Buatong Waterfall-Chet Si Fountain National Park

This guide to Buatong Waterfall outside Chiang Mai opens with a Lanna legend of two fugitive princesses, Bua Tong and Bua Kaew, hiding from invaders in a cave with no water. It follows how their prayer to the goddess Mae Thorani is said to have unlocked the mineral spring behind these odd, grippy limestone tiers. You'll also hear how a site locals once kept sacred and remote became a crowded hillside only in the last couple of decades.
