The fjord is about 60 kilometres (37 mi) long, has a maximum width of 30 kilometres (19 mi), and has a maximum depth of 517 metres (1,696 ft) which makes it a rich feeding ground for Sperm whales and Killer whales. Whale safaris are run from Andenes and from Krøttøya. Several other fjords branch off the Andfjorden including the Kvæfjorden, Godfjorden, and the Vågsfjorden.[2]
At the tiny Steinavær islands in the Andfjorden, there is a large coral reef.
