Access to lower/popular elevation trailheads will be in high demand, wilderness permits have been gone months ago, you will have to try to secure a first come, first served permit, and for areas beyond, you will also need to possess winter camping experience, exceptional navigation skills, and understand the risks/dangers of snow/ice travel and high flow creek crossings.
Yosemite NP regulation for first come, first served permits:
Wilderness permits are available during business hours at any permit issuing station beginning at 11 am the day before the beginning of your wilderness trip. Priority for permits for a particular trailhead is given to the closest permit issuing station, though it is possible to obtain a permit for any trailhead at any permit issuing station. This mainly affects the most popular trailheads that fill up quickly each morning, such as Little Yosemite Valley trailheads, Lyell Canyon, Cathedral Lakes, among others.
First-come, first-served procedure for all wilderness permit stations (approximately May through October): Unreserved permits are available on a first-come, first-served basis beginning at 11 am on the day before the intended entry date. All reservations (same day and next day) and same-day unreserved permits may still be picked up when the wilderness center opens for the day.
Though popular trailheads may fill up, there is always space available on other trailheads in the park. From November through April, wilderness permits are available without a reservation.
Inyo NF regulations for first come, first served permits:
Walk in permits must be requested in person at the visitor centers. During the quota season (May 1 to November 1) walk in permits cannot be issued more than one day before the entry date. Permits are issued for same day entry or for next day entry; you must enter on the date stated.
- Walk-in permits are subject to space available* at the time the permit request is processed.

*The amount of space available for walk-in permits may vary. For all trails except Mt Whitney, 40% of the quota space is saved for walk-in permit requests. In addition, space from any reservations that did not fully book, cancelations, group size reductions, and reservations that are not confirmed or picked up (No Show) will be made available for walk-in requests. Some specific trails are identified as non-quota and are only limited by maximum group size.
