A Point of Interest (POI) indicates a specific type of place. Some POIs (e.g. Trailheads and Campsites) will help with route logistics, others (Trail Obstacles and Water Sources) help with safely navigating the trail. Most of the remaining types will point out natural and historic attractions like Cabins, Lookouts, and Mountain Peaks.
On the map POIs will be shown using Pin Drop Icons. The image on the icon will vary depending on the POI type.
