Moss-dark limestone rises from humid air as the trail slips into shade—an immediate shift from seaside bustle to a quiet island interior. The path threads through mixed evergreen and secondary forest, then climbs toward a broad cave mouth where light and cool stone meet. Inside, stalactites dangle like slow-moving chandeliers and a hush holds the history carved into the rock.
