Kaengkrachan Dam, built across the Petchaburi river, generates a vast and picturesque reservoir and creates a huge lake covering 45 square meters. Located about 60 kilometers from the resort, Kaeng Krachan is presently the largest national park in Thailand covering an area of approximately 1.8 million Rais. Here one can enjoy taking both trips around the reservoir, fishing or trekking through the park.
