This clay and stone dam, located in Khao Phang sub-district, is 95 metres high and 700 metres long with a 100-metre-high wall, and features over 100 small islands spread across its vast reservoir. The dam is the south’s second multi-purpose dam and reservoir and doubles as a hydro-electric power station, as well as having agricultural and fishing purposes. Visitors can take a leisurely boat trip around the reservoir to enjoy some great views with the striking limestone peaks in the background and understand why the area is known as “Thailand’s Guilin” One of the most interesting points around the dam and reservoir is ‘Khao Sam Gler’ peak. Affectionately known as the ‘three friends’ by locals, this trio of limestone peaks emerges from the reservoir in a distinctive fashion and is surrounded by incredible views of the surrounding greenery and emerald waters. The Pakarang Cave is located in the 500 Rai inlet and is maintained under the jurisdiction of the Forest Protection Unit, Khao Sok National Park. The name translates as ‘cave of corals’ and is so named due to the stalagmites and stalactites formed from eroded limestone which resemble an underwater coral reef. There have also been numerous fossils unearthed in the area, which have been dated back to a period between 250 and 400 million years ago.
