Naturbad Riehen — Sauna

The Riehen Natural Bathing Area is situated on the border with Weil am Rhein and Lörrach, nestled between the vine-covered Thüllinger Hill and open countryside. Herzog & de Meuron designed it as a natural-looking swimming lake surrounded by plants, with an operations building made entirely of timber; in 2015, it received the GOLD Award from the IOC and IAKS, as well as a commendation from the Prix Lignum. When the swimming area is closed in winter, a small sauna village is heated up here.

What makes it special is the cooling-off phase: after a sauna session, visitors head to a separate section of the non-swimmers’ pool filled with cold natural water. Afterwards, they warm up by the wood-burning stove in the relaxation yurt or relax on the outdoor loungers by the water’s edge. The team performs the ‘Aufguss’ rituals using 100 per cent natural essential oils; the sauna specialists have undergone further training through the Swiss Sauna Association.

No entry is permitted whilst an infusion is taking place — the waiting time of up to 15 minutes can be spent in the bistro enjoying a cup of tea. On Sundays and Mondays, the entire facility can be hired exclusively for groups of up to 12 people, with infusions, catering or massages available on request.
