Kalpeni has three uninhabited islands which are unbelievably beautiful. Koomel, the gently curving bay where the tourist facilities are located, directly overlooks Pitti and Thilakkam, two of the islands. Here you can swim, reef walk, snorkel or use water sports equipment like kayaks, and sail boats. Now the tourist facilities have been broadened and tourists can stay on the island in privately managed huts. This lagoon is specially rich in coral life.
