Prepare
Leaving the GR20 early
"What if I can't make it? If I get injured, how do I get out?" It's the number-one worry before setting off — and a fair one, because nearly one hiker in two doesn't finish. Here, from north to south, are the places where you can leave the trail and how to reach a road or a station. Bailing out is neither a failure nor a disgrace: sometimes it's the soundest call.
The context
Neither a failure nor a disgrace
It's easy to forget: the GR20 has a high drop-out rate. According to the estimates that circulate, 40 to 50% of hikers don't finish, many of them in the first few days, before Vizzavona (the figure isn't official, but it says something real). The causes are almost always the same: blisters, accumulated fatigue, the weather, or a small injury that gets worse.
The real mistake isn't giving up: it's pushing on one day too many. A managed exit beats an emergency rescue. Knowing where and how to leave the trail is precisely what lets you walk with a clear head — and often go further than you thought you would.
The rule
Scout your exits in advance
Before you go, map out the points on your route where you can reach a road. You may never need them, but simply knowing they're there takes away the anxiety and lets you decide calmly when the time comes. And on the ground, the best reflex is the same as for everything else: ask the gardien about the local options (shuttle, taxi, nearest road).
Exit points
Where to leave the trail, north to south
The GR20 doesn't offer many escape routes — that's part of its reputation — but there's one at each main section. The principal ones, north to south:
North — Haut-Asco
From the Asco resort (Ascu Stagnu), reachable by road, a bus runs to Ponte-Leccia and its station. The classic northern exit.
North — Castel di Vergio
At the Col de Vergio (D84 road), a shuttle/bus drops down to Albertacce then Corte. Handy coming out of the Cintu stages.
Centre — Bergeries de Grotelle
A descent through the Restonica valley reaches the road, then Corte. A useful escape around Manganu / Petra Piana.
Centre — Vizzavona
The simplest exit on the whole GR20: a CFC railway station on the Bastia–Ajaccio line (see below).
South — E Capannelle
The D169 road reaches Ghisoni. The first real way out of the southern half.
South — Col de Verde & Bavella
At the Col de Verde (D69, towards Cozzano/Ghisoni) and above all the Col de Bavella (D268), you reach the road, then Solenzara and the coast.
[Timetables and fares of local buses vary by season — check before relying on them.]
The prime exit
Vizzavona, at the halfway point
If you remember just one point, make it this one. Vizzavona cuts the GR20 in two and has a railway station on the Corsican railway (CFC) Bastia–Ajaccio line. From there, trains run to Ajaccio (~1 h), Bastia (~2 h 40) or Calvi (~4 h 30, changing at Ponte-Leccia).
It's the logical cut-off point to finish, take a break, or head home without drama — and also the way to do the GR20 in two halves. [CFC timetables to be checked on train-corse.com before relying on them.]
Deciding
When, and how, to get out
Listen to your body and the sky. An injury that's settling in, a storm forecast over an exposed stage, low morale over several days: all signs that cutting it short is wiser. Talk to the gardien the evening before — they know the local exit options best.
And in a real emergency (serious injury, immediate danger), you don't improvise your own evacuation: the reflex is 112. It's all set out on our safety page.

Services (buses, shuttles) change every season; so do the Corsican railway timetables. For freshness, rely on the Corsican railway (CFC) (train-corse.com), on the refuge gardiens and on the local tourist offices. The 40-50% drop-out rate is a widely shared estimate, not an official figure.
