At the Arendal marina you will find Norway's first floating outdoor swimming pool. The temperature should hold 25-26 degrees Celcius or 77-79 degrees Fahrenheit.
So how about a morning swim in agreeable temperatures with the old town Tyholmen as a beautiful backdrop.
The pool measures 25 X 10 X 1,2 meters. Therefore it will not be possible/allowed to dive in the pool.
Children under the age of 10 years must be accompagnied by an adult swimmer.
Locker room and shower available.
