That “fully booked” campground? Sites open up every day.
Popular campgrounds book up the minute reservations open. Then plans change, people cancel, and sites come back one night at a time. Nabbi watches 5,000+ campgrounds and emails you when your nights open, for your group size.

How campsite alerts work
- Pick a campground and your nights. Choose exact dates, or a range like “any two nights in July.”
- Tell us your group. Nights in a row and number of guests, so we only alert you about sites that actually fit.
- We check the availability grid. Every 10 minutes (2 with Priority) we look at every site for your nights.
- You get the site and the link. The email names the open site and dates and links straight to the booking page.
Tips from the campground trenches
- Be flexible by a night. Single nights open far more often than full weekends. Grab one and watch for the next.
- Watch more than one campground. Add every campground in the area to one trip, and your odds go up fast.
- Weekdays and shoulder season open up much more often than summer Saturdays.
- Cancellations spike before the deadline. Many people cancel shortly before fees go up. Keep alerts running right up to your trip.
- Read the site details (tent pad, RV length, walk-in) before you book. A fast checkout is no good if your rig doesn’t fit.
Campsite questions
When do campgrounds first go on sale?
It depends on the campground. Many Recreation.gov campgrounds open on a rolling window, often up to six months ahead, while some open a set block of dates on one release day. Each campground’s official page lists its window. Our release-day guide explains the common patterns.
Can Nabbi reserve the site for me?
No. We never book or hold sites, because that would take them away from other campers. You book in your own name on the official site. If you’d like a person to help, try Concierge.
What about first-come, first-served campgrounds?
If a campground doesn’t take reservations, there’s no calendar to watch, so it won’t appear on Nabbi. The park’s website usually posts when its walk-up sites tend to fill.
Do you watch group sites and RV sites?
We watch the sites the official system lists for the campground. Set your group size and the number of nights, and check the site type in the booking page before you pay.
My campground isn’t listed.
Search for its name or paste its recreation.gov link on the browse page. If it’s on another booking system, let us know.
