Also known as: Wied iż-Żurrieq, Zurrieq Valley
A shared SW Malta fishing quay with a sheltered training valley, a 30m wall, named sea caves, and the shore route to the Um El Faroud tanker.

A dive here starts with a choice. Down the concrete quay, the first decision is which of the site's parts you're doing that day. Head west and the terrain breaks into drop-offs, ledges, gullies and boulders before opening into Bell Tower Cave, a bell-shaped chamber with three entrances bottoming out around 27m, where resident cardinalfish hold station in the gloom. A tighter neighbour, Mouse Hole Cave, sits nearby at about 25m. Head east instead and the profile turns into a straight wall, dropping past 30m with some of the better visibility on this stretch of coast. A third option runs past a submerged diving-helmet statue on the sand, a marker on the long shore swim out to the Um El Faroud tanker, whose own story sits on its own page. Whichever route gets chosen, the return always comes back to the same small inlet, where ladder conditions and boat traffic matter as much as anything seen underwater.
No other Malta shore point packs quite this much in. A shallow training valley, a 30m wall, two named caves, and a swim to the island's single most-requested wreck all share the same four ladders and one slipway. Cirkewwa runs a similar idea further north, but its draw is a natural arch and a statue; here the caves themselves are the local landmark, catalogued and named rather than generic swim-throughs. The trade-off is obvious on arrival. This is a fishing harbour first, a dive site second: traditional boats and tourist luzzus share the same small bay, parking is informal and scarce, and the quay itself is genuinely crowded through summer. Divers who rate the site highly tend to rate the caves and the wreck access in the same breath, treating them as one package rather than separate reasons to visit.
Above the water, Sciuta Tower has watched over this bay since 1638, built for the Knights of St John as the prototype for what later became Malta's wider chain of coastal watchtowers. Below it sits a newer marker entirely: a full-size brass diving-helmet statue, placed on the sand at around 28m on 3 July 2005 by a local dive club marking its fiftieth anniversary. It has since become a landmark in its own right along the route out to the Um El Faroud, more a photo stop than a monument with any deeper story attached. Neither belongs to the wreck. The tower predates diving here by more than three centuries, and the statue is a club's own tribute rather than a wartime relic, which makes this stretch of coast one of the few in Malta where the history above the water and the history below it come from entirely different centuries.
Check the ladders first. Storms can dislodge them, especially outside summer, and the slipway becomes the only way out if that happens. The quay surface itself is fully concreted and can turn slippery with algal growth, especially near the slipway. A surface marker buoy earns its keep here, mainly on the east side, where tourist boats crossing to the actual Blue Grotto add regular surface traffic. Currents can build up inside the inlet even when the surface looks calm, so it pays not to assume shelter just because the bay looks sheltered on the surface. Anglers fish from the rocks around the entry; give their lines room on the way in. Bring a torch for both caves, and arrive early if diving in summer: informal parking at the bottom of the hill fills fast, and the official car parks sit 150-200m further out.
What makes this dive site stand out.
Four ladders, a ramp and a slipway serve a busy shared inlet, not a single feature
Three entrances, bottoms around 27m, a bell-shaped chamber with resident cardinalfish
Named for its narrow entrance, around 25m
Drops past 30m with strong visibility on most accounts
A marked swim past a submerged diving-helmet statue reaches Malta's biggest wreck
35.8197°N, 14.4514°E
Summary
The Valley itself is easy and used for training and night dives; West Reef & Caves and the East Reef wall run deeper and call for more experience.

Not quite. Divers use the name colloquially for this shore hub, but the actual tourist Blue Grotto sea cave sits about a kilometre east and is normally seen by boat, not dived. This site has its own separate 'Blue Grotto Caves' component, reached by boat or a long swim, which is a different thing again.
There is a Blue Grotto Caves component within this site's own dive area, shallow but exposed to swell and reached by boat or roughly a 40-minute swim from the Valley entry. It is a distinct feature from the tourist boat-trip landmark a kilometre east, which is not usually dived.
By a shore swim from the same quay, passing a full-size brass diving-helmet statue on the sand along the way. The statue was placed at around 28m by a local dive club on 3 July 2005 and now serves as a landmark and photo stop in its own right on the route out.
Bell Tower Cave, a bell-shaped chamber with three entrances bottoming out around 27m and home to resident cardinalfish, and Mouse Hole Cave, named for its narrow entrance, at around 25m. Both sit within the West Reef & Caves section of the site.
The Valley is, and it is used regularly for training and night dives within Open Water limits. East Reef and West Reef & Caves reach 27-30m and call for Advanced Open Water, and the same level applies to the swim out to Um El Faroud.
No formal marine reserve applies to this inlet. Natura 2000 conservation areas exist nearby along the same coast, but an official assessment places this specific site outside their boundary, and no permit or fee applies here.
Wied iz-Zurrieq is one of Malta's two busiest shore-dive hubs, and it also hosts the tourist boats running to the actual Blue Grotto landmark. Parking is informal and fills fast, so arriving early in summer makes a real difference.
