Adventure-seekers will find no more rewarding excursion than the Snowman Trek, an intensive 24-day hike that crosses 11 high-altitude peaks, remote villages and some of the world's greatest views. It is considered to be one of the most difficult treks on the planet and should only be attempted by experienced trekkers.

The Mooserboden and Wasserfallboden high mountain reservoirs in Kaprun, which lie between the commanding cliffs of the Upper Tauern at a height of 2,000 metres, can be reached with Europe’s largest open slant lift. During a guided tour of the dam wall on the 107-metre-high and almost 500-metre-long “Mooser-Sperre” visitors can discover how clean electricity can be generated from 160 million cubic metres of water. The "Electricity Adventure World“provides insights into the fascinating world of eternal ice and explains the interplay between the glacier, power plant construction and electricity generation.

The Kunstmuseum Stuttgart is hard to miss—by day, it’s a sleek glass cube reflecting the city; by night, its illuminated limestone core glows from within. The museum holds around 5,000 square metres of exhibition space, much of it tucked beneath the square in repurposed tunnels. It’s home to the world’s largest collection of works by Otto Dix, including his famous triptych Großstadt. The collection also includes pieces by Adolf Hölzel, Willi Baumeister, and other key figures in modern and contemporary German art.

Schloss Solitude sits on a quiet ridge just outside Stuttgart, built in the 1760s as Duke Carl Eugen’s rather extravagant idea of a hunting lodge. It’s Rococo inside and out—decorative, symmetrical, and full of detail. You can join a guided tour or just come for the surroundings: forest paths, a long avenue that leads back to the city, and a view that opens wide on a clear day.
