How to Get a Alaska Basin Permit

The lake basin on the Tetons' west side that everyone books through Grand Teton - and that is not in Grand Teton National Park at all.

Check Alaska Basin permit availability

No nightly fee. Recreation.gov's Grand Teton permit states plainly that there is no nightly fee charged for this site, because it is not park service land.

About Alaska Basin

Alaska Basin is in the Jedediah Smith Wilderness on the Caribou-Targhee National Forest, not in Grand Teton National Park. Both agencies say so. The Park Service's route page states that the Teton Crest Trail intersects into Caribou-Targhee National Forest at Fox Creek Pass and Alaska Basin, and that since it is Forest Service land, different regulations apply. Recreation.gov's Grand Teton permit carries a division named USFS - Alaska Basin whose description reads: this is not a park service managed camping zone, it is a National Forest Service Wilderness Area along the Teton Crest Trail where people can camp if they wish, and there is no nightly fee charged for this site. So the practical answer is: a Grand Teton backcountry permit is not required for Alaska Basin. The zone exists in the park's system only so that a continuous Teton Crest Trail itinerary can account for that night, and no nightly fee attaches to it. If your whole trip is in Alaska Basin, you need nothing from the national park. What the Forest Service publishes about the basin is short. It calls it a beautiful high elevation basin that holds a few lakes with amazing views, a favourite for hikers who want to do the up-and-over into Grand Teton National Park, gives Sunset Lake at 9,500 feet, and lists its restrictions as, in full, wilderness regulations apply. For the Jedediah Smith Wilderness as a whole it publishes 123,451 acres on the west slope of the Teton Range, and a food-storage line: bears roam Jedediah Smith, so store food in bear-proof containers or hang it high. What we deliberately do not state here: whether a Forest Service permit or registration is required for the Jedediah Smith Wilderness, what the group-size limit is, and what camping setbacks apply. Those figures could not be read from a Forest Service page - fs.usda.gov returns 403 to automated requests and the archived page's entire restrictions field says only that wilderness regulations apply. Call the Caribou-Targhee Supervisor's Office at 208-557-5900 before you plan around any specific rule.

Alaska Basin is the most commonly misfiled camp in the Teton Range. It appears as a selectable zone inside the Grand Teton backcountry permit, which makes it look like park land. It is not. The Park Service says so directly: the Teton Crest Trail intersects into Bridger-Teton National Forest at Teton Pass and Caribou-Targhee National Forest at Fox Creek Pass and Alaska Basin, and since it is Forest Service land, different regulations apply. Recreation.gov's own division for it is blunter still - this is not a park service managed camping zone, it is a National Forest Service Wilderness Area along the Teton Crest Trail where people can camp if they wish, and there is no nightly fee charged for this site.

The Experience

Open shelves of limestone and small lakes below the back side of the Grand, with the range's west slope falling away toward Idaho. Quieter than anything on the park side of the crest, and with a different set of rules the moment you cross the boundary.

Most people reach Alaska Basin from the park side, over Hurricane Pass out of the South Fork of Cascade Canyon, or from the Idaho side out of Teton Canyon. The Forest Service describes it as a beautiful high elevation basin that holds a few lakes with amazing views and a favourite for hikers wanting to do the up-and-over into Grand Teton National Park, and gives Sunset Lake at 9,500 feet. The basin sits in the Jedediah Smith Wilderness, which the agency describes as spanning 123,451 acres on the west slope of the Teton Range - jagged limestone peaks, deep canyons and sweeping views.

What that means practically: a Grand Teton backcountry permit is not required for Alaska Basin itself. The zone exists inside the park's permit system so that a continuous Teton Crest itinerary can account for a night spent there, and it carries no $7 nightly fee. A trip entirely within Alaska Basin needs nothing from Grand Teton.

Permit Requirements

This is Forest Service wilderness, not national park land, and Forest Service wilderness regulations apply

A Grand Teton backcountry permit is not required for Alaska Basin, and no nightly fee is charged for it

Store food in bear-proof containers or hang it high - the Forest Service's own instruction for the Jedediah Smith Wilderness

The Forest Service's published restriction for the basin is, in full, that wilderness regulations apply. Call the Caribou-Targhee Supervisor's Office at 208-557-5900 for the specifics before you rely on any of them

Gear & Preparation

Required Gear

  • A bear-proof container or a way to hang food high
  • An ice axe if you are crossing a Teton Crest divide before late July - the park's guidance covers Hurricane, Mt. Meek and Fox Creek Passes as well as the divides
  • Water treatment
  • Wind and rain layers for open ground above 9,000 feet

Recommended Gear

  • Trekking poles for the climb over Hurricane Pass
  • Sun protection - the basin is open limestone with almost no shade
  • A shelter that stands up to afternoon thunderstorms
  • Warm layers; 9,500 feet gets cold after sunset even in August

Hazards & Safety

Snow on the Teton Crest passes into late July, which the park says can require an ice axe

Afternoon thunderstorms on open ground with no shelter

Bears throughout the Jedediah Smith Wilderness

A rules gap: the Forest Service publishes almost nothing about this basin beyond wilderness regulations apply, so plan conservatively and call ahead

Best Time to Visit

Late July through September, set by snow on the passes rather than by any permit season. The Park Service's guidance for the crest's divides and passes is that safe travel can require an ice axe and knowledge of its use as late as August.

Pro Tips

1

If your whole trip is Alaska Basin, you do not need to touch the Grand Teton permit system at all.

2

If you are walking the Teton Crest, book the Alaska Basin night inside the Grand Teton permit anyway - that is what the zone is there for, and it costs nothing per night.

3

You will already be carrying an IGBC canister for the park side of the crest. Keep using it here; the Forest Service rule is looser but the bears are the same ones.

4

Call 208-557-5900 for Jedediah Smith Wilderness rules rather than assuming the park's rules carry over. The Park Service's own wording is that different regulations apply.

5

Time the trip by the passes, not the calendar. Hurricane, Mt. Meek and Fox Creek can all hold snow into late July.
