The road to Kehlsteinhaus, a teahouse for Adolf Hitler’s 50th birthday

# Eagle's Nest Road: A Mountain Marvel in the Bavarian Alps

Nestled high in Bavaria's Berchtesgaden Alps sits the Kehlsteinhaus—or Eagle's Nest, as it's commonly known. This historic chalet perches at a stunning 1,685m (5,528ft) above sea level on the Obersalzberg Mountain in southeastern Germany, and getting there is half the adventure.

Built in 1938 as a 50th birthday gift for Adolf Hitler, the building has since been transformed into a restaurant and tourist hotspot with absolutely jaw-dropping panoramic views. These days, visitors flock here during summer months (typically mid-May through October) to soak in the scenery and the historical significance of this alpine retreat.

The real star of the show, though? The Kehlsteinstrasse road itself. This engineering masterpiece was blasted straight out of solid rock in just 13 months—seriously, only 13 months to carve 6.5km (4.03 miles) of paved perfection through the mountainside. The road climbs an insane 736m in elevation with an average gradient of 11.32%, peaking at a white-knuckle 24% on some sections. You'll navigate through 5 tunnels and 5 hairpin turns as you ascend the steep northwest face of Kehlstein mountain.

In 1952, the road closed to regular traffic and was replaced by a special mountain bus service—a decision that's proven wise given the extreme conditions. The final ascent to the chalet actually requires taking an elevator blasted through the rock. Before each season opens, crews meticulously clean the rock walls to prevent dangerous rockfall.

It's one of Germany's highest roads and a genuine architectural wonder.
