# OpenCampsite > Campsite cancellation and availability alerts for sold-out campgrounds > across the US and Canada.

OpenCampsite is notification-only. It does not reserve, hold, or buy a campsite and cannot guarantee one will still be available. Campers book directly with the official reservation provider after an alert arrives. Supported reservation systems: Recreation.gov (campgrounds plus wilderness and day-use permits with lottery-window alerts — Half Dome, Mt. Whitney, The Wave, and 60+ more permit parks), ReserveCalifornia, Florida, Minnesota, Missouri, Ohio, Virginia & Arizona State Parks (UseDirect), ReserveAmerica (multi-state), Colorado Parks & Wildlife (cpwshop), Michigan DNR, Mississippi State Parks, Ontario Parks, BC Parks, Parks Canada, Washington State Parks, Wisconsin State Parks, Manitoba Parks, Nova Scotia Parks, Yukon Parks, Newfoundland & Labrador Parks, NWT Parks, a dozen municipal and conservation-authority systems on GoingToCamp (Tacoma Power, Muskegon County, Thunder Bay, and more), and Firefly Reservations.
