Earlier this month, the Chinese province of Hunan celebrated the opening of a new bridge with a difference - the walkway was built from glass.

This means that you can now cross the dodgy rope bridge whilst staring down at the impending drop, because what budding traveller hasn't complained that the bridges in their way were 'a bit too safe' every now and then.

To celebrate the opening, we've put together a collection of glass-floors from around the globe that have no doubt made some knees go weak and made for some amazing pictures in their time.

Have a read ahead and see which ones you would take on...

glass bridge

The most recent instalment on our list, this 300m glass-bottomed bridge stretches between two rocky peaks above a valley in Pingjang, in the Hunan province of Southern China.

The bridge is 180m above ground, and just in case its users weren’t already panicking enough about the prospect of crossing it, it also sways in the wind.

Mixing that dodgy Amazonian rope-bridge feel with an ambience of ‘holy shit, look how far I’m going to fall’, there’s pretty much no way to feel safe while you’re crossing this bridge.

Luckily enough, trained staff are on site to help nervous travellers across. How reassuring.

GlacierSkywalk2

This particular attraction sees tourists walk out on a glass platform 280 metres above the Sunwapta Valley in Jasper National Park.

The Canadian structure stretches a total of 30m beyond the cliff edge to give a scarily unique viewing point of the stunning surroundings, and it cost over £12 million to develop before opening earlier this year. 

If you’ve not seen pictures of the National Park before, clear your schedule and get Google Images open. The place is pretty amazing, and the views from the skywalk are no doubt unreal.

Surely the most breathtaking stop on this wonderful list of glass madness, the ‘Step into the Void’ experience in the French Alps gives tourists an unrivalled view of the Chamonix Valley.

The glass used to create the five-sided box is 12mm thick, can stand winds of up to 220km/h and is 3842m high on the Aigulle du Midi peak, with Mont Blanc nearby. 

The attraction opened late last year and it takes two cable cars to reach it. We imagine a fair few people bottle out before they get to the final view… 

glass_pavement_in_mountains_6

Sitting a spine-tingling 1,400m (6,233ft) above sea level on the side of the Tianmen Mountain, this glass walkway has got to be one of the least convincing structures included on our list.

When quizzed on the safety of the structure, a spokesman from the local tourist office stated that if hit by a falling rock from the mountain, the walkway is “designed to shatter but not break."

Somehow we don’t find that answer entirely convincing.

On the bright side, this is one of the more adventurous features in this post, and the photographs you could get would fuel your instagram for a lifetime. 

Willis Tower

Formerly the Sears Tower, and still commonly referred to as such, ‘The Ledge’ at Willis Tower was installed five years ago in 2009.

The three small glass boxes – which are 10ft high and 10ft wide – stick out on the 103rd floor of the building, meaning they look 412 metres back down to the ground.

The boxes can bear 4.5 tons of weight, although the laminated glass covering the floor of one of the boxes did shatter in May 2014 while a couple of tourists were sitting on it.

The visitors weren’t harmed in the incident, but we’re willing to bet they got out of there pretty quickly...

grand canyon skywalk

Probably the most famous inclusion on this list, the Grand Canyon Skywalk opened in 2007 and has pretty much been the source of mass social media spam ever since.

The see-through horseshoe bridge has a drop of 240m directly below it, but it sits a massive 1,450m above the bottom of the canyon floor – quite the height. 

Although we imagine the view from the Skywalk is decent, the third option that comes up when you start typing it into Google is ‘Grand Canyon Skywalk Ripoff.’

We're not telling you not to go there, we're just saying you may want to explore elsewhere in the canyon first before splashing your cash!

The Edge

The Eureka Tower looks down on Melbourne, Australia from a few metres short of 300.

The Aussie building is another that has opted for the ‘step into our giant glass box’ approach, but with their box stretching an impressive three metres out from the building, it’s certainly not an attraction you should snub in a hurry.

Aptly named ‘The Edge’, the box is situated on the 88th floor of the building, and you’re not meant to ‘ride’ it if you’ve got a fear of heights, are pregnant, or tend to drop sharp objects when you're fumbling around.

Glass Floor CN Towe

One of the first to get involved in the glass floor action, this 342m-high ‘don’t look down’ experience in the heart of Toronto first got going back in 1994.

The view of the Toronto Islands is pretty stunning, but arguably the better-known novelty at the CN Tower can be found in their glass-built elevators.

Glass was first installed in the lifts in 2008, establishing a world record for the highest glass floor panelled elevator in the world – a fairly specific record we think you'll agree.. 

It is a decent experience, but we think we'd have to choose the Chinese glass pathway or the Chamonix glass box as our ultimate my-my-god-is-it-time-to-panic-yet experience.
