This document summarizes an eco-tourism case study of the Ulagalla Resort in Sri Lanka. The resort was designed based on the components of eco-tourism, which include being located in a natural area and minimizing negative environmental impacts. Specifically, the resort generates 50% of its energy through solar power, uses renewable materials, and has planted over 1,600 trees. It also employs sustainable practices like rainwater harvesting, wastewater treatment, organic gardening, and the use of electric vehicles to reduce pollution. The case study demonstrates how the Ulagalla Resort successfully supports eco-tourism and environmental protection.
