Fungus Rock

Boats anchor in the calm water that Fungus Rock itself shelters, in the lee of a 60m limestone islet standing at the mouth of Dwejra Bay. From there the dive forks into two routes. Stay inside the bay and the rock face runs 8 to 14m: boulders, small caverns and a shallow cave mouth, an easy circuit in flat water. Drop onto the open-sea side instead and the same rock turns vertical, dropping past 40m into open blue with fissures, gullies and swim-throughs cut into the wall. Sponge and red algae growth thickens noticeably below that line, colouring a stretch of wall the shallower bay side doesn't show at all. Divers chasing depth keep going. The face continues past 60m, and some push it further still on staged gas or rebreathers, a technical extension rather than the standard recreational dive. Few sites let a diver choose between a relaxed bay swim and a genuine deep wall from a single anchor point.

Fungus Rock earns its reputation on the choice it offers, not on a single headline feature. One diver rated it modestly at recreational depth and considerably higher once committed to the 60m range, and that split rating is the site in miniature: skip the wall and it's a pleasant but unremarkable bay dive, take the wall and it becomes one of Dwejra's more serious dives. Fish life runs thinner here than the dramatic rock face suggests. Grouper, octopus, amberjack, moray eels and dentex are all present, but divers who return here more than once describe the numbers as modest rather than abundant, so this is a site to visit for the terrain first and the fish second. The rock's name has its own small history. Its flat top once grew a parasitic plant harvested by the Knights Hospitaller as a wound remedy, and in 1746 Grand Master Manuel Pinto da Fonseca banned anyone from setting foot on it, posting a permanent guard to protect the supply. The plant isn't even a fungus. The name just stuck anyway.

This is a boat dive, launched from the sheltered water on the rock's inshore side rather than a shore entry. Independent divers need certification to 30m or a licensed instructor alongside them, a rule that matters here given how quickly the open-sea face runs past that depth. A 5mm wetsuit covers most of the season; bring a hood or vest for the boat ride, since surface winds pick up more than the sheltered water below suggests. Choose your route before you drop: the bay side rewards a relaxed pace over the boulders and cave mouth, while the wall rewards divers with the certification and gas planning to use it properly. There's no reason to push past your training to see what the deep wall offers. The 40m mark and its sponge growth are already a strong dive on their own. That's plenty for most divers.
