Kellon Kraaseli is located off shore from the village of the Kello [fi] district in Oulu.

The name is derived from the Swedish word gråsäl, meaning "gray seals".

Kellon Kraaseli is a low island, with its highest point only a few meters above sea level.

Kellon Kraaseli was used for common pasturage for cows and sheep until the start of the 1980s.

This stretch of water is fairly sheltered, and is used as a common anchorage for fishing boats during stormy weather.
