At this time, we are not able to add trails in bulk to our database. However, AllTrails is in part a community-driven platform meaning our community can suggest the addition of new individual trails within a trail system. The way AllTrails is built is not to include every single segment within a trail system but rather trails (or combination of trails) that users would reasonably do and that start and end in the same place (unless they are point to point trails).
If you know of a trail that should be on AllTrails, please take a minute to add it. The AllTrails community will thank you! You can find information on adding a new trail to our system in the following link, How do I contribute a new trail to AllTrails?.
If you are connected to a park, tourism, or hiking organization, please refer to the following article for more information, I work for a park or trail system. How can I make edits to trails within our park/trail system?.
