Frequently asked
Questions about the map
Quick answers to what people ask before downloading the PDF or GPX.
Need help?
+34 644 199 430 1. Can I download the map for free?
Yes. We offer the map as a printable PDF (1 A4) and as GPX for GPS, both free with no sign-up. If you rent a bike with us, we also give you the printed map in the shop.
2. Is the GPX compatible with my GPS?
Yes. It’s a standard GPX file compatible with Garmin, Wahoo, Strava, Komoot, OsmAnd and any device or app that accepts tracks. It includes the 3 sections of the Y and all named waypoints.
3. Is there mobile signal along the whole trail?
Generally yes — good 4G coverage along most of the route. There are a few specific spots (inside long tunnels, deep parts of the Quirós branch) with weaker signal. We recommend downloading the map offline in Google Maps before setting off, just in case.
4. Is the map up to date?
Yes, as of April 2026. We review distances, car parks and points of interest every year. If you spot something that’s changed, drop us a line.
5. Can I plan the route on Google Maps?
Partially — Google Maps recognises the greenway as a cycle path but doesn’t have all the waypoints. For accurate planning, use Wikiloc, Komoot or our downloaded map.
