Moment black bear approaches group of hikers, sniffs their hair and even poses with them as they snap a selfie - before it calmly wanders off

A group of hikers kept their cool and even managed to snap a selfie when a curious black bear approached them along a trail in Mexico. 

The unusually close brush with nature reportedly happened at a popular hiking trail at Chipinque Ecological Park in San Pedro Garza García, according to a person who shared the video. 

Footage shows a woman standing very still as a black bear perched on its hind legs approaches and sniffs her.

Behind her, two other female hikers manage to remain calm as they watch the bear inspect their friend.

The bear briefly drops onto the ground, but suddenly lurches back onto its hind legs again  and presses himself against the woman. 

Bystanders try to distract the black bear, but it is preoccupied with sniffing the woman's head. 

Meanwhile, the woman quickly seizes the unbelievable moment and pulls out her cell phone to take a selfie.

As if on cue, the bear stands just long enough for the picture before dropping back on all fours and lightly swatting at the woman's legs twice. 

The black bear then begins to wander away, while the woman and her friends speed out of the area. 

The shocking moment was shared to social media, where it amassed more than two million views since Saturday.

Former NBA player Rex Chapman shared the video on his page and wrote: 'Oh. my. goodness. She’s a rock. I want this girl in my foxhole...'

Journalist Yashar Ali shared a similar sentiment and praised the group for handling the situation with ease.

Clarence Hill Jr. 'It's one thing to be brave, its another to be poised under pressure. My God'

'We don't see the lead up, but they handle themselves well. If a black bear is this close to you, it's too late to scare them off unless they're attacking you, then you should fight back,' Ali wrote.

'Otherwise, stay calm..don't run. Don't do that with a grizzly if they attack you...play dead.'

Fellow journalist Clarence Hill Jr. added: 'It's one thing to be brave, its another to be poised under pressure. My God.'

The user who shared the video noted that it wasn't uncommon to see black bears in Chipinque Ecological Park, and it's certainly not the firs time it was caught on camera. 

Last December, two  black bear terrified a visitor in the park while sniffing around garbage cans for food.
