What you get on this adventure:
What’s not included:
GR20 is an advanced hike, meaning full day treks with steep descents and challenging switchbacks. Although it is becoming more and more popular, it remains one of the most difficult treks in Europe. To overlook this could put inexperienced walkers in danger. Do not overestimate your skills, and prepare for the trip. The GR20 is for hikers in very good physical shape who already have the experience of high mountain trekking over several days. Keep in mind, the weather in summer can be hot and you’ll also be packing a daypack filled with water and other things you’ll need throughout the day.
It is recommended to do aerobic exercises at least 3 times a week. It is good to get in some hill walks on rough, uneven terrain, to build up ankle strength. Train to walk downhill, get used to knowing where to put your feet. Aim to progress walking downhill at a reasonable pace — two walking poles will reduce the shock on your legs.
Here’s a list of the equipment you need to bring:
Dress comfortably and for the weather in clothes you can move in. We suggest bringing clothing appropriate for the season. Layers are best and don’t wear jeans.
Your guide will take care of your luggage transfers except on days 3 and 5. You only have to carry a daypack with your water, lunch, camera etc.
Group sizes and prices:
If your hiking party is larger than six people, please contact us prior to booking to make arrangements.
Min. age requirements:
If you plan to hike with anyone under the age of 12, please contact us prior to booking to make arrangements.
If the reservation takes place more than 30 days before departure, a 30% deposit to secure your place is due upon booking. The remaining amount is paid 1 month (30 days) prior to departure.

Thanks to new low-cost airlines, Corsica is now accessible from several major cities in France in less than 1.5 hours. To be as close as possible to the departure of the GR20, we advise you to go to Calvi (for the North) and Figari (for the South).
If possible, it is also wise to choose two different airports in Corsica for your GR20: if you start your hike in Calenzana, it is best to land in Calvi or Bastia. When you finish your hike in Conca, you should then choose Figari or Ajaccio Airport.
For the Standard GR20 Hiking Adventure, you will meet your guide in the morning of your first day in Ajaccio before transferring to the col de Bavella. For the Comfort GR20 Hiking Adventure, your trip will start in the morning of your first day from Calvi. The exact location will be determined in communication with your guide. From there, you’ll head straight to your tour. The guide will choose the appropriate terrain dependent on conditions and the hiking ability of the group.
