Travel tips

A relaxing introduction to Finland could be indulging in a traditional Finnish sauna, so get those toxins out with a visit to Kotiharjun, the only wood-heated sauna in the city. 

For some uniquely Finnish history, check out the Sibelius Monument, located in Sibelius Park in central Helsinki. The surreal design was unveiled in 1967 in honor of the famous Finnish composer Jean Sibelius. 

To see some of the Finnish art scene, check out Kiasma, the Museum of Contemporary Art, for all the latest trends and exhibitions thereof. Even the building itself is a work of art, and well worth an afternoon visit.

You could simply change planes and be in and out of the airport in under an hour, but you could also do a stopover on our island for anywhere from 1 to 7 days, at no additional airfare. You will have the opportunity to explore Iceland's geyser, waterfalls and caves, and to visit the charming capital of Reykjavik.
