It's the stuff of Hollywood movies – dangerous, primitive bridges like the one above in Pakistan, swinging high over a jungle valley or a raging river. Sketchy, scary and a little bit exciting, walking over one is a leap of faith. We've gathered up some of the world's most fear-inducing bridges to give you daydreams – or nightmares.

Take a trip through the trees in India
We're starting off simple – this sketchy-looking bridge is probably one of the safest you'll see in this list, given that it's part of a hotel in India. But probably best avoided if you've been indulging at the hotel bar.
The Hussaini Hanging Bridge, Pakistan
This bridge? Not so safe. In fact, the Hussaini Hanging Bridge in Pakistan is known as the most dangerous bridge in the world. And it's not difficult to see why. Every step requires a leap of faith. Whoever designed this needs to go back to engineering school. But if you like high-wire thrills, pick up a plane ticket – this is only one of many precarious rope bridges in Northern Pakistan.
An 'indo' board bridge, Indonesia
Surfers and skaters will be familiar with the famous 'Indo Board' balance trainer – but how would they fare on this hanging-by-a-thread bridge in Indonesia? As for these kids – don't worry, they're just on their way to school.
A walk and a hike, Western New Guinea
This suspension bridge above the rapids of the Baliem River goes not only across – but up, as well, meaning there's two ways you can miss your step.
Shaky steps over the rainforest, Brazil
This bridge may be part of a jungle ropes course in Pirenopolis, but there's no question it will make your legs tremble – those steps in the middle are actually meant to be free-swinging.
A scary selfie, Kashmir Himalayas, India
Our applause goes out to the individual who took this shot. Crossing a bridge like this and then also feeling confident enough to stop and take a shoe-selfie? That's bravery.
Stepping over space, Austria
Not every sketchy bridge is in the middle of a jungle in a developing country. This pulse-quickening traverse hangs above a healthy amount of alpine air in Austria.
Cirrus business on Mt Nimbus, Canada
This high altitude suspension bridge on Mt Nimbus is a bad-joke-teller's dream. But with such sketchy footing, it's best to keep your head out of the clouds.
Making it over the Mekong River, China
The Mekong River travels through six different countries in Southeast Asia – China, Burma, Laos, Thailand, Cambodia, and Vietnam – and offers conditions from gently moving water to frothing rapids (as pictured above.) We're guessing most people want more than two skinny ropes to cross it – but this individual seems to be doing just fine.
Trekking Everest, Nepal
These bridges are hardly permanent – every year they're put up by Sherpas to help Everest climbers navigate the incredibly dangerous Khumbu Ice Fall. It's one of the most treacherous parts of an Everest attempt, where precision footwork is required while wearing crampons with a heavy backpack on your shoulders.
