Baden-Baden is a thermal spa town on the edge of Germany's Black Forest, famous for a bathing culture that reaches back to Roman times and for the glittering 19th-century society that earned it the nickname 'summer capital of Europe.' Mineral-rich hot springs rising at around 69°C from more than 1,200 metres underground are the town's foundation, and in 2021 it was inscribed on the UNESCO World Heritage List as one of the Great Spa Towns of Europe. Its heart is formed by two bathhouses, the historic Friedrichsbad and the modern Caracalla Spa, together with the Kurhaus and its casino and the riverside Lichtentaler Allee. In 2026 it remains a calm wellness destination best approached as a place to slow down and soak rather than sightsee at speed.
Friedrichsbad: a 19th-century neo-Renaissance bathhouse offering the Roman-Irish bathing ritual; on most days it runs as a traditional mixed-gender, clothing-free bath.
Caracalla Spa: a large modern thermal complex with indoor and outdoor pools and saunas, where swimwear is worn, making it easy for families and first-timers.
Kurhaus and Casino Baden-Baden: Germany's best-known casino with nearly 200 years of history and neo-classical halls, the setting that inspired Dostoevsky's novel 'The Gambler.'
Trinkhalle (Pump Room) and Lichtentaler Allee: a frescoed colonnade of regional legends and a 2.3 km riverside park more than 350 years old, both free to enjoy.
Merkur funicular and Roman Bath ruins: Germany's longest and steepest funicular up to Black Forest viewpoints, and 2,000-year-old Roman baths beneath Römerplatz.
Good to know
RulesBy tradition Friedrichsbad is mixed-gender and clothing-free on Monday, Tuesday, Thursday, Friday and Sunday, with swimwear required only on Wednesday and Saturday. If nude bathing is uncomfortable, time your visit accordingly or choose the swimwear-based Caracalla Spa. Entry is only from age 14, and under-18s must be accompanied by an adult.
MannersGerman spas and saunas are quiet spaces for rest. Loud conversation and any photography or filming are frowned upon, and in the sauna you must always sit on your towel. In nude areas, avoid staring at others as basic etiquette.
RulesIn peak season popular baths such as Friedrichsbad can have long waits, so booking ahead is safer. Prices, opening hours and the nude/swimwear day schedule can change with the season and public holidays, so always confirm the latest details on the official websites before you go.
SeasonJuly 2026 is high summer: the weather is mild but the baths and promenades are busy and lodging is pricier. For quieter, cheaper visits, April–June or September–October are better, and Black Forest evenings stay cool even in summer, so pack a light layer.
RulesEntry to Casino Baden-Baden requires photo ID such as a passport and a minimum age of 21, and there is a dress code (a jacket is expected), so sportswear, shorts and sandals may be turned away. If you only want to look around, use the separate guided-viewing hours.
CautionBuy spa tickets only through official websites or box offices, and avoid overpriced resale tickets or taxis that do not run the meter. In crowded spots like the casino, the station and shopping streets, guard valuables against pickpockets by keeping them in front of you.
SafetyBaden-Baden's railway station (Baden-Baden Bahnhof) sits in the Oos district about 7 km from the centre, so you must continue into town by bus (e.g. line 201). If you stay overnight in the Black Forest region you can receive the KONUS guest card for free regional public transport, so ask at check-in.
Practical info
The nearest rail station is Baden-Baden Bahnhof, about 7 km from the centre in the Oos district; from there take a city bus (such as line 201) to the spa quarter around Römerplatz. Friedrichsbad and Caracalla Spa generally open from morning until late evening, but opening times, prices and the nude/swimwear days vary by season and public holiday, so check each bath's official website for the latest information before visiting.
