Why this exists
Rail-trail information is scattered across paywalled apps, county PDFs and out-of-date guidebooks. BikeTheRail collects it into one open dataset, keeps it current automatically, and publishes it under the same license as OpenStreetMap so anyone can build on it.
Help make it better
Every trail page has a report button. If you know a trail that's missing, the fastest fix is to map it in OpenStreetMap; it will appear here the next night. How it works.
