Plan the camping trip. We’ll help you land the site.
Where to go, what to pack, and a watch across the major reservation systems, so the moment a sold-out site opens, you’re the first to know.
How It Works
From discovery to adventure in three simple steps
Search
Search 10,600+ public campgrounds by location, activity, or what matters to your family.
Compare
Compare campgrounds with AI-analyzed reviews, 5-year weather history, and community safety scores.
Go
Set a free alert, pack your list, and go. We monitor availability continuously — faster during peak cancellation windows — and notify you when spots open.
Plan the whole trip in one place
Everyone else helps you look. Tell Outdoorithm the trip you want and we match the campground to your family, build the packing list from your gear, and keep watch until a site opens.
Describe the trip you want
Where you're leaving from, who's coming, and when. No filters to wrestle — just tell us in a sentence.
Get picks matched to your family
Campgrounds ranked for your crew and your camping taste, with AI-analyzed reviews, weather, and safety already checked.
Pack with a list built for it
A packing list drawn from the campground and your trip, sourced from our gear catalog — core gear first, extras clearly optional.
We watch until a site opens
We keep watch across the major reservation systems and tell you the moment a site opens — then hand you a one-tap booking link.

What makes us different
We combine AI-analyzed reviews, 5-year weather history, and community safety scores with a public-lands-only focus and a mission that gives back.
Community safety scores.
Our Green Book classifies 1.2M+ reviews for discrimination reports, community tone, and safety — so every family can camp with confidence.
AI-analyzed reviews.
We've analyzed 1.9M+ real reviews across 10,600+ campgrounds with AI, distilling what campers actually say into clear, actionable insights.
Public lands only.
We list front-country, drive-to campgrounds with facilities. No dispersed or secret spots — responsible, beginner-friendly, and protective of fragile places.
Free availability alerts.
Popular sites book fast. Start free with smart scans (every 5–15 min), then upgrade to a paid plan for priority scans (every 1–2 min) during peak cancellation windows.
