Opelbad

The Opelbad is Wiesbaden's historic open-air pool on the Neroberg hill, reached by the Nerobergbahn funicular, with terraced lawns and a view over the city. Next to the heated pool it has a Finnish sauna for about 40 people at 90°C with automatic infusions. As an outdoor pool it opens only in the summer season, so check the operator's hours before visiting. Adult pool entry costs €12.
