Trindade is a mountainous, desiccated volcanic island with numerous phonolitic lava domes and steep-sided volcanic plugs. The highest summit is Pico Desejado, near the center, high. Nearby to the northwest are Pico da Trindade () and Pico Bonifácio (). Pico Monumento, a remarkable peak in the form of a slightly inclined cylinder, rises from the west coast to . The youngest volcanism, at Vulcão do Paredão () on the southeast tip of the island, constructed a pyroclastic cone with lava flows that are no older than the Holocene (Almeida, 1961). Remnants of the crater of the cinder cone are still preserved. Lava flows traveled from the cone to the north, where they formed an irregular shoreline and offshore islands. Smaller volcanic centers of the latest volcanic stage are found in the Morro Vermelho () area in the south-central part of the island.
