Neptunbad — historic & Asian saunas
Cologne, North Rhine-Westphalia
A restored historic bathhouse in Ehrenfeld with an Asian-inspired sauna garden, onsen pools and sun terraces. The old hall and modern garden give this neighbourhood spa two quite different settings for a sauna afternoon.

When to go
Year-round operation; consult the operator’s current opening times and maintenance calendar.
Directions & Parking
Getting there
Navigate to Neptunplatz 1, 50823 Köln. Use the public spa/sauna reception rather than any hotel-only entrance. The map point identifies the venue or its street address; the nude section is inside the admission-controlled facility.
Parking
Use the venue’s arrival address above and follow its visitor-parking signs. Check the posted tariff and any ticket-validation procedure on arrival; parking is separate from sauna admission. No reserved parking space is promised.
Finding the naturist area
From reception, ask for admission to the spa reception and sauna changing area. Change in the designated lockers, take a large towel or sheet, and follow the sauna signs to the internal clothing boundary. Remove swimwear where indicated before entering the nude section.
