The island has about 13 inhabitants (2022). The Ingøy radio transmitter is located about south of the village of Ingøy. Fruholmen Lighthouse lies just off the northern coast of the island.[2]
From the northwest, the broad Mafjorden cuts into the island of Ingøya and on the east side there is an open bay called Sanden.
The southwestern part of the island is quite mountainous with the highest peak being the 332m (1,089feet) tall Mafjordfjellet. The southern and eastern parts of the island are flat and partially swampy. The northern part is a more mountainous part where the fishing village of Ingøy is located. Ingøy Church is located in Ingøy village. Historically, Mafjorden, Gåsnes, and Ingøy were all large fishing villages. There were two whaling stations located in Mafjorden that operated until the early 20th century.[3]
