Ratchaprapha Dam is located in Khaopang sub-district of Baantakhuun, Surat Thani province in Southern Thailand. Getting to the dam is no big deal and can be done in more than one way. If you are a plane traveler then the nearest airports for you are Surat Thani Airport, Krabi Airport, and Phuket Airport, then take a public transport to Khao Sok National Park‘s entrance.
Train is also an option since that Surat Thani has a train station but you will have to follow it by a bus or similar transport to Khao Sok (trains are subject to delays though). Taking the bus is a very simple option especially if you are already in Surat Thani, there are multiple bus rides to Khao Sok from Surat Thani, you can also take a bus from Phuket, Takua Pa, Bangkok and Khao Lak. Minibusses and vans are a popular option, these can be taken with a combination of bus and boat transports from Koh Phi Phi, Koh Phangan, and Koh Samui as well as the bus only from Surat Thani and Bangkok. By boat, however, is the most suitable option for travelers on a budget and for island to island traveling.
Ratchaprapha or Cheow Lan Dam is a multipurpose dam; it is built for irrigation, electricity generation, flood control, and fishing. King Bhumibol Adulyadej gave it the sweet name “Rajjaprabha” meaning the light of the kingdom. The dam is 165 meters long and 95 meters high with clay core. Cheow Lan Lake has many visitors that come from all around the world to enjoy its beautiful scenery and serene water.
