Inland Sea & Tunnel is a classic Dwejra shore dive: a sheltered lagoon linked to the open sea by a long tunnel, with easy shore entry and a dramatic outer exit. The lagoon is calm and scenic, but the tunnel and boat traffic make it a proper route dive rather than a simple swim-out.

Depth range, seasonality, and planning context.
Reported Depth
3m - 25m
Depth Note
Public guides place the lagoon-and-tunnel route between about 3 m and 25 m, with the tunnel beginning shallow and dropping toward the open sea.
Best Season
Year-round, but early starts and off-peak visits help avoid crowds and boat traffic.
Typical Conditions
Shallow lagoon, 80 m tunnel, cliff scenery, and a busy tourist/diver mix.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
The tunnel has direct surface access but still behaves like an overhead feature; keep control through the passage and watch for tour boats overhead.
Access Restrictions
Shore entry from the Inland Sea slip-way is easy, but the site is tourist-heavy and boat traffic is part of the experience.
Legal Notes
No special permit is indicated; follow normal shore and marine rules and plan around tourist boat movement.
Community notes to help plan your visit.
Scuba Diving
The lagoon-to-sea tunnel route is a classic scenic scuba dive, with easy lagoon entry and a more dramatic outer section.
Freediving
The sheltered lagoon can work for freedive practice in calm conditions, but the tunnel and boat traffic make it better suited to controlled scuba.
Snorkeling
The lagoon can be snorkeled in calm water, but the tunnel and passing boats mean the site is better treated as a proper dive objective.
