4) GR20, Corsica

For those who require a little less pampering than the rest, the GR20 in Corsica offers a hiking experience unlike any other. Whether you choose to use the mountain huts in route or not, with 111 miles (180km) of trail to cover, you will need to be largely self-sufficient, and prepared for a true test of your endurance and navigation skills. Beyond the challenge, the scenery is outstanding, with lofty mountains, waterfalls, alpine wild flowers and wildlife and also views of the sea from every pass, cliff and peak. If wild and adventurous is your thing, the GR20 won’t disappoint.
