Svalbard is a rugged area and parts of it can barely be accessed. The best way to see it is by boat.
It’s especially good in summer when the sun does not set. Thanks to the midnight sun, it will be light 24/7. The light is very delicate, perfect for taking photos.
While on the cruise you can take several excursions to disembark and see animals, such as the walrus. You will also make stops at quaint (Russian) villages such as Barentsburg.
There are lots of options when it comes to cruises, you can go for a few days, but also a week. Make sure you have a look at which route it will take. If you’d like to see polar bears, it’s best to take one that passes Svalbard on the east side.
