Mt. Whitney Permit
Cancellation Alerts
Mt. Whitney — the highest summit in the lower 48 — is one of the most sought-after permits on recreation.gov. The lottery fills instantly, but day-use and overnight permits get cancelled all season. Tarn watches around the clock and alerts you by email or Telegram the instant a Whitney permit opens, so you can grab it before anyone else.

Day use or overnight, your exact dates
Track the permit you need — a summit day-hike or an overnight — for the dates you want:
The quota season runs May through early November, and summer weekends are the hardest to land. But cancellations open spots right up to your trip date — whichever permit and dates you’re after, Tarn watches for the opening and alerts you the moment one appears.
