Hierve el Agua Petrified Waterfalls
Set against a dramatic mountainous backdrop, Hierve el Agua is one of only two petrified waterfall sites in the entire world. Over thousands of years, mineral-rich spring water has trickled over the cliff edge, depositing calcium carbonate to create massive, white rock formations that look exactly like frozen cascades. Visitors can hike down to the base for a staggering view looking up at the formations, or relax in the natural infinity pools situated right at the cliff's edge. Despite the name meaning 'the water boils', the mineral springs are comfortably cool. It is a phenomenal geological wonder.
