How cancellation tracking works
Sold out almost never means gone. People cancel Halfmoon trips for weather, injuries, and schedule changes, and those dates go straight back to the booking system without any announcement.
PermitSnag checks Halfmoon 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.
Halfmoon availability questions
How do I get a Halfmoon permit after it sells out?
Cancellations. Booked Halfmoon 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 Halfmoon permits become available?
Cancellation timing is unpredictable, which is why continuous monitoring matters. Spots tend to open around payment deadlines and in the days right before trips, when plans fall through.
How fast are Halfmoon 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.
