For me, Inland Sea is the cherry on top of the cake after the Blue Hole. It is close enough to be part of the same diving day, yet the feeling could hardly be more different.
Site at a glance
From enclosed lagoon to open Mediterranean
The dive begins in a shallow inland lagoon surrounded by rock and buildings. Ahead is a dark opening. The tunnel is roughly eighty metres long and connects the Inland Sea directly with the open Mediterranean. As you move through it, the blue at the far end grows brighter until the entire seaward wall seems to disappear.
That transition — from an enclosed, almost quiet basin to a huge open wall — is the reason I never get bored of it. The tunnel is not just the way to the dive. It is part of the dive.
Getting in
Access is from the Inland Sea at Dwejra. Compared with the Blue Hole, carrying equipment to the water is straightforward. The lagoon is shallow and makes kitting up and descending relatively civilised. The important part begins before entering the tunnel: this is also a route used by tourist boats.
Boat traffic is the defining practical consideration. I do not treat the tunnel as a place to drift casually near the surface. Depth, position, lights, team awareness and listening for engines all matter.
Outside the tunnel
The seaward exit opens onto a steep wall with considerably more depth available than most recreational divers need. This lets different teams make very different dives from the same starting point. You can keep the profile moderate and enjoy the wall, or plan a deeper dive when training, gas and objectives support it.
The return through the tunnel is just as impressive. The light is reversed, the Inland Sea becomes the bright end point, and the feeling of moving back into the island is completely different from the outward journey.
Blue Hole plus Inland Sea
I particularly like these sites as a pair on the same day. The Blue Hole is complex, sculpted and full of changes in direction. Inland Sea is simpler in concept but enormous in visual impact. One feels like exploring a stone labyrinth; the other feels like travelling through the island and emerging onto a vertical blue world.
There are one-way routes in the Dwejra area, but they require deliberate logistics and should never be improvised just because two sites look close on a map.
BusaBoy note
The first time the blue exit fills your field of view, it is easy to understand why this is one of Gozo's signature dives. Doing it after the Blue Hole is almost unfair: Dwejra gives you two completely different highlights within a few minutes of each other.
