I'm speaking about tourists who choose to spend their vacations (holidays) in places that push their limits to the extreme; such as the Antarctic, Mount Everest, pluvial forests, jungles, etc.
They're not your average tourist who looks forward to a relaxing week sitting on the beach, and soaking up the sun. These people are seeking ‘danger’ and thrills.
I've come up with excursionist. Although Oxford Dictionary didn't provide any definition, it lists several sentence examples, sadly, none of them seem to fit.
‘A good many of the excursionists were conveyed to the head of the lake by the steam-yacht ‘Swift,’ which made its initial journey for the season on that day.’
- What are these tourists normally called?
Idioms, and slang are also welcomed, but please say which region the latter is from.
