How long openings last
Half of the openings the scanner caught on Happy Isles to Past LYV (Donohue Pass eligible) were gone within 45 minutes.
Measured across 18 openings that did not reopen, as of August 2026.
Each figure comes from our own scans, comparing when an opening appeared with when it was gone. Permits we cannot measure precisely enough are left out rather than estimated.

How cancellation tracking works
Sold out almost never means gone. People cancel JMT Yosemite trips for weather, injuries, and schedule changes, and those dates go straight back to the booking system without any announcement.
PermitSnag checks JMT Yosemite availability around the clock, compares every scan against the last known state, and alerts watchers only when the open dates actually change. No refresh-tab-and-pray, no false alarms from unchanged listings.
JMT Yosemite availability questions
How do I get a JMT Yosemite permit after it sells out?
Cancellations. Booked JMT Yosemite permits that get cancelled return to the reservation system, usually with no announcement. PermitSnag scans continuously and alerts you the moment a date you want opens up.
How often do JMT Yosemite permits become available?
In the recent tracking window our scanner detected 737 availability changes for JMT Yosemite and sent 228 alerts to watchers in the last 30 days. Cancellations cluster around fee deadlines and weather changes.
How fast are JMT Yosemite availability alerts?
Paid plans are scanned about every minute and alerts go out within seconds of a detected opening, by push notification, SMS, and email. Free accounts are scanned hourly.
Can I still get a JMT Yosemite permit if I lost the lottery?
Usually yes. Winners cancel or skip payment deadlines, and those dates return to the booking system. Tracking JMT Yosemite for cancellations is the standard fallback after a lottery loss.
