Ratnapura, located on the Kalu Ganga, is a major city in SriLanka and is the capital city of the Sabaragamuwa Province. Its name has a Sanskrit meaning translating to ‘City of Gems’ and as such it is the traditional center for the Sri Lankan gem trade. B We found Ratnapura to be green and lush and while we knew that the city is famous for its gems, we were surprised to find how much more Ratnapura had to offer!Udawalawe National Park, the sixth largest animal sanctuary of SriLanka is located 180 km from Colombo in south-central sector of the island.
