Pigeon Island near Trincomalee is the finest snorkelling site on the island: blacktip reef sharks, hawksbill turtles, and vibrant coral gardens in crystal-clear east coast water a short boat ride from shore. Hikkaduwa’s reef on the southwest coast and the waters around Mirissa offer different marine character and different seasonal windows. Ceylon Travel Escapes arranges all marine experiences with operators whose approach prioritises the health of the environment they work in.
