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.

Colorado 13er · South Side from Stone Man Pass

Overview

McHenrys Peak rises above the head of Glacier Gorge and is known as the hardest non-technical 13er in Rocky Mountain National Park. From Black Lake you climb to Stone Man Pass between Chiefs Head and McHenrys, then follow a faint, winding path up the south side, through boulders and small cliff bands, to the summit ridge.

It is Class 3 in spots and gets steeper and rockier the higher you go. The top is surprisingly big and flat.

The round trip is about 13 miles with about 4,500 feet of gain. Mileage and gain are our estimates. Many people pair it with Chiefs Head from a backcountry campsite (permit required).

Plan of the day

Start by

By 4:30 a.m.

Turnaround

Be at Stone Man Pass by 10 a.m.

Crux

Steep, rocky Class 3 scrambling on the upper south side.

Route-finding

Moderate. From Stone Man Pass, the path contours west, then climbs. It splits and fades; stay well below the ridge until you reach the upper south ridge.

Water

Glacier Creek and the lakes. Filter it.

Less traffic, less margin

This describes the route on a dry summer day. Most 13ers see few people, so there may be no one along behind you. Check recent conditions the week you go, carry a map, tell someone your plan, and turn around when the day tells you to.
