At its foot lies the small settlement of
La Esmeralda, from which the mountain can be climbed.

Cerro Duida shares a common base with the much smaller (but taller)
Cerro Marahuaca, located off its northeastern flank, and together they form the Duida–Marahuaca Massif.
Both tepuis are entirely within the bounds of
Duida-Marahuaca National Park. Sandwiched between them, a massive ridge known as
Cerro Petaca rises to at least . The much lower
Cerro Huachamacari, derived from a separate base, lies to the northwest of this complex.
Tyler-Duida expedition
George Henry Hamilton Tate led a major expedition of the
American Museum of Natural History to Cerro Duida in 1928–1929.
Named the
Tyler-Duida Expedition, it was the first to reach the mountain's summit plateau and the first to climb a tepui of the Venezuelan
Amazon
Amazon most often refers to:
* Amazon River, in South America
* Amazon rainforest, a rainforest covering most of the Amazon basin
* Amazon (company), an American multinational technology company

was first collected during the expedition and is still not known from anywhere else, although it was formally
described only 40 years later. Although primarily a zoological expedition, much plant material was collected.

Henry Gleason, who
formally described many of the mountain's plant species in a series of papers published in 1931.

Botanical results of the Tyler-Duida Expedition. ''Bulletin of the Torrey Botanical Club'' 58(8): 465–506. ] This was followed by a number of important botanical explorations of Cerro Duida, first by
Julian A. Steyermark in
