Underground (or underwater) adventures to add to your to-do list.
The captain of the 14-passenger speed boat expertly navigated the choppy Caribbean Sea, avoiding sizable waves and instead riding the calmer currents.
As we approached a trio of dramatic, slate-colored rocks guarded by black-and-white masked boobies and frigates, we quickly strapped on our dive equipment and plunged in the sea.
Before beginning our descent, we swam along part of a 50-foot cave carved into the mammoth rock formations. The ebbing current made us rise and fall as we passed through the cave.
This trip to Honduras piqued my interest in crawling, swimming, and diving through caves all around the world — from those that shelter nesting animals to ones filled with thousand-year-old calcifications. Still others contain luminous pools, or glittering channels of ice. Some can be reached by foot, while others require boat rides, or diving equipment.
“Cave diving is [one] of the few forms of true exploration that remain for everyday people,” Karl Shreeves, a PADI (Professional Association of Diving Instructors) technical development executive told Travel + Leisure. “If you commit yourself to it, eventually you can even explore a virgin cave.”
Because cave diving involves specialized training, there also many other ways to explore both land as well as sea caves. Travelers can spot endangered and rare marine life, like glow worms in Auckland and butterfly bats in Cuba. And if you don't mind getting wet, you can do so in the coastal sea caves of Wales, or while trying paddleboard yoga in a tranquil Park City cave.
From the American southwest to the South Pacific, these extraordinary caves are unlike anywhere else on Earth.
