Sai Ku Waterfall, Prachuap Khiri Khan

Sai Ku Waterfall in Prachuap Khiri Khan is a stunning natural attraction with a total of 9 tiers. The 2nd and 3rd tiers are relatively small waterfalls, while the 4th tier is the origin of the name 'Sai Ku Waterfall.' The 5th tier is particularly popular among tourists due to its large and beautiful rock cliff. The 6th tier requires climbing, but we couldn't reach it. Location: Bang Saphan District, Prachuap Khiri Khan Province.
