Rio Secreto, or the “Secret River,” is a series of caves carved out by the flow of an ancient underground river in Mexico.

A signature landmark of Los Cabos, El Arco de Cabo San Lucas—known locally as simply “El Arco” or “the Arch”—is a limestone arch carved by time, tide, and wind.

From a distance, the rock formation looks like a dragon; up close, the arch frames sky, sea, and sand for prime photos.
