Regardless of how it first came to be called Hell, the name stuck and the area has become a tourist attraction, featuring a fire-engine red hell-themed post office from which you can send “postcards from hell”, and a gift shop with “Satan” Ivan Farrington[1] passing out souvenirs while greeting people with phrases like “How the hell are you?” and “Where the hell are you from?”
Really, I think that the bigger question here shouldn’t be “how would you turn Hell into a tourist destination”, but rather “how would you avoid overtourism in Hell?”
In the Hell of the US you can even become the mayor for a day

Apparently, Hell, Grand Cayman is also doing well on the tourist front:
