Hamhung (함흥시, 咸興市) is in the Donghae Coast region in North Korea.
As with anywhere else in North Korea, getting into the city will be only possible as part of an official organised tour. Apparently some tours do include Hamhung on their itinerary.
Hamhung Grand TheatreThe largest theatre in North Korea
Hamhung Water ParkApparently covering tens of thousands of square meters, this water park comes equipped with several slides, indoor swimming pool and indoor wading pool.
Throughout Korea (both North and South), the special tangy version of cold noodles known as raengmyeon (랭면) is famously from Hamhung.
