453 openings caught in the last 90 days. Historical openings; nights may be on different sites and may no longer be available.
A full campground can open up again
Campsite alerts watch for availability after you have searched. When another camper cancels, changes their dates, or the park releases more sites, an alert can help you find the opening without repeatedly refreshing the reservation page.
Set the dates you can actually travel and choose whether you need every night or would accept part of your stay. Check the full reservation before booking: available nights may be spread across different campsites.

Questions about campsite alerts
Are campsite alerts free?
Yes. The free plan includes 3 trips at a time, up to 6 campgrounds each, checks about every 10 minutes, text, email, or both on each alert, and no card is required. A trip is the campgrounds you pick in one park for the same dates. Paid plans with about 5-minute checks and more trips are planned for after beta: Standard ($10/month) and Plus ($20/month), plus a $12 Trip Pass.
Can I get campsite alerts by text, email, or push notification?
Choose text, email, or both on each alert and verify each destination. You can also enable browser push notifications for all your alerts in Account. Push requires a supported browser and notification permission.
Which campgrounds can I watch?
Search for your park or campground above. OpenCampsite supports locations across the US and Canada, including campgrounds on Recreation.gov, ReserveCalifornia, ReserveAmerica, Parks Canada, Ontario Parks, and BC Parks. Coverage varies by location; the search shows whether you can create an alert.
How quickly will I hear about a campsite cancellation?
OpenCampsite checks booking calendars about every 10 minutes, day and night, adjusting for demand, and sends a notification when a check finds a matching opening. Checks are periodic, so a cancellation can happen between checks. Delivery time also depends on your email, mobile carrier, or browser.
Does an alert reserve the campsite for me?
No. An alert does not book or hold a campsite. Follow the booking link, confirm availability for your full stay and equipment, and pay the park's normal reservation fees on its official booking site. Another camper may book the opening before you reach it.
Be ready when an opening appears
An alert does not hold a campsite. Have your reservation account and trip details ready so you can check the site's rules and finish booking on the official website.
Watching several suitable campgrounds or a wider date range gives you more possible matches. Keep a backup plan: an opening may be booked before you reach it.
