San Gallán Island, also known as Sangayán Island, is a Peruvian island located in the Pacific Ocean, 5,2 km west off Paracas Peninsula, separated from it by El Boquerón strait.[1] The island lies within Paracas District, Pisco Province, region of Ica; and is also part of Paracas National Reserve.
San Gallán Island has an area of 9,32 km² (4,5 km long, 3,85 km wide) and is located at 13º 50’ S, 76º 27’ W in the Pacific Ocean.[2] At 0,5 km northwest of the island, the Mentiroso Islets can be seen. The main elevation of the island is located at La Viuda Hill (412 m).[3]
The island's arid climate is influenced by the presence of the cold waters of the Humboldt Current. The island has a lighthouse with a light that can be seen from 20 miles.
