NorCamp is a comprehensive camping guide for Scandinavia (Denmark, Finland, Iceland, Norway and Sweden), covering both well known locations as well as smaller, hidden away sites. It's an one-man project and all data is collected and maintained in cooperation with campsite owners and NorCamp users.
You can search for or show all campsites near your location on a map (Google Maps, OpenStreetMap or offline map) and get detailed information about them such as address, email, website, phone number, photos, reviews, price range and number of cabins and rooms. You can also submit reviews for a campsite, rate it, or upload photos. The project lives from the support of its users.
