There are Ferris wheels all around the world, but Finland has a very Finnish take on the classic amusement ride. Finns love their saunas and coined the word. If you visit Finland, you'll have many opportunities to experience different types of saunas, including one that will give you a scenic view of Helsinki.
The SkyWheel allows you and up to four friends to languor in the steamy heat of a private sauna gondola as it rotates through the wheel. There's also a hot tub at the base of the wheel. The experience is a bit pricey with prices starting at about $280 USD per hour.

But if you have to book an hour at a time, it would probably kill most Americans.
