Our world is magnificent with beautiful natural wonders that attract several visitors right through the year. However, there are some wonders that can scare the living daylights out of you, or have you toying with the urge to flirt with death and disaster. While the common man might just say no to visiting these places, destiny defying adventure seekers know them only too well.

1. Trolltunga, Norway

Literally translated as Troll's Tongue, Trolltunga is one of the most spectacular scenic cliffs in Norway. It is 1100 meters above sea level, hovering 700 metres above Lake Ringedalsvatnet. The view is breathtaking. The hike goes through high mountains, and takes 8-10 hours in total (to Trolltunga and back), and the ascent is about 900 meters. The hike is usually possible to do from mid June, depending on when the snow melts in the mountains. Do carry an extra pair of pants if you plan on peeking over the edge.

3. Huayna Picchu

The ancient city of Machu Picchu is best viewed atop the summit of this mountain. However, getting there is the hard part. Inhospitable terrain, narrow and steep stairs, and high altitudes can be pretty unnerving.

5. Mont Blanc Box, France

We're not talking about the luxury brand, but the glass box that stands 12,604 feet over the rocks to give you a 360 degree view from Europe's tallest peak. Engineers have assured visitors about its structural durability and the technology that prevents this box from toppling off the edge. But is that enough?
