This crescent-shaped beach is perhaps one of the most visually arresting beaches in Sri Lanka. Ideally situated on the southern coast, near the southern capital of Galle, Unawatuna's natural beauty and the shape of the bay are what make this popular beach paradise well worth the trip, even when it's crowded. Apart from snorkelling and scuba diving, some of the top things to do in Unawatuna include jet-skiing as the shallow waters make for an easy riding experience. Don't forget to hike up Rumassala Hill during your stay in Unawatuna as the mountain offers spectacular views of the beach while also serving as a location where medicinal plants are found.
