Isomäki (in Swedish: Storbacken) is one of the districts of Pori.
The area is meant for sports activities and there are no residential buildings.
To the south is the Pori forest, which is thought of as a part of the Isomäki sports centre.
[1] Isomäki is home to an ice hockey arena, the Pori Stadium, an outdoors ice rink.
Next to the ice rink is Karhuhalli, used by footballers and other athletes.
