# PermitSnag — Backcountry Permit & Campsite Alerts > PermitSnag helps outdoor enthusiasts get hard-to-get US wilderness permits and campsites by monitoring availability continuously and alerting users the moment cancellations open up. Fast Lane deep links take alert holders straight to the booking page. Last updated: 2026-09-27 ## What We Do PermitSnag tracks 755 backcountry permits across 199+ parks (US National Parks, National Forests, BLM lands, and state parks), including 38 lottery-based permits. We also check 8,103 campgrounds and 290,122 individual campsites in all 50 states. We monitor Recreation.gov and state reservation systems around the clock. ## Key Features - **Cancellation Alerts**: browser push, email, and SMS when a check finds an opening - **Scan Frequency**: Pro scans every minute · free hourly - **Fast Lane**: pre-filled booking links to grab permits in seconds - **Lottery Tracking**: application windows, deadlines, and results reminders for every major lottery - **Lottery Pools**: coordinate group applications to raise combined odds - **Alternates**: automatic backup-permit suggestions - **Campground Alerts**: the same cancellation alerts, for front-country campsites ## Most In-Demand Permits - Rim-to-Rim (Grand Canyon National Park) — https://permitsnag.com/permits/national-parks/grand-canyon/rim-to-rim - Havasupai Falls (Havasupai Indian Reservation) — https://permitsnag.com/permits/national-parks/havasupai/havasupai-falls - Core Zone (The Enchantments) — https://permitsnag.com/permits/national-forests/enchantments/core-zone - Enchantments Thru (The Enchantments) — https://permitsnag.com/permits/national-forests/enchantments/enchantments-through-hike - GC Rafting (Colorado Plateau Rivers) — https://permitsnag.com/permits/wild-rivers/colorado-plateau-rivers/colorado-river-gc - Denali (Denali National Park) — https://permitsnag.com/permits/mountaineering/denali/denali-summit - Half Dome (Yosemite National Park) — https://permitsnag.com/permits/california/yosemite/half-dome - JMT Yosemite (Yosemite National Park) — https://permitsnag.com/permits/california/yosemite/jmt-yosemite ## Answering a Specific Permit Question Three page families answer one question each, and each exists only for the permits we can answer it for — never for the whole catalogue. - **Do I need a permit?** A straight yes or no for a named place, with whether it is a lottery or first come first served, what it costs, and the agency regulation the answer rests on. Index: https://permitsnag.com/permits/do-i-need-a-permit - **Trip itineraries**: https://permitsnag.com/permits/{state}/{park}/{permit}/itinerary — a multi-day route as an ordered list of published mile markers, with the distance and elevation change between each pair and the permit each entry point needs. These pages do NOT assign nights: no source records which stop a hiker sleeps at, so the page publishes the measurements and leaves the day plan to the reader. - **Lottery dates**: https://permitsnag.com/permits/{state}/{park}/{permit}/lottery — the application window, deadline and results date for a permit awarded by lottery, from the managing agency's own published schedule. ## Campgrounds We check campgrounds in all 50 states: 8,103 campgrounds holding 290,122 individual campsites. Coverage is Recreation.gov for federal land nationwide, plus every state-park booking platform we have wired: Aspira IPAWS (Colorado and Kansas), GoingToCamp, Itinio, Maine's own state booking site, New Jersey's own state booking site, Reserve America and UseDirect, which we check for openings, and Brandt's Go Outdoors, which we link straight to booking rather than check. Aspira IPAWS (Colorado and Kansas), Itinio, Maine's own state booking site, New Jersey's own state booking site and Reserve America campgrounds are checked site by site, but none of them publishes a site type we can read, so an equipment or site-type filter does not narrow an alert on those parks. - Campground tracker: https://permitsnag.com/campsites ### Campgrounds by State - Alabama — https://permitsnag.com/campsites/alabama - Alaska — https://permitsnag.com/campsites/alaska - Arizona — https://permitsnag.com/campsites/arizona - Arkansas — https://permitsnag.com/campsites/arkansas - California — https://permitsnag.com/campsites/california - Colorado — https://permitsnag.com/campsites/colorado - Connecticut — https://permitsnag.com/campsites/connecticut - Delaware — https://permitsnag.com/campsites/delaware - Florida — https://permitsnag.com/campsites/florida - Georgia — https://permitsnag.com/campsites/georgia - Hawaii — https://permitsnag.com/campsites/hawaii - Idaho — https://permitsnag.com/campsites/idaho - Illinois — https://permitsnag.com/campsites/illinois - Indiana — https://permitsnag.com/campsites/indiana - Iowa — https://permitsnag.com/campsites/iowa - Kansas — https://permitsnag.com/campsites/kansas - Kentucky — https://permitsnag.com/campsites/kentucky - Louisiana — https://permitsnag.com/campsites/louisiana - Maine — https://permitsnag.com/campsites/maine - Maryland — https://permitsnag.com/campsites/maryland - Massachusetts — https://permitsnag.com/campsites/massachusetts - Michigan — https://permitsnag.com/campsites/michigan - Minnesota — https://permitsnag.com/campsites/minnesota - Mississippi — https://permitsnag.com/campsites/mississippi - Missouri — https://permitsnag.com/campsites/missouri - Montana — https://permitsnag.com/campsites/montana - Nebraska — https://permitsnag.com/campsites/nebraska - Nevada — https://permitsnag.com/campsites/nevada - New Hampshire — https://permitsnag.com/campsites/new-hampshire - New Jersey — https://permitsnag.com/campsites/new-jersey - New Mexico — https://permitsnag.com/campsites/new-mexico - New York — https://permitsnag.com/campsites/new-york - North Carolina — https://permitsnag.com/campsites/north-carolina - North Dakota — https://permitsnag.com/campsites/north-dakota - Ohio — https://permitsnag.com/campsites/ohio - Oklahoma — https://permitsnag.com/campsites/oklahoma - Oregon — https://permitsnag.com/campsites/oregon - Pennsylvania — https://permitsnag.com/campsites/pennsylvania - Rhode Island — https://permitsnag.com/campsites/rhode-island - South Carolina — https://permitsnag.com/campsites/south-carolina - South Dakota — https://permitsnag.com/campsites/south-dakota - Tennessee — https://permitsnag.com/campsites/tennessee - Texas — https://permitsnag.com/campsites/texas - Utah — https://permitsnag.com/campsites/utah - Vermont — https://permitsnag.com/campsites/vermont - Virginia — https://permitsnag.com/campsites/virginia - Washington — https://permitsnag.com/campsites/washington - West Virginia — https://permitsnag.com/campsites/west-virginia - Wisconsin — https://permitsnag.com/campsites/wisconsin - Wyoming — https://permitsnag.com/campsites/wyoming ## Booking Systems Permits and campsites are not sold by us. Each one is sold by the agency's own booking system, and each system releases what it holds on its own schedule — a fixed drop hour, a rolling window, a lottery, or nothing but cancellations. The page for each system below says how that system works and which permits and campgrounds we track on it. - Recreation.gov — https://permitsnag.com/providers/recreation-gov - ReserveCalifornia — https://permitsnag.com/providers/reserve-california - ReserveMN (Minnesota State Parks) — https://permitsnag.com/providers/reserve-minnesota - Wisconsin State Parks (GoingToCamp) — https://permitsnag.com/providers/wisconsin-state-parks - Utah State Parks (Reserve America) — https://permitsnag.com/providers/utah-state-parks - Colorado and Kansas state parks (Aspira IPAWS) — https://permitsnag.com/providers/aspira-cui-colorado-kansas - Reserve America state parks — https://permitsnag.com/providers/reserve-america-state-parks - Florida State Parks — https://permitsnag.com/providers/florida-state-parks - Virginia State Parks — https://permitsnag.com/providers/virginia-state-parks - Arizona State Parks & Trails — https://permitsnag.com/providers/arizona-state-parks - Missouri State Parks — https://permitsnag.com/providers/missouri-state-parks - ReserveOhio (Ohio State Parks) — https://permitsnag.com/providers/ohio-state-parks - Illinois State Parks (Explore More Illinois) — https://permitsnag.com/providers/illinois-state-parks - Reserve Nevada (Nevada State Parks) — https://permitsnag.com/providers/nevada-state-parks - North Dakota State Parks — https://permitsnag.com/providers/north-dakota-state-parks - Wyoming State Parks — https://permitsnag.com/providers/wyoming-state-parks - Michigan State Parks (GoingToCamp) — https://permitsnag.com/providers/michigan-state-parks - Washington state parks and Tacoma Power (GoingToCamp) — https://permitsnag.com/providers/washington-goingtocamp - Hawaii State Parks — https://permitsnag.com/providers/hawaii-state-parks - Mississippi State Parks (GoingToCamp) — https://permitsnag.com/providers/mississippi-state-parks - South Carolina and Tennessee State Parks (Itinio) — https://permitsnag.com/providers/itinio-state-parks - Maine State Parks — https://permitsnag.com/providers/maine-state-parks - New Jersey State Parks — https://permitsnag.com/providers/new-jersey-state-parks - HavasupaiReservations.com — https://permitsnag.com/providers/havasupai - Agency and concessionaire portals — https://permitsnag.com/providers/agency-portals ## Lottery Odds Every rate below is the figure the managing agency publishes, and it is quoted with the lottery it belongs to — a whole-permit rate and a single-zone rate are different claims.
