A weekend at the Port Man fort on the magnificent island of Port Cros With family or friends, come and enjoy a moment out of time at Yann Arthus Bertrand's home, where you'll be given the keys to the fort he rents from the French government, nestled in the most unspoilt and wild of the Golden Isles: the island of Port-Cros (Var). A former French military structure that has been renovated to the highest standards, the Fort de Port Man can accommodate up to 8 guests. Part of Europe's first national marine park (1963), the 7km² island is a veritable sanctuary for endemic flora and fauna. Come and enjoy its crystal-clear waters, teeming with aquatic life, and hikes far from the hustle and bustle of the city. Transport and meals are not included in this package. Dates for this 3-day, 2-night weekend (Friday and Saturday evening) are to be arranged outside school vacations, subject to availability at the Fort.
