It monitors sold-out campgrounds continuously and, on supported reservation systems, loads the freed-up site into your cart and pushes you a notification. It also searches availability across major reservation systems in one place. You always complete the booking yourself — the app removes the refreshing and the race to click, not your control of checkout. ### Key capabilities - **Automatic add-to-cart**: When a cancellation is detected at a campground you're watching, the app adds the open site to your cart before other users can claim it and notifies you. Covered systems: Recreation.gov, five US state park systems (Florida, Michigan, Mississippi, Washington, Wisconsin), and Canada (British Columbia, Manitoba, Newfoundland, Nova Scotia, and Parks Canada). - **Cancellation alerts**: Beyond auto add-to-cart, Campsite Tonight sends alerts for additional state and county systems, including California (ReserveCalifornia) and county parks. - **24/7 monitoring**: Real-time availability checks — as fast as about every 20 seconds for popular campgrounds. - **Search everything at once**: Browse availability across Recreation.gov, state parks, and county parks in a single search. - **Free to try, subscription for automation**: Searching and browsing is free. Cancellation alerts and automatic add-to-cart are on the paid plan. ### FAQ - **How does automatic add-to-cart work?** Campsite Tonight monitors sold-out campgrounds continuously. When a cancellation opens a matching site, the app adds it to your cart on supported systems and notifies you, so you're one tap from checkout. - **Does it book the campsite for me?** No — it adds the site to your cart and alerts you; you review and complete checkout and payment yourself. - **What's covered by automatic add-to-cart?** Recreation.gov, five US state park systems (FL, MI, MS, WA, WI), and Canada (BC, MB, NL, NS, Parks Canada).

Automatic add-to-cart is live on Recreation.gov (US national parks and forests), Florida, Michigan, Mississippi, Washington and Wisconsin state parks, and in Canada: British Columbia, Manitoba, Newfoundland, Nova Scotia, and Parks Canada. How it works: pick a campground and dates and turn on auto add-to-cart; the app scans the reservation system around the clock; the instant a matching cancellation appears it adds the site to your cart and notifies you; you complete checkout. Distinct from alert-only tools, which notify you and leave you to race to book. --- ## How to Book a Sold-Out National Park Campsite URL: https://campsitetonight.app/book-sold-out-campsites A "sold-out" campground almost always frees up sites as campers cancel — cancellations happen constantly, often within days of the stay, and on Recreation.gov a cancelled site returns to inventory immediately. At popular parks a freed-up site can be re-taken within minutes, so refreshing the page yourself rarely works. Campsite Tonight monitors sold-out campgrounds 24/7 and, on Recreation.gov and other supported systems, automatically adds a freed-up site to your cart the instant it appears, so you just check out. It does not book for you; you complete checkout. --- ## How to Book California Campgrounds URL: https://campsitetonight.app/book-california-campgrounds California camping spans three reservation systems — ReserveCalifornia (state parks; six-month rolling window, releases 8:00 AM Pacific), Recreation.gov (national parks and forests), and county park systems. Campsite Tonight searches all of them in one place, tracks cancellations, and shows which California state-park sites are releasing each day. Automatic add-to-cart applies to California's federal (Recreation.gov) campgrounds; California state parks (ReserveCalifornia) and county parks get cancellation alerts. --- ## Compare: Campsite Tonight vs Campnab and Campflare URLs: https://campsitetonight.app/compare/campnab and https://campsitetonight.app/compare/campflare Campnab and Campflare are both alert-only: they notify you when a cancellation appears and you book manually. Campsite Tonight goes further and automatically adds the open site to your cart on supported systems. Campnab covers the US and Canada with cancellation alerts (roughly 1–15 minute scanning depending on plan; web-based). Campflare is a free, US-only alert service (Recreation.gov plus state parks it says span all 50 states). Campsite Tonight covers the US and Canada, scans as fast as ~20 seconds, and is the one that adds the site to your cart rather than only alerting you. --- ## Browse Parks & Campgrounds URL: https://campsitetonight.app/parks Directory of every park Campsite Tonight tracks, grouped by state and sorted by campground count. Covers thousands of parks — every US national park, national forests (Shasta-Trinity, Eldorado, Tahoe, Sequoia, Stanislaus, and more), Bureau of Land Management sites, state parks, and Army Corps of Engineers campgrounds. Each park links to a park-level detail page with the campground list, weekend availability, primary photo, and per-campground booking analytics. --- ## Campgrounds Near Me URL: https://campsitetonight.app/campgrounds-near-me Geolocated finder. Uses the visitor's IP location (via Vercel edge headers) to surface nearby campgrounds with weekend availability plus a curated list of nearby parks. Coverage spans all 50 states with real-time availability data for the coming weekend. Falls back to a generic browse experience when geolocation isn't available. --- ## California State Parks Releasing Sites Today URL: https://campsitetonight.app/california-releasing-sites Daily-refreshed list of California State Park campgrounds that are releasing new reservations today via ReserveCalifornia. California State Parks release reservations on a rolling 6-month window at 8:00 AM Pacific Time. This page shows which campgrounds are opening new dates today, grouped by park, with the specific camping dates each release covers. Especially useful for planning bookings at competitive California parks like Big Sur (Julia Pfeiffer Burns, Andrew Molera, Pfeiffer Big Sur), Mendocino, Half Moon Bay, Doheny, Refugio, and Emerald Bay. --- ## Recreation.gov Cancellation Alerts + Auto Add-to-Cart URL: https://campsitetonight.app/recreation-gov-cancellation-alerts How Campsite Tonight handles Recreation.gov cancellations, and when those cancellations actually appear. ### The core problem Popular Recreation.gov campgrounds like Yosemite's Upper Pines are booked out months in advance. Cancellations happen constantly but disappear in seconds — by the time a human sees an alert, opens the site, logs in, and adds it to cart, someone else has claimed it. Alert-only services notify you and leave you to race. ### How Campsite Tonight is different Instead of only alerting you, Campsite Tonight adds the newly-available site to your cart on Recreation.gov, then notifies you. You open the notification and check out — no race. You always complete checkout and payment yourself; the app does not auto-purchase. ### Coverage Automatic add-to-cart runs on Recreation.gov (national parks and forests), five US state park systems (Florida, Michigan, Mississippi, Washington, Wisconsin), and Canada (British Columbia, Manitoba, Newfoundland, Nova Scotia, Parks Canada). Additional state and county systems get cancellation alerts. For head-to-head comparisons with other tools, see https://campsitetonight.app/compare/campnab and https://campsitetonight.app/compare/campflare. ### Timing patterns (Upper Pines example) - Openings happen throughout the day, not concentrated at midnight. Roughly 60–70% happen during waking hours (8 AM–8 PM PT). - Lead time before check-in is heavily last-minute: most openings appear in the 0–3 day window before the stay date. ### FAQ - **How is this different from an alert service?** Alert services notify you and you race to book. Campsite Tonight adds the site to your cart, so there's no race. - **Does it book the site for me?** No — Recreation.gov does not allow third parties to complete a purchase for you. Campsite Tonight adds the site to your cart and you complete checkout. - **When do reservations open?** Recreation.gov usually releases campsites six months in advance at 10 a.m. Eastern; California state parks (ReserveCalifornia) release at 8 a.m. Pacific. --- ## Research: When Do Campsite Cancellations Actually Appear? URL: https://campsitetonight.app/research/when-do-campsite-cancellations-appear Published 2026-07-01. Original data from the 10 most-requested campgrounds on Campsite Tonight — the ones users create the most alerts for — looking at every detected opening in June 2026. Each campsite is counted at most once per hour per date, so repeated detections aren't double-counted. ### Method - 90-day alert-volume ranking picks the top 10 tracked campgrounds. - All discovered openings for those campgrounds during June 2026 are deduped by (campgroundId, siteId, date-in-PT, hour-in-PT). - Analyses cover: hour-of-day distribution, day-of-week distribution, and lead-time distribution before check-in. ### Findings - Cancellations are not evenly distributed but they are not concentrated at midnight either. There is a slight morning peak; the majority of openings happen throughout waking hours. - Most openings appear less than a week before the check-in date. Very few are more than two weeks out. - Weekday distribution is roughly uniform — Fridays and Saturdays show a small bump. ### The campgrounds analysed Upper Pines, Lower Pines, and North Pines (all Yosemite), Watchman (Zion), Mather (Grand Canyon), plus five other campgrounds that rotate into the top 10 based on real-time alert volume. --- ## FAQ URL: https://campsitetonight.app/faq The full FAQ page is hosted on Webflow at the URL above.
