The Stairway to Heaven (Sky Ladder) – Austrian Alps
What is it? A vertically exposed via ferrata route featuring a nerve-wracking steel cable ladder that looks like it’s going into the clouds.
Where? The Dachstein Mountains of Austria.
What it involves: climbers ascend over 40 meters on near-vertical steel ladder with nothing but air beneath them – it’s part of a longer via ferrata route with amazing views.
Highlights: the crazy feeling of climbing a ladder into the sky, with breathtaking 360* views of the Austrian Alps.
How to do it: the climb is usually done between June - September. You'll need via ferrata equipment including a harness, helmet, and special pass. Always go with an experienced guide unless you have significant via ferrata experience (you’ll know if you qualify as that!)

Highlights: only 15 people have completed all 5 loops – and it’s been going since 1986. There were no finishers this year.
How to do it: you’ll need to send an essay and answer a series of bizarre questions to explain why should be allowed to take part. The entry fee is $1.60.
Mount Hua Plank Walk – China
What is it? An infamous hiking trail made of wooden planks attached to the side of a sacred mountain 2,000 meters above sea level.
Where? Mount Hua (Huashan), near Huayin in Shaanxi province, China.

Mongol 100 – Mongolia
What is it? A 100-mile ultra-endurance event across a frozen Mongolian lake in winter.
