The low-angle, grass-covered eastern slopes of Cerro Tilarán (also known as Cerro Tovar) are seen from the SW part of the town of Tilirán. The small 634-m-high andesitic shield volcano lies at the NW end of the Tilarán Range west of Lake Arenal. The Tilarán shield is overlain only by tephra deposits from Arenal (maximum age about 7000 years), but has an Argon-Argon date of 1 million years.
