While thousands of tourists flock to the Blue Lagoon, just a few hundred metres away hides its quieter sister — Crystal Lagoon. Enclosed by vertical cliffs on three sides, accessible only from the water (by kayak, boat, or swimming), this lagoon offers something the Blue Lagoon can no longer provide: peace.
Underwater visibility reaches 30 metres — among the best conditions in the entire Mediterranean. The seabed is covered in white sand and rocky reefs, and in the crevices live octopuses, moray eels, and hundreds of colourful fish. Divers call this place "underwater cinema" — there's that much to see.
Crystal Lagoon formed through thousands of years of marine erosion. Waves carved through coralline limestone — the same rock that all of Malta is built from — until a closed bay with a narrow entrance from the sea emerged. During storm season (October-March), waves force their way into the lagoon with tremendous power, continuing to shape its form.
Best time: early afternoon, when the sun is high and illuminates the lagoon floor. Bring a mask and snorkel — you won't regret it.

A dramatic sea cave with a partially collapsed ceiling that floods the interior with shafts of natural light — hence the Maltese name L-Għar ta' Bla Saqaf (the cave without a roof). Accessible only by boat or kayak from Comino's southern coastline. Nicknamed 'Popeye Cave' by tourists, though the 1980 Robin Williams film was shot in Anchor Bay, Mellieħa — not here.
One-room schoolhouse built in 1948. Served the small permanent community of the island. Abandoned when the last residents left.
