Be honest — the GR20 is Europe's toughest marked trail. Your level sets a realistic pace and daily hours.
You can change this later in ⚙ settings.
Which part will you take on?
The full crossing is the classic — but each half is a great trek in its own right.
Direction
Most hikers walk North → South — the classic way.
How much time do you have?
Walking days only — you can fine-tune stages and add rest days in the planner.
One last thing — maps
There's barely any signal up there. Download the topo maps now (~30 MB, best on Wi-Fi) and navigation works the whole way.
