Castle Creek Trailhead

Elk Mountains

Road Difficulty

4 Moderate 4WD, good clearance

Driving Directions

Take Castle Creek from the roundabout just west of the center of Aspen. Drive 12.5 miles (paved) to the Castle Creek trailhead. To the right, Forest Road (FR) 102 continues all all the way to 12,800'. Good-clearance passenger cars can drive about 1 mile up this road to reach the dispersed camp sites along the road. If you want to shorten your hike by parking higher, you must have a 4WD vehicle with good clearance. From the lower trailhead parking area, proceed to a river crossing, at 1.3 miles. In spring and early summer, this crossing is a challenge for some 4WD vehicles. At 3 miles, reach the Pearl Pass junction and stay right on the Castle Creek 102 road. If you drove up this far, there are a few parking spots near the junction. The road gets worse as it ascends into Montezuma Basin all the way to 12,800'.

Notes

2WD paved access to 9,750' from the north via Castle Creek road out of Aspen. Rough, Rocky 2WD access to approx. 9,900' by turning right on the dirt road at the end of Castle Creek road. High-clearance 4WD from the river crossing and higher.

Most Recent Update 8/29/2026:

Got to 12,800' at the end of the road in a Jeep Wrangler. There weren't any particular difficulties along the way though it was slow and bumpy all the way. A few parts are steep and loose but never needed to shift to 4L. It took about 52 minutes to drive the dirt portion from the pavement. There was one truck there before us and a Rivian (R2?) when we returned for what that's worth....
