Driving Directions
From Lake City, drive about 2 miles south on Colorado 149 and turn right on County Road 30, toward Cinnamon Pass. From the start of the 30 road, it's over 20 miles to the trailhead. Stay right near 11.8 miles. After 12.5 miles the road becomes more rough, and between 13 and 14.5 miles it's a shelf road that hugs the south side of Sunshine Peak. Pass the Grizzly Gulch trailhead before 16 miles. Shortly after, the road gets more difficult and requires 4WD/AWD. Continue to a signed junction, at approx. 20 miles and turn left for American Basin. From here, it's 0.9 mile to the trailhead. After 0.2 mile, cross a stream. The remaining road becomes narrow and more difficult but there are some parking spots in this area. Continue higher to reach the trailhead at the end of the road.

Due to inaccuracies, do not use Google/Apple Maps directions to reach American Basin because it may suggest driving over Cinnamon Pass.
 Notes
Rough 2WD dirt (good clearance recommended) to 10,400' at the Silver Creek/Grizzly Gulch TH. Easy 4WD to 11,300' at the turn-off for American Basin. 4WD to 11,600' at the TH.

Trailhead Status Updates

Most Recent Update 6/20/2026:

Drove to the upper trailhead in a stock tacoma trdor, pretty rocky in a few areas that will make it a little tougher for any Subarus etc, but tacoma did fine. The trailhead was full when I got back with other tacomas, 4runners, jeeps, trucks, and SxS. Pictures are not of the worst spots. Afterwards I drove cinnamon pass down to Silverton.

Winter Access

Closed far below the Silver Creek/Grizzly Gulch TH.
