Rumassala

Chhaya Methani
It is said that Unawatuna closely resembles the paradise beaches described in Valmiki's Ramayana. According to the epic, when Hanuman was asked to get specific herbs needed to treat Laxman, he carried the whole mountain since he was unable to differentiate between the many herbs growing atop. On his flight back, a small part of the mountain 'dropped' down to earth, and is believed to now lie as a small hill close to the Unawatuna beach, called the Rummasala hill. The beach thus got it's name, Una-watuna, literally meaning "fell down". Rummasala hill now also acts as an excellent vantage point providing excellent views of the beach. It also acts as a crowd filter, since only the few who really crave for a secluded experience, venture out for the hike down to the beach. And aren't we glad for this natural filter! ;)

You gotta hike up a small distance on Rummasala hill and then behold! You are greeted by a beautiful beach line richly lined with coconut trees, dotted with lazy clouds admiring the whole scene from above.
