La India Dormida is a portion of the western rim of El Valle de Antón caldera. A hiking trail leads to the saddle (left) at the base (left) and then to its summit, which rises 300 m above the caldera floor. The caldera wall exposes Tertiary Iguana pyroclastic flow deposits that are overlain by the Tertiary Piedra lava flow.
