Namtok Sai Yok Noi, also known as Namtok Khao Pang, is a beautiful waterfall located in Thailand's Nam Tok district. This spot is popular amongst local Thais, who come to swim in the refreshing waters and enjoy picnicking in the shade of the trees. Along with this scenic getaway, there is also an authentic WWII-era Japanese steam train parked onsite, making it a great spot to explore and learn about history. The area is part of Sai Yok National Park, meaning no entrance fees are required. Sightseers can also hike up to Tham Sai Yok for cool photo opportunities or to explore a holy snake-shaped rock! With picturesque waterfalls, views of a historic steamtrain and plenty of picnic spots and swimming areas, Namtok Sai Yok Noi is the perfect spot for a weekend escape.
