Inland Sea Tunnel (Dwejra)

A shallow inland lagoon connects to the open Mediterranean through an 80m tunnel bored through the cliff. Divers swim the tunnel in shallow water, then emerge on a wall that drops past 30m. The light through the passage is the appeal; watch for the small ferry boats that use the same channel.
