Our goal for the day had been Sombrero de Chasna but since we reached it s easily we ventured out on the caldera rim, eventually climbing Lomo de las Mesas on its whole length. Instead of descending to Degollada de Ucanca, however, we returned and climbed the summit for a second time.
Climbed the Sombrero following a guidebook tour but were disappointed by the views. Also the promised difficult ascent turned out to be little more than a scramble through a short chimney. Made good for the disappointment by climbing Lomo de las Mesas afterwards.
