Caribou Pass - 6.8 Miles Round-Trip
Caribou Pass (11,851') is located 3.4 miles from Junco Lake Trailhead along the Caribou Lake cirque rim between the Arapaho Creek and Meadow Creek drainages. It spans broad, sloping meadows just over a precipitous drop into the lake basin with exceptional views down each valley, and along the Continental Divide.
The Caribou Pass Trail runs moderately to the Columbine Lake Trail split, then steepens incrementally through treeline to the pass. It continues around the cirque and along the Divide to Lake Dorothy (12,061') and Arapaho Pass (11,906').
The segment between Caribou Pass and Dorothy is stunning, but runs across a few narrow catwalks etched into the upper cirque rim that can be treacherous with snow and uncomfortable for some. Lake Dorothy is .75 miles from the pass and well worth the effort if weather and conditions allow:
The trail begins on a rocky jeep road that steepens to an unmarked fork; keep left (1.0 mile : 10,350'). It rises to a large meadow at the Indian Peaks Wilderness Boundary, past which dogs must be leashed (1.28 miles : 10,420').
The trail arcs around the meadow, veers left at a re-vegetation sign (1.55 miles) and switchbacks up to the Columbine Lake Trail split (1.95 miles : 10,570').
The Caribou Pass Trail veers left and steepens to the base of meadows at 2.15 miles (10,775'), 2.6 miles (11,070') and 2.78 miles (11,210'). It climbs steadily through treeline to a rickety wooden post marking Caribou Pass (3.4 miles : 11,809').
The true pass is located a few steps ahead along the rim (11,851') over Caribou Lake. Rim edges and cornices can be unstable - keep a safe distance and pets and children under control.
The trail continues SE up to a switchback (3.55 miles : 11,850'), which swings back to and just inside the cirque rim. Here it narrows on a path etched high into the cirque wall and rises to open tundra along the Continental Divide and Lake Dorothy (4.15 miles : 12,061').
A minor scramble at approximately 3.7 miles can be unsettling for some, especially with snow or ice. Use good judgment and avoid slide-prone rocks.
