Île Longue

You're anchoring off one of France's most secretive spots — Île Longue is home to France's nuclear submarine base, the homeport of its entire ballistic missile fleet, so expect restricted zones and military presence that make this a genuinely unusual anchorage. The peninsula juts out from the Crozon into the Rade de Brest, and the sense of being at the edge of Europe, with vast Atlantic skies and wild Finistère scenery around you, is hard to beat. Keep your distance from the base perimeter and enjoy the dramatic setting from the water.
