Know before you go!

ACCESS: The Tin Cup Trailhead at Pettit Lake is very popular with limited parking. Be ready with a back-up plan if you cannot find a parking spot. Park only in designated sites. Please do not park off the side of the road in the sagebrush or other vegetation, it destroys the delicate alpine habitat. There is some overflow parking at the Tin Cup Horse Trailhead.

STAY ON THE TRAIL

Please don’t cut switchbacks! It causes erosion, destroys vegetation, and ruins the trail. This trail has switchbacks, please use them.

PACK IT IN; PACK IT OUT

Most of our trailheads do not have trash facilities. Please be prepared to pack out all of your trash from the trail and trailhead.

GO BEFORE YOU GO

Burry human waste 6-8 inches deep and pack out all toilet paper and wipes. There is a restroom at Pettit/Tin Cup Trailhead.
