Woman who's travelled to every country in the world explains how she got into most difficult and 'illegal' to enter

A woman who has visited every single country in the world explained how she got into the most difficult and 'illegal' to enter.

Lexie Alford - or Lexie Limitless, as she is better known online - became a Guinness World Record holder at the age of 21 after becoming the youngest person to travel to all sovereign countries.

Now 26, Lexie is sharing her experiences of travelling solo as a woman and detailing what happened in some of the countries she's visited.

On her journey to achieving the world record, Lexie experienced some difficulties getting into certain countries, with North Korea an obvious one that comes to mind.

The US State Department Travel restriction prohibits the use of a US passport to get into North Korea, meaning it's near impossible to get into the country.

"So North Korea was the number one most complicated country for me to travel to," Lexie told LADbible.

"I actually have a full YouTube video about this on my channel. But this particular time, and still to this day, being an American, going to North Korea is illegal. I was able to go via the Korean Demilitarized Zone [DMZ] from South Korea, but it took three trips just to make that attempt."

The DMZ - a strip of land that separates the two countries - acts as a border barrier between North and South Korea.

It represents territory on both sides of the border due to a ceasefire line that emerged at the conclusion of the Korean War.

With North Korea's borders closed to Americans, Lexie had to find a creative way to step foot into the country and break the Guinness World Record.

After many attempts to obtain an exemption to get in, the YouTuber settled on visiting the blue house conference rooms on the DMZ.

Lexie considered applying for a special passport and an exemption to get into North Korea, but these are typically reserved for the likes of journalists and humanitarian workers.

So, Lexie had no choice but to go with the conference rooms if she was to smash the record.

One half of the room is considered to be in North Korea, which Lexie was eventually allowed to step in.

"In no way at all do I feel satisfied with only being able to stand in North Korea for 5 minutes, but I'm grateful to have been allowed to step foot in the country to break this Guinness World Record," she explained on YouTube.
