      From the town of Crestone, from the second stop sign, turn right on Galena. Follow the gravel road 1.5 miles to a location where 2WD vehicles can park. 4WD vehicles can proceed another .75 mile to the trailhead parking. South Crestone Lake trail #860 heads out straight ahead. Willow Lake trail # 865 veers to the right and crosses the creek.


      Primitive sites are available along FR949 once you get on Forest land. Be careful about private property through here, especially on the south side of the road. Some limited car camping at the trailhead.

    • From Willow Lake Trail TH via Willow Lake

      Last visited this trail in 2002. At that time, there was no official bridge crossing Crestone Creek at the TH. We were able to get across on fallen logs, but in higher runoff, you may have to wade. After crossing the creek from the TH, the trail climbs east up an open hill, then begins a series of switchbacks through forest, crosses a ridge and then contours up valley, well above Willow Creek. As the trail approaches a large waterfall it climbs on switchbacks more steeply, heading in a more southerly direction, crosses Willow Creek below the waterfall on a log bridge, and climbs steeply up an area of rubble as it turns back to the east and begins to level out as it approaches the beautiful Willow Lake. A scenic waterfall plunges into the far eastern end of the lake. Overall, this is a moderately strenuous backpack. Trail is maintained and easy to follow except where it crosses back over Willow Creek above the waterfall and a little before the lake.

      Note: Expect high weekend traffic at the trailhead because this is an access for climbing Challenger and Kit Carson and has become very popular.


      Main camping on the approach is at Willow Lake. In keeping with FS camping policies, campsites are located away from the lake and along the northern side, somewhat elevated above the lake. Also, there are sites well before reaching the lake on the hike in. Watch for FS signs designating where to camp. Camping locations may have changed due to FS regulations since our last visit in 2002.

      Note: This area has become very popular with the 14er bagging crowd. Competition for campsites at Willow Lake on weekends may result.

    Route Description

    Year Climbed: 1995

    From Willow Lake, walk around the north side of the lake on the trail access into the upper Willow Creek basin. From the NE shore, you can proceed up directly toward the summit by heading up mixed tundra/rock slopes that steepen and become more of a tundra/rock/scree mix as you gain elevation. There is a shallow couloir that can be utilized or a parallel rib of stable rock embedded in tundra. You may encounter one short rock-scramble section. In early season, there may be snow, so ice axe is handy. Return by the same route, or proceed over to Mt. Adams or UN13,541, both along connecting ridges.

    Alternate: From Willow Lake, head directly north through trees for a brief while and enter a drainage that comes in from the north and that leads into a basin that curves east and below the foot of Mt. Adams. From the basin, head ESE toward the summit of UN13,580 on moderate slopes.
