Scan Speed

Camping Alert scans every 5 minutes on paid plans, and every 60 minutes on the free tier — no credit card required. Campnab's speed depends on which tier you pay for: their entry plan scans every 10–15 minutes, and only their top $30/mo plan reaches 1–4 minutes, faster than our flat rate.

Matching Campnab's fastest tier costs roughly 4× what Explorer costs for scan speed alone — and still doesn't include natural-language dates, area search, cancellation probability scores, or a free tier. Raw scan speed isn't the whole picture: SMS delivery, direct booking links, and knowing when to check (probability scoring) often matter more than shaving a few minutes off the interval.

Date Flexibility

Campnab supports a "Flexible Dates" option covering up to a 7-day arrival window per scan. If you're open to a broader range — "any weekend this summer" — you'd need multiple scans to cover it.

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 across a much wider window, with no extra setup.

Search Coverage

Campnab lets you select up to 6 campgrounds per scan. Camping Alert's Explorer plan covers up to 5, and Backcountry covers up to 20 — plus whole-park mode (every loop in a park, uncapped) and area search (any campground within a radius), neither of which Campnab offers at any price.

If your priority is a handful of specific campgrounds, both tools can cover it. But if you're open to any site within 50 miles of a location, only Camping Alert can handle that in one alert.

Cancellation Intelligence

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.

Common Questions

Is Camping Alert actually faster than Campnab?

Honestly — Campnab's top $30/mo tier scans faster than our flat 5-minute paid rate (down to 1–4 minutes). Matching that speed costs about 4× what Explorer costs, though, and still skips natural-language dates, area search, and probability scoring. Camping Alert's SMS alerts (Explorer+) and direct booking links mean you can act in under 30 seconds once notified — speed of delivery, not just speed of scanning, is what usually decides whether you get the site.

Can I switch from Campnab to Camping Alert easily?

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.

Does Camping Alert cover the same campgrounds as Campnab?

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.

What if I only need one alert?

Camping Alert's free tier gives you 2 active alerts 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.

How does Camping Alert's pricing compare long-term?

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.
