San Jacinto Deer Springs Trailhead permit
Idyllwild approach to San Jacinto....

Most popular access via the aerial tramway.
Long Valley sits inside Mount San Jacinto State Park, and California State Parks issues its wilderness permits off any booking system. "Permits are required for hiking and backcountry camping at Mount San Jacinto State Park and Wilderness." Camping ones are "$5.00 per person and subject to availability, as each backcountry campground has a limited number of designated campsites", and you get one by post — a completed application, a cheque and a stamped self-addressed envelope to the park in Idyllwild — or over the counter at Park Headquarters, up to eight weeks ahead. The Long Valley Ranger Station at the top of the tramway sells them too, but "Cash or check only. Same-day permits only." Nothing is sold online, so there is no calendar to watch.

No. There is nothing to book. California State Parks issues Mount San Jacinto wilderness permits on paper: "Permits are required for hiking and backcountry camping at Mount San Jacinto State Park and Wilderness", and you get one at Park Headquarters in Idyllwild, at the Long Valley Ranger Station at the top of the tramway, or by post.
The park publishes one figure: "These permits are $5.00 per person and subject to availability, as each backcountry campground has a limited number of designated campsites to preserve the wilderness." Day-use wilderness permits are free. The tramway ticket is separate and is not a permit.
Eight weeks. "Wilderness camping permits may be acquired up to 8 weeks before your desired camping date." Post the application, a cheque and a stamped self-addressed envelope — the park says outright that "we do not process permit applications without a SASE". At the Long Valley Ranger Station it is cash or cheque, same day only.
