Snag sold-out campsites at Yosemite, Zion & Joshua Tree.

We currently monitor 11 major national parks including Joshua Tree, Yosemite, Zion, Grand Canyon, Glacier, Rocky Mountain, Acadia, and Great Smoky Mountains. We're expanding the list — more parks are coming soon.

You get an SMS with a direct deep-link to the campsite on recreation.gov. One tap opens the booking page. Log in and complete the reservation — the whole thing takes about 30 seconds.

On the Starter plan, you can have up to 3 active alerts at a time. Perfect if you're flexible on parks or dates. On the Unlimited plan, there's no cap — monitor as many parks and date ranges as you want.

Campflare is a solid free service with broad park coverage. The key difference is what happens when a site opens: CampSnag sends a direct deep link to the exact dates on recreation.gov so you can book in one tap — Campflare alerts you but you have to navigate there yourself. In peak season, those extra 30 seconds can cost you the site. We also focus specifically on the hardest-to-get parks and match your exact dates, so you only get texts that matter.

No — we alert you instantly so you can book it yourself. recreation.gov requires you to log in and complete the booking. We get you directly to the available dates; the final booking is yours.

When we detect an opening, we build a direct URL to that specific campsite on recreation.gov with your dates pre-selected. You tap the link in your SMS, log in to recreation.gov (you should stay logged in on your phone), and hit Reserve. The whole thing typically takes under 30 seconds — vs. 60–90 seconds navigating there yourself. In a competitive park, that difference matters.

No. We only alert you when a site matches your exact criteria — right park, right dates, right group size. If nothing opens, you hear nothing. We built smart deduplication so you won't get multiple texts for the same cancellation. One alert = one real, bookable opportunity.

Visit campsnag.com/manage, enter your email, and click "Manage Billing" to cancel anytime through the Stripe customer portal. You'll keep access until the end of your billing period. You can also cancel individual alerts from the same page without cancelling your whole subscription.

The moment you know you want to go. Cancellations happen year-round but spike on Sunday nights and 48–72 hours before a reservation date (when people's plans change). The earlier you set an alert, the more cancellation windows you catch. Most members snag a site within 2 weeks of setting their alert.
