The waters that lap the shores of Tuk Tuk are safe for swimming, though they can be dirty; the roped-off section of the lake by Carolina’s, complete with pontoons, canoes and a diving board, is the most popular place. There are also a few activities on offer in Tuk Tuk, including guided treks through the interior of the island and speedboat trips to Tomok, Ambarita and Simanindo. You can also rent bicycles and motorbikes, should you want to visit the more far-flung reaches of the island.
