You step off the minivan into humid jungle air and the guide hands you a headlamp — sunlight filters through a canopy of ceiba and gumbo-limbo while the trail pulls you toward a dark mouth in limestone. The "secret river" opens as a cool underworld: water that dares you forward, passages carved by millennia and chambers ringed with stalactites that drip an ancient rhythm.
