Inland Sea Tunnel

The Inland Sea is a pebble-ringed lagoon sealed off by Gozo's cliffs, connected to open water only through a narrow slot a boat's width across, and divers ride that geology like a corridor into another world. The tunnel runs about 80 m, deepening as it goes, its final frame a burning blue rectangle that ranks among diving's great doorways. Outside, walls drop past 40 m into cobalt water where amberjack and dentex sometimes patrol. The return swim aims back at a keyhole of daylight. Timed between tour boats and swell, it is a short dive that stays in memory for years.

Momen yang Anda nantikan: The 80 m tunnel, the blue exit frame, big walls beyond the cliff

Topografi: An 80-meter natural tunnel through the cliff, floor stepping from lagoon shallows down to about 26 m at the sea exit, opening onto steep walls

Entri: Enter the shallow lagoon by the fishermen's boat huts at Dwejra and follow the tunnel seaward: small tour boats use the same passage, so depth discipline and listening for engines matter.

Bahaya: Boat traffic in the tunnel overhead, darkness mid-passage, and swell funneling through in unsettled weather.

Konservasi: Shared, protected space at Dwejra: give the tour boats the surface layer and the tunnel walls their fragile growth.
