Trip Highlights


Day 1: From Calenzana to Bonifatu

After meeting with your guides in Calenzana and going over the itinerary, explore the little village surrounded by olive trees and officially begin your GR20 adventure. Walk through the magical forests of Bonifatu, past magnificent viewpoints over the villages of the Balagne.

Walk: 4 hours
Altitude gain & loss: +800m, -540m

Day 2: From Bonifatu to Asco

Experience a change of scenery with the canyon of Spasmata and the little lake of Muvrella. Discover a mineral setting with an impressive volcanic mountain against the backdrop of turquoise waters of the Mediterranean. Just as you pass the Bocca di Stagnu, you’ll descend to the foot of the highest summit in Corsica located in the romantic valley of Asco.

Walk: 8 hours
Altitude gain & loss: +1300m, -598m

Day 3: From Ascu to Vallone

After a hearty breakfast, continue with your travels and cross the Great Barrier Reef passing by the Monte Cintu and through the Pointe des Éboulis. From Bocca Minuta, descend to the small valley of Straciaconne where you may have the chance to observe wildlife — especially mouflons, a type of wild sheep native to the Caspian region. Have dinner in a shepherd hut in Vallone, set up camp, and enjoy the starry skies with your group.

Walk: about 8 hours
Altitude gain & loss: +1200m, -800m

Day 4: From Vallone to Verghju

Your setting for the day is the valley of the Niolu located at the heart of the island. As you walk past the foot of the most beautiful summits in Corsica, the Paglia Orba and the strange Capu Tafunatu, use the numerous photo-ops and soak in the atmosphere. If the weather serves you, you can get a stunning viewpoint over the gulf of Porto before plunging into the small valley of the Golo. Enjoy the phenomenal views of a series of natural pools as you walk towards the forest and the Castel di Verghio. Spend the evening with your group at the gîte.

Walk: about 6 hours
Altitude gain & loss: +971m, -1017m

Day 5: From Verghju to A Sega

Your journey for the day begins between sea and sky with the crossing of Bocca San Pedru. The magic takes place once you cross the Bocca a Reta and see the jagged coastline plunging into the deep blue waters of the Mediterranean. On the opposite slope, a glacial crater conceals the lake of Ninu, a Corsican treasure nestled in a lush green setting. Bordered with pozzines (a type of bogs), the lake is also a sanctuary for wild horses, which can often be seen grazing peacefully around it. Follow a little stream until it becomes the great Tavignanu River and relax after a long day of hiking!

Walk: about 7 hours
Altitude gain & loss: +600m, -640m

Day 6: From A Sega to Corti

After a final dip in the natural pools around the refuge, continue alongside the Tavignanu River, in the shade of Lariccio pines. During the walk, there are plenty of opportunities for swimming in the river! At the end of the day, you arrive in Corti. Spend your final night in a hotel in Corti and explore the charming streets of the town.

How fit do I need to be?

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.

What do I need to bring?

Here’s a list of the equipment you need to bring:

    • Day pack large enough to carry items for a few days of hiking (around a 40L bag)
    • Duffle bag with all the remaining items and clothing (max. weight 15 kilos)
    • Trekking poles — optional (but recommended)
    • Headlamp
    • Compact sleeping bag
    • Sleeping pad
    • Water bottle or hydration bladder (2L capacity)
    • Snacks and electrolytes
    • Lightweight hiking boots or shoes
    • Sandals or flip flops for beaches, river wading, or for wearing in the evening
    • Hiking socks
    • T-shirt and shorts (depending upon the likely weather)
    • Light trekking trousers (not jeans)
    • Spare clothes for layering
    • A warm sweater, polar or fleece
    • Puffy jacket or equivalent mid-layer
    • A good quality waterproof shell — GORE-TEX recommended
    • Waterproof pants
    • Warm hat and gloves
    • Swimsuit
    • Sunhat
    • Beanie
    • Gloves
    • Toiletries (sunscreen, hand sanitizer, bug spray, toilet paper, etc.)
    • Camp towel
    • A small Tupperware box (for stews or salads), a plastic mug, a spork
    • A waterproof plastic pouch for documents and identity papers
    • A small first-aid kit
    • Swiss army knife
    • Sunglasses
    • Mobile phone and charger
