CampFinderFree Campnab alternative (2026): what you give up and what you don't
Campnab is the tool most people hear about first when they go looking for a way to grab a cancelled campsite. It has been around the longest, it covers the most reservation systems, and it works. It also starts at $10 a month with no free tier, and the fastest scans cost $30 a month. If you camp three weekends a summer, that's a lot of money for a service you use for a few weeks.
This post is an honest comparison. I built CampFinder, so I have a stake in it, but I'd rather you pick the right tool than pick mine and be disappointed. Where Campnab is better, I say so.
What Campnab charges in 2026
From campnab.com/pricing as of September 2026:
- Good: $10/month or $90/year, 3 active scans, "standard scanning"
- Better: $20/month or $180/year, 5 scans, "checks more often"
- Awesome: $30/month or $270/year, 7 scans, "checks most often"
- Pay-per-use: $10, $15 or $20 for a single park and date range
Campnab no longer publishes numeric scan intervals; the tiers are described only as standard, boosted and priority. Older reviews put the range at roughly every 10–15 minutes on the cheapest tier down to every few minutes on the most expensive.
What the free options actually are
There are three worth knowing about, and they overlap less than you'd expect.
Recreation.gov's own Availability Alerts. Free, built into the site, and the first thing you should set up if your campground is on Recreation.gov. The limits: you can have only 3 active alerts at a time, alerts are set at the campground level (with filters like site type) rather than for a specific site, and every person with an alert on the same dates gets the same email at the same moment. Recreation.gov says so itself: the alert "will be sent to everyone who has alerts set for the same date." For a popular campground that can be several hundred people. Read more about the 3-alert limit and how to work around it.
Campflare. Free, donation-funded, US only, and fast. It covers nearly every campground reservable on Recreation.gov plus most US state systems, and sends email and text alerts. If you camp only in the United States and speed is what matters, Campflare is a very good choice and I'd tell you that even if I hadn't built anything.
CampFinder (this site). Free, no ads, up to 100 watches per account, email alerts. Covers Recreation.gov, a dozen US state and county systems that run on the UseDirect platform (California, Washington, Arizona, Michigan, Minnesota, Missouri, Ohio, Virginia, Wisconsin and others), and the GoingToCamp systems used by Washington State Parks and most of Canada: Parks Canada, BC Parks, Ontario Parks, Manitoba, New Brunswick, Nova Scotia, Newfoundland and Labrador, Yukon, Northwest Territories, and several regional park authorities. Full list with live examples on the Coverage page.
What you give up going free
Be clear-eyed about this.
Speed. Campnab's paid tiers and Campflare check far more often than CampFinder does. CampFinder checks every 30 minutes. For the ten hottest campgrounds in North America in July, Upper Pines, Kalaloch, Many Glacier, Slough Creek and their peers, a cancellation is gone within a minute or two, sometimes within seconds. A 30-minute check will miss most of those. If you are hunting one specific weekend at one of those campgrounds, pay for a fast scanner and don't feel bad about it.
Text messages. CampFinder is email only. Campnab and Campflare both text you. If you don't have email notifications turned on for your phone, a text is faster to notice.
Some systems. Campnab covers ReserveAmerica states (Texas, New York, Colorado and about forty others) and some county and utility systems that CampFinder does not yet. Nobody free covers Alberta Parks, Saskatchewan or Quebec's Sépaq well. Yellowstone's Xanterra-run campgrounds are hard for everyone.
Auto-booking. None of these tools book for you, and you should be suspicious of any that claim to. Recreation.gov's terms and the federal BOTS Act both matter here, and a bot that books faster than humans doesn't fix the problem, it just moves it to whoever pays for the bot.
What you don't give up
Most campgrounds, most of the time. The famous campgrounds are the exception, not the rule. Somebody in r/camping recently logged two weeks of Recreation.gov cancellations and found the Yosemite Valley campgrounds reopened about 0.3% of booked nights, while ordinary Forest Service and state park campgrounds turned over 7–14%. At the ordinary places, a cancellation sits for hours, not seconds, and a 30-minute check catches it. That's the vast majority of trips.
Canada. This is the biggest practical difference. Campflare doesn't cover Canada at all. Campnab does, at $10+/month. CampFinder covers Parks Canada, BC, Ontario and most other provinces for free. If you're trying to get into Algonquin, Killarney, Alice Lake or Lake Louise, this is your free option.
Watching a lot of places at once. Recreation.gov caps you at 3 alerts and Campnab's $10 tier at 3 scans. If you'd rather cast a wide net (any campground within 50 miles of Mount Rainier for any two nights in August, say), CampFinder's radius search and 100-watch allowance are built for exactly that, and that's usually the fastest way to actually end up camping.
Money. A summer of Campnab's middle tier is about $80. That's a tent-site night in most national parks.
How to decide in one minute
- Hunting one specific weekend at a top-ten famous campground, US only: Campflare, or pay for Campnab's top tier if you want SMS and the widest coverage.
- Anything in Canada, or a mix of US and Canada: CampFinder, or Campnab if you need texts and ReserveAmerica states.
- Flexible dates or flexible campgrounds anywhere CampFinder covers: CampFinder, and set a wide radius.
- Only care about one Recreation.gov campground and want zero setup: Recreation.gov's own alerts, and add a CampFinder watch as a backup because the Rec.gov email goes to everyone at once.
Whichever you use, do the one thing that matters more than the tool: stay logged in to the reservation site on your phone with a payment method saved, so booking is two taps and not a login screen. Most people who lose a cancellation lose it there.
