Għar id-Dar

The famous House Cave on the Wied ir-Raħeb wall: a door cut into the cliff, a round window above it for the exit, and a black chimney at the back that surfaces in a sealed pocket of air. Strange, theatrical and very quiet.

Exposed to wind and swell from: W (270°), NW (315°), SW (225°). West coast, so the same rules as Dwejra apply: flat in an easterly, off the menu in anything westerly. The caves amplify swell, so what feels like harmless movement on the surface becomes a proper push inside. Best season: Late May to October, when the west coast settles and the boats run reliably..

The dive

Wied ir-Raħeb is a dry gorge that runs several hundred metres inland and finishes abruptly in a cliff face about twenty-five metres above the sea. Dive centres usually work the wall below it as a drift, taking in three separate caves along the way, and Għar id-Dar is the one everybody remembers. Its entrance is so squarely cut that the name simply gives up and calls it a house: a doorway in the rock, with a neat round window set above it that you use as the way out.

Inside, the cave opens up and darkens. At the back a wide chimney climbs into total blackness, and if you follow it with a torch you surface in a small trapped pocket of air with the cliff pressing in on all sides. It is the kind of place that either delights you or makes you want to be somewhere with a horizon, and there is no shame in either reaction. Come back down, swing out through the window, and the contrast is the best part of the whole dive: from a lightless shaft to blazing blue in about three fin kicks.

The other two caves on the run are open to the sky, at roughly fifteen and twenty-five metres, and their walls and floors are carpeted with coloured sponges and calcified growth. Fish life along this wall is modest by Gozo standards, so bring a torch and an appetite for rock rather than a camera set up for shoals. The boulder slopes between the caves are enormous and make the scale easy to misjudge.

Typical plan

Drop at the northern end of the wall and drift south at 15 to 20 metres, taking the first open cavern as you pass. Enter the House Cave through the door at around 12 metres, work back to the chimney with torches and a line sense, put your head into the air pocket for a moment, then come out through the window. Continue the drift to the third cavern at 25 metres and finish shallow along the wall with a stop at 5 metres before the boat picks you up. Forty-five to fifty minutes, air or nitrox 32, two torches each and no more than two divers in the chimney at a time.

Massive tumbled boulders on bare limestone, with fine silt and shell debris settling on the floors inside the caves.

Who you might meet

Getting in and staying safe

Boat only. The cliff here is unbroken and there is no way in or out from land, so you go with a charter from Mġarr, Xlendi or the north coast, usually as part of a west coast trip that also takes in Wied il-Mielaħ or Dwejra. Dives are often run as a one-way drift with the boat following, which means a good SMB and a skipper who is paying attention. There are no facilities anywhere near, and no shelter if the weather turns.

Genuine overhead environment in the chimney and at the back of the cave
The air pocket is a sealed void of unknown quality, so do not linger and do not breathe it deliberately
Silt and fine sediment inside the cave, easily stirred into a whiteout
Surge through the door and window entrances when there is any swell
Boat-only access with no shore bail-out along this cliff
Torch failure turns a pleasant cave into a serious problem, so carry two
The wall outside drops well past recreational depths

A bit of history

Nothing dramatic happened here, which is part of the charm. Wied ir-Raħeb translates roughly as the hermit's or the sacristan's valley, one of a string of gorges that drain Gozo's western plateau and end in sheer cliff. The caves are sea-cut features in Lower Coralline limestone, opened along joints and bedding planes by wave action over a very long time; the chimney in Għar id-Dar is a joint that the sea has worked upward until it broke into an air-filled void. Local fishermen know the House Cave as Ta' Wiereb, a name that predates any diver ever seeing the inside of it.
