It is located in Andøy Municipality, Senja Municipality, Harstad Municipality, and Kvæfjord Municipality. The fjord primarily flows between the large islands of Andøya and Senja. Grytøya and the smaller islands Bjarkøya and Krøttøya are located in the fjord. The main crossing is via the Andenes–Gryllefjord Ferry.

The fjord is about {{convert|60|km}} long, has a maximum width of {{convert|30|km}}, and has a maximum depth of {{convert|517|m}} 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.{{cite web|url=http://snl.no/Andfjorden|title=Andfjorden|author=Store norske leksikon|authorlink=Store norske leksikon|language=Norwegian|accessdate=2012-08-05}}

At the tiny Steinavær islands in the Andfjorden, there is a large coral reef.
