Display the route on Google maps

Map display. Initially the route will appear on Google Maps.
Once the page is open (assuming a network is available, of course), click the symbol in the top right corner of the map. You will instantly see your location (blue dot ) on or close to the hiking trail. 
Markers. Similar to a simplified road book, the map’s markers (yellow pins), provide information and directions for the route. The content will show up when you click on them.

Free download

You may also download the map in GPX or KML format and display it in the language of your choice (English, French, or Greek), either in Google Maps or in a similar application that does not require data or access to a telephone network, such as Garmin Explore, Gaia Gps, etc. In this case, make sure to download the map to the selected application before leaving a location with internet connection.
The number of routes you can free download depends on how many days you stay at the campsite. You are entitled to one free of charge route for each day of stay.

Offline GPS applications

For your convenience, here are some links to download helpful apps that don’t require data or internet connection:
Garmin Explore | All Trails | Geo Tracker | Gaia GPS
The Gaia Gps and All Trails apps are also compatible with PCs, so you can edit the route directly on your computer. For those who are not as familiar with Gps apps, All Trails and Geo Tracker options are simpler to use.
