Mirador Antaymarca is the place to make sense of Andagua. From here the valley opens out: small volcanic cones rise from the floor, dark lava fields cut across farmland, and the high walls of the Andes make the whole scene feel boxed in.
Go early or late if you can, when the low light gives shape to the black rock. The viewpoint also pairs naturally with the nearby Antaymarca ruins.
