Watch the sunlight bouncing off the water as it tumbles over Hui Yai Waterfall. Keep an eye out for any rainbows in the mist.
When you've spent a bit of time at this Wang Nam Khiao cascade of water, why not make your way to Montana Farm, Wat Bu Pai, and Pha Kep Ta Wan? They're close to Hui Yai Waterfall and also a favorite with tourists.
