Some good directories for finding nearby camping sites in the United States and Canada are Go Camping America, USACAmpgrounds.info and Camping USA. For example, the resource USACAmpgrounds.info lists all 13,000 vehicle-accessible public campgrounds in the United States and Canada as of 2015. This directory has an interactive map tool and provides an accurate latitude and longitude for each site for GPS and mapping applications. The information for each campsite listing includes amenities, Web links and phone numbers.
The USACAmpgrounds.info directory includes all National Forest, National Park, State Park and Provincial campgrounds, as well as all Army engineers, military-only, TVA and BLM campgrounds. Many regional campgrounds are also on the list, including county-owned, city-owned and utility-owned campsites.
Another valuable resource is the KOA website, which features more than 485 privately owned campsite locations across North America and options for RV sites, tent sites and cabins.
Further suggestions for camping directories include Boondocking.org for no-facilities camping, the Ultimate US Public Campgrounds Project extensive directory and Visit USA.
Mobile applications, such as CampFone, All Stays Camp & RV and iOverlander, are also useful tools that feature directory listings and interactive maps. Camping directory applications are generally available for both iPhone and Android and are compatible with most smartphones, tablets and Web browsers.
