Forty-two kilometers of trail and one very cold lake

Three backcountry huts, a ridge that tops out at 3,610 meters, and a campground under the pines. Here's what you need before you head up.

Trailhead

Pick your trail at the board

Every trail starts at the main lot. Distances are one way unless the trail is a loop, and the shape on the post tells you how hard it gets.

Check in before you go up

Overnight trips need a backcountry permit. Rangers post the weather, fire danger, and trail closures on the board by the door every morning.

Park rules

01

Pack it in, pack it out

There are no trash cans past the trailhead. Whatever you carry up comes back down with you.
02

Stay on the trail

The alpine meadows take decades to recover from a single shortcut.
03

Let wildlife stay wild

Keep at least 25 meters from elk and 100 meters from bears. Store food in the lockers.
04

Fires in rings only

Campfires are allowed in the steel rings at Pine Hollow. Check the fire danger board first.
05

Quiet hours, 10 PM to 6 AM

Sound carries across the lake. So do the stars, if you're quiet enough to notice.

See you on the ridge.
