It is the highest mountain in Portugal, at 2,351 meters, culminating in the crater of Pico Grande, where Pico Pequeno rises, whose base emanates fumaroles. It is classified as a Nature Reserve, and in 2010, its volcanic landscape was named one of the Seven Natural Wonders of Portugal. It is possible to climb it during the summer months with a guide.

A volcanic formation, approximately 5,150 meters long, it is the largest known lava tube in Portugal. It was formed by lava ejected from a volcanic eruption in Cabeço Bravo, and today, curious geological structures such as stalactites, lava stalagmites, and lava balls can be seen.

The landscape of Pico Island's vineyard culture comprises the Lajido da Criação Velha and Lajido de Santa Luzia, occupying a total of 154 hectares. These sites are excellent representations of traditional architecture, landscape design, and natural elements, located on extensive lava fields. They are characterized by extreme richness and geological and scenic beauty. The diversity of fauna and flora present there is associated with an abundance of endemic, rare, and protected species and communities. Since 2004, the landscape of Pico Island's vineyard culture has been classified by UNESCO as a World Heritage Site.
