The main reason for visiting the island for by far the most people is the so called Blue Lagoon Malt: Bejn il-Kmiemen (http://berezko.net/image/...), a stunning lagoon located on the northwest side of the island which has exceedingly clear azure-blue water. Unfortunately in the high season between 10:00 and 16:00 several hundred people swamp it each day, snackbars are set up on the pristine waterfront, deckchairs are rented out and all kinds of different craft go in and out of the lagoon ferrying visitors back and forth. The best time therefore to come is early in the morning as this is also when the water sparkles the most beautifully in the sun.
Less well known is the Crystal Lagoon which has emerald green water almost equally beautiful but unfortunately very little opportunity to swim from the shore as it's surrounded by cliffs. From a boat however it can be a welcome break from the busy Blue Lagoon as it's a lot quieter.
There is also the island of Cominotto Malt: Kemmunett, situated less than a hundred metres away from Comino itself. The island has a tiny beach that opens onto the Blue Lagoon. This beach is popular with tourists wanting to get away from the crowded rockfaces of Comino, but be prepared to either hire a boat to get you out there or, if you can swim, buy a waterproof bag for your beach towels and swim to the island. If the tide is low you can wade across most of the distance.
Comino offers some of the best opportunities for Scuba Diving in the Mediterranean, including the Santa Maria Caves. Water visibility is usually excellent with an abundance of marine life to view, particularly in August / September. There is a dive center (http://www.cominodivecent...) attached to the Comino Hotel, and other operators from Malta and Gozo offer trips to Comino's waters.
