Thermal culture in Switzerland
Germanic sauna culture (Textilfrei or FKK sauna) mandates nudity in sauna areas. Entering a sauna in swimwear is considered unhygienic and is often prohibited. This creates a uniquely naturist-friendly environment where nudity is the norm, not the exception. The sauna landscape (Saunalandschaft) in German, Austrian, Swiss, and Slovene spas is typically extensive, beautifully designed, and entirely textile-free.
Practical advice
- Always shower thoroughly before entering any thermal pool, spring, or sauna — this is a universal rule
- Bring a small quick-dry towel specifically for sitting on sauna benches
- Ask about photography policies — most thermal venues strictly prohibit all photography
- Check if the venue is gender-segregated, mixed, or offers both options
- Hydrate before and after thermal bathing — heat and minerals dehydrate rapidly
- Remove all jewellery before entering mineral-rich thermal water — it can tarnish or be damaged
- Limit your first session to 10–15 minutes and build up tolerance gradually
