#4 Igloos As Hotels? Hell Yeah!
Spending a night in an igloo is not an experience you can enjoy everywhere, but in Finland, you can. These are glass-walled igloo-shaped quarters situated amidst thick layers of ice.
However, the temperature inside is almost -3°C when it is -30°C or lower outside.
These are the ideal options to experience captivating modern lights. Moreover, spending a night or two in an igloo hotel is a time you will never forget.
