Raatin uimahalli is the City of Oulu's swimming hall on Raatinsaari island, about a kilometre from the centre, part of the Raatti sports centre. It has two 25-metre pools, a children's pool, a teaching pool and a small cold plunge pool, plus separate saunas in the men's and women's changing areas. By the city's rules, the showers and saunas are used without a swimsuit. A single adult swim costs EUR 6. The cold pool closes daily from 11:30 to 13:30 for maintenance.
