How our campground availability alerts work

We do the watching. You do the booking. Here's how our free campground availability and campsite cancellation alerts help you land sold-out campgrounds on Recreation.gov and state park systems.

1. Choose a Campground

Select the campground you want to visit. We support Recreation.gov and many state park systems.

2. Set Your Dates

Tell us when you want to camp. We'll start monitoring availability for those specific dates.

3. Get Notified Instantly

When a site opens up, we'll alert you via email, SMS, or push notification within seconds.

4. Book It Yourself

Click the link in your alert to go directly to the booking page. You complete the reservation on the official site.

Remember: We notify you of availability, but you book directly through the official reservation system. No middleman, no extra fees.

Frequently asked questions

Our system automatically checks campground availability every 2 minutes across 150,000+ campsites. When a reservation is cancelled and a site becomes available that matches your alert criteria (dates, campground, etc.), we instantly notify you via email, SMS, or push notification so you can book it before anyone else.

Yes! Free accounts get 1 active campground alert with 5-minute scans and full SMS/email/push notifications. Premium Members ($60/year) get 5 alerts with faster 2-minute scans. Need even more? Purchase additional alert packs anytime. Unlike competitors who charge $10-50/month, everyone gets access to our powerful alert system.

We monitor all campgrounds on Recreation.gov (national parks, national forests, BLM lands, Army Corps of Engineers) plus state park systems including ReserveCalifornia, ReserveAmerica, and many others. This includes popular destinations like Yosemite, Joshua Tree, Big Sur, Yellowstone, Zion, Grand Canyon, and thousands more.

Our system scans for availability every 2 minutes and sends notifications within 30 seconds of detecting an opening. This speed is critical because popular campsites at places like Yosemite or Big Sur often get rebooked within minutes of a cancellation.

No, we don't book campsites for you. When we detect availability, we send you an alert with a direct link to the official reservation site (Recreation.gov or the park's booking system). You complete the booking yourself - no middleman, no extra fees, no markup.

Outdoorithm includes alerts free with every account. Campnab charges $10-20/month, The Dyrt charges $9-24 per scan. We monitor 150,000+ campsites and offer email, SMS, and push notifications. Premium members get higher limits and faster scans.

Set up alerts early and be flexible with your dates (weekdays have more cancellations). Be ready to book immediately when you receive a notification - have your Recreation.gov account logged in and payment info saved. Most cancellations happen 1-2 weeks before the reservation date. Setting alerts for multiple campgrounds increases your chances.

You can set alerts for entire campgrounds or filter by specific criteria like site type (tent, RV, cabin), amenities, or loop. This lets you target exactly the kind of campsite you're looking for rather than getting notifications for sites that don't meet your needs.

Recreation.gov reservations typically open at 7:00 AM Pacific Time (10:00 AM Eastern), 6 months in advance on a rolling basis. ReserveCalifornia reservations open at 8:00 AM Pacific Time, also 6 months in advance. Use our free booking window calculator to find the exact release date for your target campground and set alerts for both new releases and cancellations.

Yes, using campsite availability alerts is completely legal. We simply monitor publicly available information on Recreation.gov and state park booking systems, then notify you when availability changes. You still book directly through the official reservation sites using your own account. We don't bypass any systems or make bookings on your behalf.
