Yet another beach that is a part of the southern seas of Sri Lanka, this beach was named as the best beach in 2004 by the Discovery Channel. Sri Lankans believe that Unawatuna beach was mentioned in Valmiki’s Ramayanaya, which is one of the most famous epics in India. Sea food is the most famous cuisine, and Sri Lankans make a living out of deep sea fishing. The sea temperature is perfect for swimming around the year, and the beach is also ideal for scuba diving and snorkeling. You will be able to see shipwrecks, sea creatures, and a variety of marine wildlife at Unawatuna with deep sea diving. Unawatuna beach lost a lot of its glamour in the tsunami which hit Sri Lanka in 2004, but, much of its luster is still preserved by maritime conservation.
