Hikkaduwa’s marine park stretches along the northern end of the beach and is a fun and easy way to get a glimpse of some of Sri Lanka's undersea life. Snorkelling gear can be rented from places around the park ticket office for around Rs 300 to Rs 500 a day. Glass-bottomed boat rides (not an ideal way to see the reef) are available for Rs 1750 (plus 10% tax) per half-hour. The boats can be hired from beside the National Park Ticket Office.
