Cerro Marahuaca, Alto Orinoco-Casiquiare Biosphere Reserve

Cerro Marahuaca, also spelled Marahuaka, is a tepui in Amazonas state, Venezuela. It has an elevation of 2,832 metres above sea level and is the second-highest mountain of the entire Guayana Shield. Cerro Marahuaca shares a common base with the much larger Cerro Duida and together they form the Duida–Marahuaca Massif. Both tepuis are located entirely within the bounds of Duida–Marahuaca National Park. ()
