Mount Pico
Região Autónoma dos Açores
Mount Pico, located on Pico Island in the Azores archipelago, is a dormant stratovolcano and the highest peak in Portugal at 2,351 meters (7,713 feet). It forms part of the Madalena Volcanic Complex and features a large summit crater called Pico Alto, approximately 500 meters in diameter and 30 meters deep. Within this crater rises Piquinho (also called Pico Pequeno), a smaller volcanic cone that forms the true summit. The volcano last erupted in 1720 from flank vents, with historical lava flows reaching the sea. The mountain is a designated nature reserve since 1972, encompassing about 1,500 hectares from 1,200 meters altitude to the summit. Mount Pico's geology is characterized by two main fault systems and a variety of volcanic formations including cinder cones and lava flows. Its summit hosts the PICO-NARE observatory, an international scientific station studying atmospheric aerosols. The mountain's diverse altitude zones support rich endemic flora, including laurel forests, and unique fauna. It is a popular but challenging hiking destination, requiring proper preparation and guidance due to variable weather and terrain. The surrounding landscape includes notable features such as highland lagoons and the UNESCO-listed Vineyard Culture of Pico Island at its base.
ヒント: The best time to climb Mount Pico is during the summer months when weather conditions are more stable. Hikers should be physically fit, equipped for sudden weather changes, and ideally accompanied by a local guide familiar with the trails. It is recommended to reserve guided tours in advance, especially during peak season. Visitors can benefit from discounts by booking group tours or through local tourism packages. Always check weather forecasts and volcanic activity updates before planning your ascent.

歴史
Mount Pico formed approximately 750,000 years ago and is the youngest major volcano in the Azores.
Its last eruptions occurred on its southeast flank in 1562–1564, 1718, and 1720, producing lava flows that reached the sea.
The mountain was designated a nature reserve in 1972 and later became part of the Natural Park of Mount Pico, reflecting its environmental and geological importance.
The establishment of the PICO-NARE observatory in 1998 marked a significant milestone in scientific research on atmospheric conditions over the North Atlantic.
場所ガイド
Pico Alto CraterHolocene (less than 6000 years ago)
A large, roughly circular summit crater about 500 meters in diameter and 30 meters deep, forming the top of Mount Pico. It is the main volcanic pit crater of the stratovolcano.
Piquinho (Pico Pequeno)Geologically recent (Holocene)
A small volcanic cone rising approximately 70 meters within the Pico Alto crater, representing the true summit of Mount Pico. It is the highest point in Portugal.
East Fissural ZoneHolocene
An area on Pico Island comprising alignments of cinder cones and lava flows formed by Hawaiian/Strombolian eruptions. This zone includes several volcanic cones and lava deltas called fajãs.
PICO-NARE ObservatoryEstablished 1998
An atmospheric research station located on the summit caldera at 2,225 meters altitude, operated by the University of the Azores and international partners. It studies aerosol particles and air pollution impacts over the North Atlantic.
Lagoa do Capitão
A highland lagoon situated on the interior plateau of Mount Pico at approximately 1,500 meters elevation. It is part of the mountain’s diverse altitudinal ecosystems.
