There are three modern swimming pools within easy reach by car or bus from Vollen.  These are Risenga swimming-pool at Asker town, Holmen swimming-pool on the route to Oslo, and Røyken swimming-pool which is a 20 minute drive and situated close to Kjekstad Golf Club.
It should be mentioned that the Holmen Swimming Pool building received first prize for architecture in 2018. As it is hoped that many people will visit the pool by bicycle or public transport, there is limited parking for private vehicles.  However free parking is offered at Holmen Shopping Centre nearby.  There are good parking facilities at both Risenga and Røyken pools.
Maps to each of the three swimming pools are below.
