You are able to search by coordinates using the web platform at AllTrails.com. However, when you use the Explore search bar to search, the results will not direct you to the exact location of your coordinates, but to the nearest trail or town to that location.
If you'd like to find the exact position of that coordinate, you'll need to add those coordinates to a waypoint on a map, which can be done on our web platform. The steps can be found in this link: Adding a Waypoint to add a new waypoint to the map.
When searching with coordinates, the format needs to be in decimal degrees. Below are examples of the correct format as well as the incorrect formats.
37.773972. N, -122.431297. W
