How to update or change information about a trail

Any suggested changes to a trail must first be evaluated by our moderators. This process may take some time depending on our backlog and our ability to verify the information. You can suggest changes to a trail by following these steps:

Via desktop or laptop:

1. Log into your account
2. Click on the trail card for the trail you want to update
3. Scroll down to the bottom of the trail page until you reach the review section. Under the 'Review Trail' button, click the link that says 'suggest edit'.
4. Make whatever edits you think are needed to improve the accuracy of the trail (trail name, trailhead location, length, difficulty level, whether dogs are permitted, etc.). You can also suggest a better-verified route and draw that route by clicking on 'Draw Route' under 'Step 1- Suggest a better route' in the top-left corner.
5. Click 'Save'

The trail segment data represented on the map types (the dashed lines that you see on the AllTrails, OSM, and OCM map type) is sourced from OpenStreetMap. OpenStreetMap is a collaborative, wiki-style project that aims to create the most detailed, up-to-date map of the globe. OpenStreetMap has a wide array of path classifications, some of which are not distinguished on AllTrails. Please note that in certain cases and for simplicity of reading our map types, many segments will be displayed and interpreted differently on our site than on OpenStreetMap's site.

If you see something in the dashed-line trail segments on our map types that's inaccurate or misleading, we recommend using OpenStreetMap's online platform to make the updates:

1. Visit https://www.openstreetmap.org/ 
2. Use the search bar to enter a nearby city or other geographical feature to narrow your view
3. Click on the arrow next to 'Edit' and select 'Edit with iD' from the dropdown
4. Zoom into the segment that needs to be edited, then click the segment to highlight it
5. In the left column, edit the segment's attributes — learn more about OSM's best practices for assigning attributes to a trail
6. When finished editing, click 'Save' at the upper right corner of the map

Note: When making edits on OSM, please do not delete the trail segments — doing this runs the risk of another OSM member adding back the segments with misleading attributes. Instead, please follow the above steps to adjust the segment's attributes. 

Edits made to OSM are not directly applied to the AllTrails map type. These edits are applied to the AllTrails map type periodically throughout the year.

For additional help in updating data on OpenStreetMap, we recommend visiting OSM's Report a problem / Fix the map page. Please note that after you make changes to OpenStreetMap, it may take 1-2 months for the updates to be reflected on AllTrails depending on when it falls in our data syncing cycle.
