Permit Reservations:
Reservations for wilderness permits are available for approximately two-thirds of each daily entry quota (except the Lakes Trail – toward Emerald and Pear Lakes –which cannot be reserved). Permit reservations are highly recommended for large groups, holiday weekends, and late summer weekends.
A Wilderness reservation confirmation letter is not a wilderness permit and cannot be used for overnight travel. Your confirmation letter will include details of where to pick up your permit. Permits are issued during normal operating hours by trailhead rangers who provide important area information. There are no “night drops.” You can pick up your wilderness permit on the afternoon prior to your hike date (after 1:00 pm) or by 9:00 am on the morning of your entry date. If you need to pick up your permit later than 9:00 am on the morning of your entry date, notify the Wilderness Office at (559) 565-3766 or seki_wilderness_office@nps.gov. If you do not make arrangements for a late pickup, your reservation may be cancelled at 9:00 am and your spots given to people waiting for walk-up permits.
The Wilderness Office receives a high volume of phone calls and e-mails. Please review this trip planner and our website prior to calling or sending an email about trip planning.

Walk-up/First-come, First-serve Permits:
Approximately one-third of each quota is available on a first-come, first-serve basis at the station closest to the trailhead starting at 1 pm the day before departure, or on the day of departure.

So I should probably make a permit reservation which I would then pick up when I get there, is that correct?
