Sai Rung Waterfall: Ramkhamhaeng National Park's Hidden Rainbow Gem

Highlights

Sai Rung Waterfall, aptly named 'Rainbow Waterfall' in Thai, offers its most spectacular views when sunlight penetrates the mist created by its descent from a high cliff. Between 11:00 AM and 4:00 PM, when the sun's angle is just right, vibrant rainbows magically appear, a truly captivating natural event. The waterfall originates from Khao Chedi, forming the Phai Na Canal which flows southwest. The area is also home to a Ramkhamhaeng National Park (Khao Luang) protection unit.

The waterfall comprises four distinct tiers, each offering picturesque views and opportunities for a refreshing dip. To reach these tiers, visitors embark on a scenic trek along the stream from the park's protection unit. The distances to each tier are approximately 800 meters, 900 meters, 1,160 meters, and 1,200 meters respectively.
