All ten stages of the GR 92 between Portbou and Lloret de Mar are available here as a free download in GPX file format. The GPX file format is a standard file format for route information and waypoints. It can be opened, for example, with the Outdooractive smartphone map app we recommend (outdooractive.com/mobile-app.html). This free app is available for all popular smartphones (including Android and iOS).
Due to numerous inquiries, we have created instructions for the Outdooractive app. You can find them here: wanderndeluxe.de/outdooractive/.
We also offer PDF walking maps for the Costa Brava to download and print out yourself: PDF hiking maps at a scale of 1:20,000.
