You wouldn’t suspect it, but beneath the sparkling surface of volcano-ringed Lago de Atitlán there lies a secret: Guatemala’s very own Atlantis.

Samabaj is Guatemala’s first underwater archaeological site to be discovered and excavated. Don your scuba gear, slip beneath the waves, and visit this unearthly ruin.

Inspect huge ceremonial stones and ceramic artifacts, while curious fish explore ruined structures.

This is one of the great freshwater dives in the world—and it’s even suitable for beginners. And down here the ruins are changing, Mayan mystery now tingling with marine presence.
