Get an email when a timed-entry or backcountry permit opens
Popular trails, canyons and park entrances limit each day to a fixed number of permits, and those permits often sell out the moment a release window opens. Dates come back when people cancel or when a later release is published. Sold Out Alert watches the permit page for the dates and group size you need and emails you when one shows as available.
What you can watch
- A day-use entry permit for any Saturday in August
- An overnight backcountry permit for two people in September
- A river or canyon permit on the weekend of the 12th
- A timed entry slot before 10am on a weekday
- Any permit for a group of four in the next release window
How it works
Paste the link to the permit availability page and say which dates, group size and permit type would work for you.
Sold Out Alert reads the page once, shows you what it will check, and tells you whether the page can be tracked before you start.
When a permit that matches shows as available, you get an email with the link. You apply or book yourself.
We alert you by email; you book it yourself. Sold Out Alert never logs into your accounts or buys anything for you. Plans start at $9 a month with a 7-day free trial.
Questions
- Will Sold Out Alert get me a permit?
- No. It cannot reserve, hold or enter a lottery for you, and it is not an official service or affiliated with any park agency. It emails you when the page shows availability and you book it yourself. Permits that return are usually claimed fast.
- Does it work for permit lotteries?
- A lottery is decided by the agency after an entry period, so there is nothing to watch while it runs. It can help after the draw, when leftover or cancelled permits are posted for sale.
- Can I watch a date range instead of one day?
- Yes. Say something like any weekend in the second half of July, with your group size, and the watch looks for any date that fits rather than a single day.
- What if the permit page cannot be watched?
- Pages behind a login cannot be watched, and some permit sites block automated checking or draw their calendars in ways that cannot be read reliably. Sold Out Alert checks the page before you start and tells you whether it can be tracked. Checks run from every 5 minutes on the lowest plan to every 1 minute on the highest.
