Choose the north if…
you are after a high-mountain atmosphere, are comfortable on rocky terrain and are in good physical shape. It is the most spectacular half, but also the toughest. See the GR20 North in 9 days.
Choose the south if…
you want to discover the GR20 with slightly less technical difficulty, enjoy varied scenery and have a week to spare. Be aware, though, that water is scarce on the ridges in summer. See the GR20 South in 7 days.
