You arrive where humidity hangs heavy in the air and the jungle seems to lean toward the water, as if curious about what you’ll do next. A narrow track lets out onto a series of small turquoise pools carved into limestone and sheltered by steep cliffs; platforms and a metal zip frame punctuate the surface, daring you to launch. Around you, the lagoon’s surface reflects palms and a sky that can turn suddenly electric in a Caribbean squall.
