Kaisertal — The Stairway to Heaven

Voted Austria’s most beautiful place in a national poll in 2016, the Kaisertal is a legendary valley nestled between the Zahmer Kaiser and Wilder Kaiser massifs. For decades, it was the only inhabited valley in Austria with no road access. Even today, only residents are allowed to drive, making it a hiker's paradise. The journey begins with the 'Kaiseraufstieg'—a relentless series of nearly 300 vertical steps that lead over the Sparchner Gorge. Once past the stairs, the valley opens into a pastoral world of historic mountain inns, chapels, and soaring vertical limestone walls.

It is remarkably rare for a major European capital to have a pristine expanse of ancient primeval forest just 20 kilometers from the city center. Tyresta National Park is Stockholm's wilderness backyard. The premier hike is the purple-blazed Tyrestarundan (The Tyresta Circuit), a 14km (8.7-mile) loop that functions as a highlight reel of Swedish nature. The trail takes hikers through dark, moss-draped ancient pine forests (with trees over 400 years old), past three distinct glass-like lakes, and directly through the stark, silver skeletons of the 1999 forest fire zone. It is immaculately maintained, featuring fire pits with supplied wood, making it the significant accessible day hike.
