search_permitsread-onlyFind US backcountry and wilderness permits by name, park, trail or area, for hikes, climbs, river trips and overnight trips in national parks, national forests and state parks. Use this when someone asks how to get a permit or which permit a trip needs. Returns up to 10 permits with their PermitSnag page and whether PermitSnag scans them for cancellation openings.

get_permit_detailsread-onlyGet the rules for one US backcountry or wilderness permit: how it is issued (reservation, lottery or in person), its season, lottery and release dates, closures, group size limit, and the official agency page.

search_campgroundsread-onlyFind campgrounds in the US by name, area or state, across Recreation.gov and state park booking systems. Use this when someone wants a place to camp or asks about a specific campground. Returns up to 10 campgrounds with their PermitSnag page, their booking system, and whether PermitSnag can send an alert when a site opens. It does not check dates; use check_availability for that.

Says whether PermitSnag can send an alert when a site opens, and whether our checks count individual sites or only the campground as a whole.
