Little Guilin, Thailand, is the first time to come to Sukhumvitani, the beautiful secret of the mountain. At 6 o'clock in the morning, I set off to Ratchah Reservoir Ratchaprapa Dam and took a boat to the Shilin area. This place is also known as Xiaoguilin, Thailand. The scenery is still very good [happy] The Rachababa Reservoir is located in Kauso National Park. In 1982, the Thai Electric Power Authority (Electricity Generating Authority of Thailand) built this reservoir on the basis of a river flowing through Sukhumvitani, and the artificial lake formed became Cheow Larn lake. The most fascinating thing on the lake is the various stone forests formed by limestone terrain, and the water in the entire reservoir is greenish because of the mineral content. Kauso National Park is one of the largest tropical rainforest areas in Thailand, one of the world's three major karst terrains, not only has a longer history than the Amazon rainforest, strange rocks, magnificent mountains, water green sky blue, intertwined a pair of paradise landscape paintings.
