Colby Pass Trail

Overview

If you’re linking the Roaring River/Cloud Canyon side of the park to Junction Meadow, Colby Pass is the direct, wild-feeling way to do it. Expect sweeping alpine views near the pass, a sparkling stop at Colby Lake, and broad meadow walking along the Roaring River. As a point-to-point crossing, the Colby Pass route runs about 17.2 miles between Junction Meadow and Roaring River. Many backpackers fold it into longer itineraries rather than tackling it as a single push.

Trail Experience

From the Cloud Canyon side, travel eases on the canyon floor with stretches of wet meadow and occasional boulder fields before you pick up more evident tread. Lower in the canyon you’ll encounter locked bear boxes and then meet the Colby Pass Trail south of Shorty’s Cabin; heading north leads through Big Wet Meadow and Cement Table Meadow in the Roaring River corridor. Near the crest, the pass is more “gap in the rocks” than broad saddle—expect rocky terrain and a high, exposed feel above treeline. The east side immediately below the pass uses well-built switchbacks on a steep mountainside.

Difficulty and Elevation

This is a strenuous high-country traverse. One documented day covered roughly 12 miles and 4,570 feet of descent from the pass to Roaring River (flip that for the climb if you’re heading up-canyon). On the west side, the on-trail climb to the pass is about 1,500 feet from where that party joined the route. Conditions can vary year to year; reports note occasional washouts/landslides and marshy sections in Cloud Canyon. Snow can linger at higher elevations, and you should be comfortable with alpine weather and footing.

Scenery, Geology, and Camping

The route strings together classic High Sierra elements: granite walls and glacially carved basins, a jewel-like Colby Lake just below the pass, and long, open meadows along the Roaring River. Parties have found acceptable camping on the flat floor of Cloud Canyon. Water is generally available from the lake and streams in the canyon, though you’ll weave around wet areas to keep feet dry.

Planning Tips

• This crossing is notably shorter than taking Elizabeth Pass between Junction Meadow and Roaring River (roughly 17 vs. ~38 miles). If time and energy matter, Colby is the efficient choice without shortchanging scenery.
• Expect variability: tread may be faint in places, cairns come and go, and damage from washouts/landslides can change the feel of the route. Confirm current conditions with the backcountry office before you commit.
• Overnight permits are required, and proper food storage is mandatory. Don’t count on backcountry bear boxes—they’re limited and sometimes locked—so carry your own approved bear-resistant container.

Best Time to Hike

Aim for the typical high-country window after seasonal snowmelt through early fall. You’ll spend meaningful time above treeline near the pass, so build in flexibility for wind and afternoon thunderstorms. The route sees far fewer people than busier High Sierra corridors, especially on the west side; weekdays are even quieter.
