From Vizzavona to Asco, your physical condition will be put to the test and for that you must prepare yourself well before you venture out to avoid any inconvenience or possibly complicated situation.
Once you are well equipped to cross the highest mountain passes, your journey takes you past glacial lakes before crossing the famous and aptly named "cirque de la Solitude" (cirque of Loneliness).
The GR20 is an authentic route that crosses all of Corsica on 200 kilometres, from the northwest to the southeast, along the coastline. Mountains and sea, lakes and peaks, they all come up at some point on the way. A variety of trails, stays and hikes, training sessions and intensive sporting preparations are all available, with or without local professionals to guide you. It is possible to build your activity list depending on your capabilities and activities of choice, and therefore discover on foot local fauna and flora in all their richness.
