How to get to the GR10 and back
Travel to and from shorter sections of the GR10 are available on the pages where those sections are discussed. This page contains general information about (public) transportation in, from, and to the GR10 in the French Pyrenees. I will tell you how to get to Hendaye and from Banyuls-sur-mer, the start and finish of the GR10.
Cars are the main mode of transportation used by the French, and therefore the most effective within France. If you travel by car, use the navigation app you have on your phone. The rest of this page is about public transportation in the Pyrenees. If you travel by car and do all or a section of the GR10, you still need to travel back to your car, probably using public transportation.
Public transportation in the Pyrenees
Public transportation around the GR10 is okay as long as you can use trains. Good planning is required for smaller towns that only have bus connections. For some sections of the GR10, there is just one connection per day or less. The busses and trains are air conditioned and have comfortable seats.
for short sections if you feel okay to do so, because it can save time.
