The legend behind the Dronagiri Parvat is quite amusing. According to Ramayana it was during the epic battle, when Lord Laxman, brother of Lord Rama, was fatally injured by Meghnad, the son of King Ravana, the need of the medicinal herbs arouse. To bring it Lord Hanuman, the monkey God, flew to the Himalayas and brought the tip of Dronagiri Mountain to this place. As it was dropped here the beach is called Unawatuna meaning here it fell. This is the mythological reason for the medicinal source of the hill. The bio diversity of the Rumassala Mountain or Dronagiri Parvat is mainly due to the climate and natural abundance of the region. The tourists visit this Rumassala Mountain all round the year and also visit other sightseeing spots like the peace pagoda of Rumassala and the Hanuman Temple on the edge of the place.
