Swimming pools overview

Sunbathing

From now on: Smoking only permitted in designated areas (state non-smoker protection law)
The non-swimmers' pool is currently out of use.

The Sonnenbad, built in 1915, is a unique outdoor pool that is known for its long opening hours. The cult pool, located on Karlsruhe's Rhine harbour, was one of the first open-air pools in Germany to start the swimming season and is open longer than any other open-air pool in Karlsruhe. Due to its location, the pool is also known by many as the Rheinhafenbad. From around mid-March to around the end of October, bathers can enjoy the open-air pool air. The opening of the season at the Sonnenbad is well known throughout Germany and is featured in the public media, as the annual Anbaden is celebrated in cooperation with the Freundeskreis Sonnenbad. Even visitors from outside Germany don't miss the early opening of the pool.

In addition to the longest outdoor pool season, the Sonnenbad is the only outdoor pool in Karlsruhe with a small sauna area. A total of 2 sweat rooms (60 degrees and 85 degrees) invite you to take a sauna after swimming in the heated 50-metre swimming pool. A total of 6 lanes are available. The large massage mushroom provides relaxation after swimming laps. A non-swimmers' pool with a slide and a paddling pool are available for younger bathers in the main season. The large sunbathing lawn with playground at the back invites you to sunbathe.

It doesn't matter whether you are a hobby or sports swimmer (no pool lifts).

Thanks to the Freundeskreis Sonnenbad e. V., the children's playground at the back of the sunbathing lawn has been making children's hearts beat faster since summer 2015. While mum and dad soak up the sun on the lawn, the little ones have a great time playing.
