A bridge crossing in China gives adrenaline-junkies a run for their money with the serious vertigo-inducing challenge.

The red painted steel bridge has no railing, glass or safety net to protect from falling in between the rungs. Aside from a zip line, the only thing that lies between crossers and the bridge is frightening altitude.

In a video two bold adventurers decided to cross and have hilariously different reactions to nearly walking on air.

Dare devil! A young girl crossed this bridge hundreds of feet in the air in China that has no railings, glass, or safety net in seconds, championing the terrifying, vertigo-defying challenge

Don't look down! This woman can't help it because in between the rungs of this rickety ladder, there is nothing but pure altitude. Tracking each step carefully, she made it across safely

A young woman faced the challenge first. Fastly attached to a zipline, she crossed the ladder bridge that connected two mountain ledges with confidence.

The young girl stepped boldly onto the bridge and crossed like she would any other bridge. She showed no sign of fear and her knees never gave in to the fright of the height. She stood up the entire way, her eyes glued to the ladder to track each next step.

But her confident stride didn't last so long. Vertigo eventually hit the girl who paused for a moment near the end of the track. She swayed slightly and stared into the massive depth of the canyons below her.

A breath later she collected herself and made it safely across, all within a matter of seconds.

Another bridge crosser, however, did not have such luck in keeping his head held high, or up at all for that matter.

The young man who followed the girl hilariously succumbed to fear and a case of the shakes right after his first step, and it was all caught on camera.

Scaredy cat: A man followed the woman's courageous crossing, but he could not measure up and began to scream wildly and shake uncontrollably after his first step on the bridge

Holding on for dear life: The man decided to crawl his way down after his knees betrayed him

After just one step the man began to yelp and shake uncontrollably in fear. He continued on, screaming 'This is too tall! F***! I'm so scared!' with every single step.

By the third rung he abandoned efforts to walk upright and sunk to his knees and decided to crawl across.

Commentors on the video dubbed it a 'Gollum' walk as the man crawled across rung by rung.

At one point he gained an ounce of confidence and began to rise, but realized he acted too soon and went right back down. The man hilariously never stopped screaming and swearing and at the end sped up his crawl to Spiderman speed to get the challenge over with.
