Ghar Dalam – "Cave of Darkness" in Maltese – holds bones of dwarf elephants, hippos, bears and deer preserved in sediment since the last ice age, some dating back 500,000 years. The cave is 144 metres long with the first 50 metres open to visitors, plus an on-site museum displaying excavated bones including a dwarf elephant skull. It sits near Birzebbuga in south Malta and takes about an hour to see properly.
- 01Ghar Dalam contains bones of ice-age animals – dwarf elephants, hippos, bears and deer – dating back up to 500,000 years, making it one of Malta's most significant prehistoric sites.
- 02The cave is 144 metres long; the first 50 metres are accessible to visitors, with the sediment layers still visible in the walls.
- 03A small on-site museum displays the actual bones excavated from the cave, including a dwarf elephant skull.
- 04It pairs naturally with Ħaġar Qim and Mnajdra on a south Malta day – the temples are about 15 minutes away by car.
- 05The site is rarely crowded compared to the Ħaġar Qim complex, making early visits especially peaceful.
What is Ghar Dalam?
The name translates as "Cave of Darkness" and refers to a natural cave carved by an underground river long before humans arrived on Malta. Over hundreds of thousands of years, animals crossing a land bridge that once connected Malta to Sicily and mainland Italy fell into the cave or sheltered there, and their bones accumulated in thick sediment layers.
Excavations beginning in the 19th century uncovered remains of species that have been extinct in Malta for millennia: dwarf elephants (a smaller island-adapted species), dwarf hippopotamuses, brown bears, wolves, foxes and several species of deer. The oldest bones date to around 500,000 years ago.
The cave also contains evidence of Malta's earliest known human inhabitants. Pottery sherds and animal bones showing signs of human activity have been found in the upper sediment layers, dating to around 7,400 years ago – the Neolithic people who later built the megalithic temples.
The cave
The first 50 metres of the cave are open, lit and walkable along a narrow path. The sediment layers are visible in cross-section on the cave walls – a visible geological record of different periods, labelled to show which animals were found in which stratum.
The cave itself is not dramatic in the way that stalactite caves in other countries can be. It is a straight, dimly lit rock tunnel with exposed earth walls. What makes it interesting is context: knowing that you are looking at undisturbed geological layers containing bones from half a million years of animal life concentrated in one place.
The temperature inside is noticeably cooler than outside, which is a relief in summer. A light layer is worth carrying even in July.
The museum
The on-site museum is small but well laid out. The main exhibits are the actual bones excavated from the cave: a dwarf elephant skull is the centrepiece, alongside hippo teeth, deer antlers and smaller mammal remains. Labels are in English and Maltese.
The museum also has a display on the Neolithic human presence at the site, connecting Ghar Dalam to the temple-building culture that produced Ħaġar Qim and the other megalithic temples. For anyone following a south Malta prehistoric day, this context is useful before heading to the temples themselves.
Allow 20–30 minutes for the museum before entering the cave.
How to get to Ghar Dalam
By car, Ghar Dalam is about 25 minutes from Valletta via the road south through Marsaxlokk or through Birzebbuga. There is free parking directly at the site entrance.
Public transport options exist but are limited – check the Malta Public Transport app for current routes to Birzebbuga. For most visitors, the practical approach is a car or a guided tour that combines the cave with Ħaġar Qim and Mnajdra.
Ghar Dalam as part of a south Malta day
The cave sits roughly halfway between Marsaxlokk harbour to the east and the Ħaġar Qim temples to the west – a natural anchor for a south Malta day. A practical order: start at Ghar Dalam when it opens at 09:00, drive 15 minutes to the Ħaġar Qim and Mnajdra temples for mid-morning, then continue to the Blue Grotto for a boat trip and lunch before the afternoon crowds arrive.
Alternatively, pair Ghar Dalam with Marsaxlokk to the east – the fishing village is 10 minutes away and the Sunday market makes a natural end point to the morning.
For a broader overview of Malta's prehistoric sites, including the Ħal Saflieni Hypogeum and the Ġgantija temples on Gozo, the Malta megalithic temples guide covers all the major sites and how they connect.
Is a guided tour worth it?
The site is self-explanatory with the museum displays and the cave labels, so an independent visit is straightforward. The main advantage of a guided tour is that it handles the driving and combines Ghar Dalam, Ħaġar Qim and Mnajdra into a single five-hour circuit from Valletta – practical if you do not have a car or prefer not to navigate the south Malta roads.
Either way, the south Malta circuit – cave, temples, Blue Grotto – is the most complete prehistoric and coastal day you can build on the island.
