass - Elk Park
From Silverton, drive south on US 550 toward Molas Pass. About 5.3 miles from the Silverton turnoff, and a little past the Molas Lake road, turn left into the Molas trailhead lot. From Durango, cross Coal Bank and Molas passes; the lot is about 1.1 miles past the top of Molas Pass on the right. The dirt lot is fine for any car but can be muddy and have potholes.
You can also ride the Durango and Silverton train to the Elk Park stop and skip the descent from Molas Pass; check the railroad's current schedule and stops. Camping is available near Molas Lake and Little Molas Lake. Protect your food and gear in Vestal Creek: the marmots there are known to chew through tents, packs and anything salty.
