Mineral Springs information
Lonely Planet review
At Hierve El Agua, 13km southeast of Mitla, bubbling mineral springs run into bathing pools with a dramatic cliff-top location and expansive panoramas. Hierve El Agua means ‘the Water Boils,’ but the mineral-laden water is actually cold. Water dribbling over the cliff edge for millennia has created mineral formations that look like huge frozen waterfalls. Altogether the pools here make for a unique bathing experience.
