The collaborative guidebook for climbers


Move around the map or search by name to find your favorite route or next project. Plan your trip with gigapixel-scale topos and descriptions by local experts.

Then bring all of Boltline to the crag with our iOS app.


Much like Wikipedia, Boltline's content is managed by members of the community. If you have first-hand knowledge of a climb or area, please consider:

  • Fixing any errors
  • Adding missing climbs/areas/topos
  • Improving descriptions or adding context
