About Plateau du four
Plateau du Four is an offshore rocky plateau off Le Croisic with drop-offs, varied relief, and rich marine life. It is best approached by boat with a local operator, especially when timing the dive around the tide and current window. The site is part of a larger shallow-plateau system with deeper edges, so the right plan is to pick a calm weather day, stick to the boat brief, and work the wall or ledge rather than expecting a casual shore hop.
