Black Forest for Couples: Thermal Spas, Trails & KONUS

Rhine valley ICE gateways and the KONUS Guest Card

ICE trains along the Rhine valley stop at Karlsruhe, Baden-Baden, Offenburg and Freiburg, with Basel EuroAirport just south of the region. Scenic mountain railways such as the Schwarzwaldbahn (Offenburg to Konstanz) and Höllentalbahn (Freiburg to Titisee and Schluchsee) climb straight into the uplands.

Around 150 participating municipalities issue the KONUS Guest Card at check-in, giving overnight visitors free second-class travel on regional trains and buses across the entire Black Forest transport zone.

• Main rail gateways: Baden-Baden and Karlsruhe in the north; Offenburg and Freiburg in the south.
• KONUS coverage: valid on regional trains (IRE, RE, RB, S-Bahn) and local buses across nine transport associations, excluding ICE/IC and mountain cableways.
• National park access: buses link Baiersbronn, Freudenstadt and Achern with the Black Forest High Road (B500) and National Park Centre Ruhestein.

Thermal bath towns, high forest valleys or southern lakes

Northern Black Forest bases such as Baiersbronn and Bad Wildbad combine fine dining, quiet cirque lakes (Karseen) and direct access to Black Forest National Park trails around Ruhestein and Mummelsee.

In the south, Hinterzarten, Schluchsee and St. Blasien offer high-plateau air above 800 metres, Feldberg panoramas and sunlit wine villages in the Markgräflerland foothills near Freiburg.

• Baiersbronn and National Park rim: culinary hideaways, pine-scented trails and quiet side valleys.
• Hinterzarten and Schluchsee: direct Höllentalbahn rail stops, glacial lakes and Ravennaschlucht gorge.
• Badenweiler and Kaiserstuhl foothills: Roman bath heritage, mild microclimate and Burgundy-style wine estates.

• Hotels with sauna and hot tub
• Hotels with private sauna
• Cabins with hot tub

Cross-Rhine pairings with Alsace or Lake Constance

Because Strasbourg and Colmar sit just across the Rhine, a five-day itinerary easily joins two nights in Alsace with three spa nights in Baiersbronn or Hinterzarten.

Alternatively, ride the Schwarzwaldbahn all the way from Offenburg through Triberg's wooded valleys down to Lake Constance for a forest-and-water contrast.

• Cross-border gourmet trip: Strasbourg or Colmar (2 nights) plus Baiersbronn or Hinterzarten (3 nights).
• Scenic rail traverse: Freiburg to Titisee/Schluchsee on the Höllentalbahn, continuing toward Lake Constance.
• Northern heritage pair: Heidelberg (2 nights) plus northern Black Forest spa hotel (2-3 nights).

Timing forest walks and thermal spa days

May through October brings long daylight on ridge trails such as the Westweg and Schluchtensteig, with October adding golden beech foliage and new-vintage wine tastings along the Badische Weinstraße.

Winter turns misty forest valleys into cosy sauna territory; check whether your chosen municipality participates in KONUS before booking if you plan to travel without a car.

• Confirm KONUS participation directly with your hotel, as big fringe cities like Freiburg and Baden-Baden have separate municipal rules.
• Book gourmet tables in Baiersbronn well ahead for Friday and Saturday nights.
• Choose Hinterzarten or Schluchsee over busy daytime spots at Titisee pier for quieter mornings.
