Midway Pass - 8.0 Miles Round-Trip

Midway Creek Trail runs miles 8.7 miles from Lost Man Trailhead on Highway 82 to Hunter Flats in the Hunter - Fryingpan Wilderness. Midway Pass (11,841') is located 4 miles from the trailhead between Coleman Creek drainage (south) and Midway Creek drainage (north).

Midway Pass is a compelling and lightly used alternative to the Lost Man Loop, which leaves from the same trailhead and accesses Lost Man Lake and Independence Lake. The pass-approach features expansive alpine meadows with panoramic views across the Maroon Bells, Collegiate Peaks and Hunter-Fryingpan wilderness areas.

There are several accessible summits off the main trail, and these big open spaces are particularly good for seeing elk and mountain goats.

Note Midway Pass is not the highest point on the trail, and the divide it spans is fairly subtle. Additionally, some maps imply the distance is ~3.1 miles vs. 4.0 miles. This could be attributed to the highest point on the trail, not the actual point where drainages divide:

Follow signs left from the trailhead for Lost Man and Midway Creek. The trail arcs around a marshy area to the Midway Creek Trail (.35 miles : 10,620'), which splits left and climbs fast on methodical switchbacks.

It rises steadily to the Hunter - Fryingpan Wilderness Boundary (1.4 miles : 11,465') where grades moderate in a thinning forest. Small clearings on this leg offer good camping terrain.

The trail emerges from treeline (2.15 miles : 11,760') and crosses willow-covered meadows to the edge of a scenic pond framed by the Collegiate Peaks and Elk Mountains (2.7 miles : 11,970'). It steepens up a wide slope to the trail's high point (3.02 miles : 12,112'), a good turnaround point if limited by time or weather, and split-off point for reaching the 13,033' summit above.

The trail continues NW from the crest on a gradual descent with great views over Coleman Creek to Midway Pass (4.0 miles : 11,841').

This last mile can be faint, though cairns help and terrain naturally funnels you in the correct direction. The pass might not be obvious and is only marked by a large cairn and short wood pole, but newly-found views down Midway Creek will confirm your arrival.

Terrain remains fairly mild for some time down Midway Creek, and Midway Lake is only 1 mile away as the crow flies from Midway Pass.

"There are several large snowfields leading to Midway Pass. Most are packed and easy to cross, but some sections are still deep and you may see some postholing as snow softens throughout the day. Unseasonably hot weather is melting snow quickly."
