Free, snorkel-only, and utterly unexpected in the middle of France's second city. Opened 2020 as France's first underwater museum, deliberately sited within swimming distance of a public beach to make sunken art free and democratic rather than dive-ticketed. Anchorage: Anchor off the Catalans / Frioul islands; tender in to 100m off the beach. Hazards: No site-specific hazards noted, brief normally. Plus
