British freelance journalist Alex Hoban took these pictures while being chaperoned around the crumbling complex, situated 12km from the capital Pyongyang.
He said: 'My guide for the day insisted the park is open seven days a week and is always very, very busy, which is funny because when we arrived, the stagnant emptiness lingered in the air like a fart in a graveyard filled with the bodies of political dissidents.'
Mr Hoban, an in-house writer for alternative news website Vice, says he wasn't allowed to leave his bus until a group of North Koreans turned up to bolster numbers.
'It was only after about 20 minutes that I realised what was going on. These poor schmucks – or lucky schmucks, perhaps? – were wheeled out with strict orders to constantly remain 20 steps ahead of us and look like they were having A+ fun in the otherwise deserted park, lest anyone get suspicious that we weren't in Disneyland after all.
'Aside from us Western interlopers, they were the only people there. Strange task, but at least they were being paid a fair and decent wage to prop up one man's delusions of dictatorial grandeur.'
Attractions included a rather sorry looking flying carpet, a rudimentary 'coconut shy' using what appear to be tin cans and rocks, and a rusting Japanese bullet train ride.
The piece de resistance of the park was an ageing looped rollercoaster built under the supervision of North Korea's founding leader Kim Il-sung, which Mr Hoban couldn't go on until a man with a mallet had bashed in a few loose screws at the top.
Mr Hoban, who claims to have been held ransom and threatened in North Korea after previously criticising the government, said: 'It's a shame that North Koreans are treated by their rulers as basically being an expendable race of people.
'Before we were allowed on the ride, the cadres in charge sent a few terrified farmers on test runs like a shipment of human flour sacks.
'Luckily, they all came back in one piece, so they let us have a go.'
On another blog, entitled 'Cheating death at the Mangyongdae fun fair, Lindsay Fincher told how her shoulder harness was unlocked on the rollercoaster.
She said: 'I could basically just raise and lower it at will. Now, I actually love upside down rollercoasters, but that is usually when there are, you know, working safety harnesses.'
