Trek the GR20 in Corsica: Self-Launched Northern Half
8 days · Corsica, France
Much Better Adventures charges £1,395
No-markup version: ~£475 per person
Estimate only, not a guaranteed price. Always verify costs independently before booking.
Tackle the northern half of Europe's toughest long-distance trek independently — from Vizzavona to Bonifatu along the spine of Corsica's dramatic mountain interior. This self-launched version follows the exact same GR20 route, swapping the guided group for your own pace, pre-booked refuges and campsites, and local transport connections. All meals on trail are budget-friendly; the biggest savings come from cutting the group operator premium entirely. This is a serious undertaking — only attempt independently if you have solid mountain trekking experience, good navigation skills, and fitness to match 6 consecutive days of hard hiking at altitude.
Day-by-day
Arrive in Corsica & transfer to Vizzavona
Bastia → Vizzavona
Fly into Bastia-Poretta Airport (BIA). From the airport, take the regional train (Line 1) to Bastia station (~€13, 30 min), then board the Chemins de Fer de la Corse (CFC) train from Bastia to Vizzavona — a scenic mountain railway journey of around 2.5 hours costing roughly €15–18. Alternatively, a shared taxi or rideshare from Bastia to Vizzavona can be arranged for ~€40–50 split between trekkers. Check in to the Gîte I Laricci or similar guesthouse accommodation in Vizzavona forest. Study your GR20 topo map, confirm your refuge bookings for the days ahead, and get an early night.

Vizzavona to Petra Piana — the GR20 begins
Vizzavona → Petra Piana
The northern GR20 kicks off with one of its longest and hardest stages — 15.5km, ~9.5 hours, with 1820m of ascent. Set off early from Vizzavona, ascending past the Cascade des Anglais to the Brèche de Muratellu at 2100m. Ridge-walk via the summit of Pinzi Corbini — steep, exposed, and exhilarating. In poor weather, take the lower valley variant via Tolla and the Cascades sur le Manganelo. Arrive at Petra Piana refuge by late afternoon. Refuges on the GR20 must be booked in advance via the PNRC (Parc Naturel Régional de Corse) website or directly — dorm beds cost ~€15–20pp, camping at the refuge ~€8–10pp. The refuge bar serves cold drinks; take dinner at the refuge (~€18–22 for a set meal).

Petra Piana to Manganu — lunar landscapes and ridge views
Petra Piana → Manganu (Camputile Plateau)
A shorter but technical day (8.5km, ~5.5hrs, 780m ascent). Head up to the high ridge above Petra Piana refuge, weaving through a rocky, otherworldly landscape with chain-assisted sections — poles and sure footing essential. Pass above Lac de Capitello with views of the Rotundu massif to the east and the Mediterranean glittering to the west. Drop down to Manganu refuge on the edge of the Camputile Plateau. Pre-book your camping pitch or dorm here too. The refuge serves hearty evening meals — budget ~€18–22 for dinner.

Manganu to Col de Vergio — Lac de Nino and the ski station
Manganu → Col de Vergio (Castel di Vergio)
A longer but more gentle day (16km, ~6.5hrs, only 540m ascent). The highlight is Lac de Nino at 1743m — a stunning glacial lake surrounded by peat moorland grazed by wild ponies. Take a proper break here before pushing on down to Col St Pierre and following the horseshoe trail to Castel di Vergio, Corsica's small ski station. The refuge here has dorm accommodation and a bar — treat yourself to a cold Pietra beer. You're at the midpoint of your northern GR20 traverse. Note: if you've arranged a luggage drop, Col de Vergio is one of the few road-accessible points on the route.

🛏Castel di Vergio Refuge — dorm bed ~£18–22

Col de Vergio to U Vallone — forests, rivers and high ridges
Col de Vergio → U Vallone Refuge (Mélarie Valley)
A varied 14.5km day (~6.5hrs, 810m ascent) that begins with a long, rolling traverse through the beautiful Valdu Niellu forest alongside the Golo River. Natural pools in the river make for a refreshing mid-morning dip. The trail climbs steeply from the valley floor to the ridge, rewarding you with views of the west coast villages and distant Mediterranean islands. Pass the high Ciuttolu di I Mori refuge at 2000m (the highest on the GR20, wedged between Tafanatu and Paglia Orba). Continue down to U Vallone refuge for the night. Pre-book all refuges well in advance — the GR20 is increasingly popular in July and August.

U Vallone to Haut-Asco — the GR20 at its highest
U Vallone → Haut-Asco
The most demanding day of the trek (9km, ~8hrs, 1260m ascent). A slow, steep and rocky climb towards the flanks of Monte Cinto (2706m), Corsica's highest peak. Reach Bocca Crucetta before traversing to Pointe des Eboulis at 2607m — the highest point on the entire GR20. Snowpack can linger here into July. The descent from Pointe des Eboulis is precipitous, with scree and rocky terrain eventually giving way to a river and forest as you approach Haut-Asco, the old ski station. The Haut-Asco refuge has dorm beds and a bar — you've earned that cold drink. This is one of the great alpine days in Europe. Second road-accessible point, so arrange any additional luggage here if needed.

Haut-Asco to Bonifatu — the final stage
Haut-Asco → Bonifatu → Calvi
The triumphant final stage (11km, ~7hrs, 690m ascent, 1600m descent). Climb to Bocca di Stagnu at 2150m beneath Muvrella, where the Bay of Calvi suddenly comes into view — one of the most beautiful moments on the entire trek. Descend via Muvrella Lake, cross the iconic Spasimata footbridge, pass Carozzu refuge (good for a snack stop), and make the long, demanding final descent along the Mare e Monti trail to Bonifatu. From Bonifatu, arrange a taxi or bus connection to Calvi (~30 min, €20–30 by taxi). Treat yourself to a budget hotel or hostel in Calvi — Hôtel du Centre or similar — and head out for dinner at a Calvi restaurant to celebrate completing the GR20 north.

Depart Corsica — Calvi to Bastia Airport

To reach Bastia Airport, take the scenic CFC train from Calvi to Ponte-Leccia (~1.5hrs, ~€10), then change for the Bastia train (~1hr, ~€5). Total journey around 3 hours — book the earliest suitable train to make a midday airport arrival for afternoon flights. Alternatively, a shared taxi or Blablacar from Calvi to Bastia runs ~€25–35.

Frequently asked questions
How much does Trek the GR20 in Corsica: Self-Launched Northern Half cost?+
Doing it yourself with this self-launched itinerary costs an estimated £475 per person for 8 days in Corsica, France. This is an AI-generated estimate based on typical budget-traveller prices — actual costs will vary by season and how you book.
Is this cheaper than booking with Much Better Adventures?+
Yes — Much Better Adventures charges around £1,395 per person for a similar tour. Doing the same route independently, using the same standard of accommodation and activities, costs an estimated £475 — a saving of roughly £920 (66%) per person.
How long is the Corsica, France trip?+
This itinerary runs 8 days, covering 8 day-by-day stops through Corsica, France.
How do I join this trip?+
You can join an existing open departure using this itinerary if one is scheduled, or launch your own departure with your own dates and invite other travellers to join you — no tour operator required.
Isn't it easier to just use a tour operator?+
Well, yes, a tour operator will book all the individual parts of your travel for you and provide a guide. That's obvious, but doing this has the potential to save the group thousands, which can in turn improve your itinerary substantially or save you huge amounts of money. Also, when you launch a departure, Travel Crew has tools in place to help you book the individual sections of the trip or make it easier for you to do this as a group. Really, you do not need a middle man. If you are more comfortable paying more and using a middle man, then you should certainly do this.
Is it safer to book through a tour operator?+
Arguably, there isn't much difference. A self-launched trip runs on the same principle as a group travel crew: collective responsibility, everyone looking out for each other, the same way it would if a group of friends organised the trip themselves — because that's exactly what's happening. You should always take out travel insurance before you go, self-launched or not; that doesn't change either way. Every open departure is published publicly with real dates and a real trip organiser, so it's never an anonymous arrangement, and our support team is reachable any time you need help, including in an emergency while you're away. Longer-term, we're building direct relationships with ground DMCs in popular destinations, offered as an optional paid add-on for extra on-the-ground support. Ultimately, though, the group is responsible for its own conduct and safety on a self-launched trip, same as on any trip you plan yourself.
What kind of trip is this?+
This is a hiking, adventure, backpacker trip through Corsica, France, self-launched rather than run by a tour operator — you organise it with a group you find or bring yourself.
