It's entirely possible though? Surprised that people don't know this.
You of course need to follow some strict rules and can only go see the government sanctioned sights and tours. From what I remember it's a lot of propaganda monuments and some caves.
Just behave and it's not really risky or anything. It does sound pretty dull to me though.
I would argue that travel to North Korea - the world’s most repressive totalitarian state, with a lengthy history of violent subjugation - is inherently risky.
I feel like a lot of people here assume that you're going to be automatically arrested when going to DPRK but it's not completely true. You can get easily arrested and you have to follow strict cultural/government imposed rules.
The DPRK previously has done a "put it's best foot forward" and keep tourists in a bubble where you're not allowed to take pictures or videos unless in specifically permitted zones. It's essentially a propaganda tour.
So you definitely can go to the DPRK as a tourist but for the love of god follow their rules to the letter.
I'd personally never go but there are people who do war zone tourism. I could see why a person would want to experience a full on propaganda tour made by an totalitarian regime with all those cold war era propaganda art.
There's a reason to go there other than to say you have, but it's not worth the risk for most people IMO.
