The trail is open again

Good news for anyone with a northern GR20 crossing this summer: the trail has reopened. The Haute-Corse fire and rescue service declared the Albertacce fire *fixé* (contained) at around 300 hectares, and on 23 July the authorities lifted the ban on the GR20 between the Asco and Ciottulu di i Mori refuges. The two stages that had been shut in both directions — Asco to Tighjettu, and Tighjettu to Ciottulu di i Mori — are walkable again.

The fire, sparked by lightning on 10 July above Albertacce in the Niolu, had closed this stretch for nearly two weeks at the height of the season and forced the evacuation of the Bergerie de Ballone and the Tighjettu wardens.

What to expect on the ground

The fire is out of its active phase but still under surveillance — crews stayed on site to treat residual hot spots after the reopening. Expect visible burn scars along the section, and don't be surprised by a lingering smell of smoke or the odd patch of blackened maquis near the path.

Nothing about a reopening removes the underlying summer fire risk. Corsica burns most years in July and August, and a closure can reappear at short notice if conditions turn.

Our planner shows live refuge availability and a weather briefing for exactly this kind of fast-moving situation — but it's a companion to the official channels, not a replacement. When in doubt, check both and don't improvise around a closure.
