Ranger is an outdoor trip-planning service that helps campers find reservable campsites and build trips around them. Search by park or area and travel dates to check live availability across more than 40,000 campgrounds in all 50 states and Washington, DC. Ranger searches Recreation.gov and state park listings, ranks campsites that can actually be booked, and suggests nearby alternatives when a first choice is full. Planning is free, and no account is needed.

Beyond campsite search, Ranger offers curated trip plans for destinations such as Yosemite, Zion, Acadia, and Olympic National Park. Plans bring together campground options, trails, and ideas for local activities, with rainy-day suggestions when the forecast changes. Live weather, wildfire, river, air-quality, and park alerts inform trip safety scores and planning. Campers can also request free cancellation texts: Ranger checks booked campgrounds regularly and sends an alert with a booking link if a site opens for their dates. Ranger Pro adds daily monitoring of saved trips for changes such as hazards, weather, water conditions, or closures.
