Hierve el Agua

Hierve el Agua is renowned for its striking, calcified rock cliffs that resemble massive frozen waterfalls, formed over thousands of years by mineral-rich, carbonated spring waters. Perched atop high cliffs in Oaxaca, the site features natural cliffside mineral pools that offer sweeping, expansive views of the surrounding mountain landscape.

Commenters consistently praise the site as a bucket-list destination, highlighting that the steep hike down around the formations is exceptionally rewarding. However, some travelers voiced environmental concerns regarding overtourism and potential contamination of the natural pools.
