Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.
The dive
A straight tunnel runs through the cliff from the lagoon to the open sea, with daylight from both ends. Outside are sheer walls, and visibility there is often >30 m.
Profile and sections
A straight tunnel runs through the cliff from the lagoon to the open sea, with daylight from both ends. Outside are sheer walls, and visibility there is often >30 m. The dive can be combined with Tal-Barba (north) or towards the Blue Hole (south).
Practical: this is one of Dwejra's most sheltered sites; only strong W/NW wind rules it out.
- Depth and profile
- Lagoon -2 m; tunnel ~80 m, floor sloping from -3/-6 m to ~-26 m at the sea end; outside, walls to -35/-50 m and deeper
- Configuration
- All configurations
- DPV: DPV possible
- Not needed for the tunnel itself, but handy to reach Tal-Barba (~200 m north) from here.
Who can dive where
- At least Open water / no overhead
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 26 m (trimix or deco may be needed)
This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
Shore: park at the Inland Sea, kit up at the car, a few steps and wade in over pebbles into the lagoon (max -2 m).
