★★★★★★★★★★4.8 · 623 reviews · 4 hours · from $53

Set out from La Rochelle’s old harbor on a 16-meter sailing catamaran with a French captain and crew. Cross the bay, pass the Richelieu Tower and Les Minimes, then circle Fort Boyard. Bring a picnic, enjoy the trampolines, and ask the crew about the boat and local coast.

“We had booked earlier trip at midday on previous day but this was deferred due to weather. Our trip left dock at 19.30. Conditions were choppy and seating on catamaran is meagre. Do not recall any info called out re islands we passed. Crew handled navigation with skill and good humour, keenness to say a little in English not huge though.”
