2026 Comparison
Texas campgrounds sell out months ahead, and cancellations vanish in minutes. Here’s an honest look at the tools that watch for those openings, whether you’re headed to a national park or a state park, and which one fits your trip.
See Camp.land pricing →Most campsite-alert tools you’ll find are built for Recreation.gov, the federal system that handles national parks and national forests. But Texas state parks don’t use Recreation.gov. They book through a separate system called ReserveAmerica (texasstateparks.reserveamerica.com).
That distinction matters when you pick a tool. Camp.land used to watch ReserveAmerica for Texas state parks. Today it tracks 49 national park campgrounds nationwide on Recreation.gov, including Big Bend and Guadalupe Mountains here in Texas. If you specifically need a Texas state park watched live, Campnab and Outdoorithm still support ReserveAmerica.
Each is the right answer for a different kind of trip.
Best for: National park campgrounds nationwide, on a budget
Best for: A free Texas alert (single park)
Best for: Multi-state campers & speed
Best for: People already using The Dyrt
Best for: National parks & federal land
If: You want a free single-park alert
→ Outdoorithm — genuinely free for one alert, with email + push.
If: You're headed to Big Bend, Guadalupe Mountains, or another of the 49 national park campgrounds Camp.land tracks
→ Camp.land — $10 once for one campground, or $5/month unlimited across all 49.
If: You camp across many states or want scans every 1–4 minutes and SMS
→ Campnab — the strongest general-purpose tool, covering Texas state parks and federal land alike.
If: You already plan every trip inside The Dyrt app
→ The Dyrt Alerts — just confirm it supports your specific park first.
If: You need alerts for a Texas state park specifically
→ Campnab or Outdoorithm — Camp.land no longer monitors ReserveAmerica live. We'll point you to cabins nearby instead.
Usually not. Most free alert tools (and many paid ones) are built for Recreation.gov, which handles national parks and federal land. Texas state parks book through a different system, ReserveAmerica (texasstateparks.reserveamerica.com), so a tool has to specifically support ReserveAmerica to watch a Texas state park. Campnab and Outdoorithm both do. Camp.land no longer does; it now tracks 49 national park campgrounds nationwide instead, including Big Bend and Guadalupe Mountains here in Texas.
Outdoorithm has a genuinely free tier (one active alert), so it is the cheapest way to watch a single Texas state park. Campnab is the other general-purpose option that covers Texas state parks, running $10-30/month. Camp.land does not offer Texas state park alerts anymore; it covers 49 national park campgrounds nationwide instead, including Big Bend and Guadalupe Mountains.
Fast, popular sites are often re-booked within minutes. A faster scan interval helps for the most contested sites, but at most parks a scan every 10 to 30 minutes still reliably catches cancellations, since released sites usually sit available longer than a few seconds. The bigger factor is acting quickly once you get the alert.
If you are watching Big Bend, Guadalupe Mountains, or any of the other 47 national park campgrounds Camp.land tracks, Camp.land is the cheaper option, $5/month unlimited or $10 once. If you need a Texas state park watched, or a national park outside our 49-campground list, Campnab is the stronger general-purpose pick since it covers both federal and ReserveAmerica parks nationwide.
$10 once for a single campground, or $5/month for unlimited alerts across all 49 we track. Cancel anytime.
