May 2019
On 4th May the Refuge d'Ortu di u Piobbu was burnt to the ground,
possibly deliberately. While the camping area and water supply are
unaffected, there will definitely be no indoor accommodation available
during 2019. A temporary shelter will be in place to offer meals, and
the camping area and water supply are unaffected. Work might start very
soon on rebuilding the refuge, and bear in mind that the Refuge de
Carrozzu, next in line along the GR20, might be rebuilt shortly too,
along with the Refuge d'Asinau, towards the end of the GR20. Remember
that a low-level route allows trekkers to omit the Refuge d'Ortu di u
Piobbu, linking Calenzana directly with the Refuge de Carrozzu in one
day. Full details are in the guidebook.

Website Changes
The PNRC has changed its website address and has also launched a new online booking system for the refuges and campsites. The PNRC website is now www.pnr.corsica and the booking website is now reserver.sitecresa.fr/centraleresa/parcnaturel. It is also worthwhile clicking on the link titled 'punaises de lit information randonneurs', which explains all about the ongoing bedbug infestation in the refuges. To discuss the trail with other users, see corsica.forhikers.com/forum.
Reconstruction of Refuges
A major project will start during 2018, where the basic GR20 refuges will be reconstructed, expanded and improved. This will probably take place at the rate of two or three refuges per year. While building work is taking place at refuges, accommodation is likely to be available in large, military-style tents. All other services, such as camping places, meals and the sale of food and drink will be unaffected.
