This 11-tier scenic waterfall, some 60 kilometers west of Hua Hin, is located within a yearlong verdant forest where various kinds of birds and butterflies are found, especially in the morning.
Pala U Waterfall is in the southern end of the massive Kaeng Krachan National Park – the largest National Park in Thailand. Established in 1981, Kaeng Krachan covers 2,915 square kilometres and straddles two Provinces: Petchaburi and Prachuap Khiri Khan. Fortunately for tourists and residents alike, the falls are located just 64 kilometres west of Hua Hin City. Pala U Waterfall is actually a series of waterfalls, or steps. Comprised of 15 levels, the trek becomes more arduous the higher one climbs. The first 3 stages are pretty manageable for most people, but beyond that the trail becomes much more challenging. Between the falls are cool pools of water where soro brook carp (a fresh water fish) flourish. Feel free to take a dip with them – they might brush against your body due to their massive numbers, but they are harmless.
It is illegal to fish in the park, so the numbers continue to grow. The falls vary in their water flow depending on the time of year. In theory, the rainy season (July to October) is the best time to visit. The water flow is higher, but the trails become slicker and the overall hiking is more challenging. The best time to visit is from November to February. During these months the water level, and therefore the falls, remain active yet the outside temperature is much cooler.
