Overview

About Lake Fork Trail #2 to Sundance Pass

Why go

  • A cascading creek and several named lake destinations break up the climb
  • The full route reaches a high alpine pass

Heads up

  • The pass is about a 19-mile round trip with 3,800 feet of elevation change
  • Snow often delays full pass access until mid-July
Lake Fork Trail #2 is a 19-mile out-and-back from Lake Fork Road to Sundance Pass, following the cascading Lake Fork of Rock Creek past a series of lakes to a saddle just over 11,000 feet. The Forest Service lists the pass 9.5 miles from the trailhead, with about 3,800 feet of elevation change. This is a hard, high-altitude day rather than a casual lake walk; allow about 12 hours for the full return and start early enough to turn around with time to spare.

Before you go

Parking

From US 212, turn west onto Lake Fork Road (Forest Road 2346) and drive 1.9 miles to Lake Fork Trailhead 2. The Forest Service lists ample parking, room for horse trailers, and a vault toilet. The separate Lower Lake Fork Trail #2A starts from the highway and adds about 2 miles to the #2 junction.

Safety

A strenuous high-altitude outing: about 19 miles round trip, 3,800 feet of elevation change, and a pass just over 11,000 feet. Snow commonly delays full access to Sundance Pass until mid-July. Check current conditions and turn around at an earlier lake if the timing or conditions do not suit your group.

Trail guide

Hiking Lake Fork Trail #2 to Sundance Pass

Follow the creekThe route starts with a rolling, gentle climb that follows the river grade.

The route starts with a rolling, gentle climb that follows the river grade. Broadwater Lake is 3.75 miles in and makes a natural shorter destination: the round trip there is about 7.5 miles. The path is a standard ground-surface trail and shares the corridor with horseback riders. Expect the sound of the creek to be part of the walk for much of this lower section.

The lake spursThe Lost Lake junction is 5 miles from the trailhead; a 0.3-mile side trail reaches the lake.

The Lost Lake junction is 5 miles from the trailhead; a 0.3-mile side trail reaches the lake. Keyser Brown Lake junction is at 6 miles, with a 0.6-mile side trail. These are useful turnarounds if you want a substantial hike without committing to the pass. September Morn Lake is 8 miles in on the main route, so it is a major destination in its own right, though still a long return to the road.

The climb to Sundance PassPast the Keyser Brown junction, the climb steepens on its way to the pass.

Past the Keyser Brown junction, the climb steepens on its way to the pass. The route reaches September Morn Lake before the final high-country stretch to Sundance Pass at 9.5 miles. At the saddle, the trail crosses into the West Fork drainage; if you are not doing a point-to-point trip with transport, turn around and retrace Lake Fork. Snow commonly delays full access to the pass until mid-July, so check current conditions before setting out. For a photo, wait for calm water at September Morn Lake and frame the reflected mountain wall with a little shoreline in front.

Getting there and making the day workFrom US 212, turn west onto Lake Fork Road (Forest Road 2346) and continue 1.

From US 212, turn west onto Lake Fork Road (Forest Road 2346) and continue 1.9 miles to Lake Fork Trailhead 2. The Forest Service describes ample parking, room for horse trailers, and a vault toilet. It lists hiking and horseback riding as allowed uses. No food service or other on-route facilities were found, so carry provisions for a long wilderness day. The separate Lower Lake Fork Trail #2A starts nearer the highway and adds about two miles to the #2 junction; use the Lake Fork Road trailhead for the route described here.
