In-Depth Comparison
Both tools alert you when campsites open up. But the details matter — scan frequency, site coverage, pricing, and alert channels can mean the difference between booking that site and missing it.
Try Camping Alert FreeCampnab was the first campsite monitoring tool and built the category. Camping Alert is built for campers who want faster scans, smarter search, and granular date matching — at a lower price.

Both Camping Alert and Campnab scan every 5 minutes on paid plans. The key difference: Camping Alert includes a free tier with 30-minute scans — so you can try the service before paying. Campnab requires payment before you receive a single alert.
On Campnab's entry plan, scans happen every 15 minutes. You need their premium tier to reach 5-minute scans, which costs more per alert than Camping Alert's monthly subscription covering unlimited searches.
Campnab requires you to specify exact check-in and check-out dates. If you're flexible — "I'll take any Friday–Sunday in July" — you'd need to create a separate alert for each weekend, paying per alert.
Camping Alert's natural-language date input lets you set a single alert for "any weekend in July" or "3-day weekends in August." One alert covers all matching date combinations, saving both setup time and money.
Campnab monitors one campground per alert. Camping Alert's Explorer and Backcountry plans let you monitor multiple campgrounds, an entire park, or any campground within a geographic radius — all under a single alert.
If your priority is Yosemite Valley specifically, both tools cover it. But if you're open to any site within 50 miles of a location, only Camping Alert can handle that efficiently.
Campnab notifies you when a site opens. It doesn't help you figure out which dates are most likely to have cancellations, or when to check most actively.
Camping Alert adds a cancellation probability score based on historical drop rates, current booking percentage, lead time, and holiday patterns. You can see at a glance which upcoming dates are high-probability vs. low-probability — before you even set an alert.
On comparable paid tiers, scan speeds are similar — both reach 5-minute intervals. The bigger speed advantage is in notification delivery: Camping Alert sends SMS alerts (Explorer+) which reach you faster than email, and direct booking links in the message mean you can act in under 30 seconds.
Yes. Create a free account on Camping Alert, search for your campground, and set up an alert in about 2 minutes. You can run both services simultaneously while evaluating, then cancel whichever you prefer.
Both services pull from Recreation.gov, which covers over 4,600 campgrounds on federal land — national parks, national forests, BLM land, and Army Corps of Engineers sites. If the campground is bookable on Recreation.gov, Camping Alert monitors it.
Camping Alert's free tier gives you one active alert with email notifications — no credit card required. Campnab's entry tier charges per alert. For a single use case, Camping Alert's free plan is the better starting point.
Campnab charges per alert — a busy summer with multiple campground searches can add up quickly. Camping Alert's Explorer plan at $7.99/month gives you 10 simultaneous alerts with flexible dates and SMS. The Backcountry plan at $100/year is unlimited. If you camp more than a few times per year, the subscription model saves money.
Set up your first alert in 2 minutes. No credit card required.
