Kanchanaburi's two best-known waterfalls, two very different visits
Erawan Falls and Sai Yok Noi are Kanchanaburi's two best-known waterfalls, but they offer very different visits. Erawan is a seven-tier hike through turquoise pools. Sai Yok Noi is a free roadside waterfall at the end of the Death Railway line. Here's a real, 15 point comparison.
Choose Erawan Falls if you want the famous turquoise pools, a proper hike and the best swimming. Choose Sai Yok Noi if you're riding the Death Railway, visiting Hellfire Pass or want a quick, free stop in the rainy season.
