We embarked on a king crab tour from Rovaniemi to Kirkenes, Norway. We took photos with freshly caught king crabs on the lake, then enjoyed incredibly fresh king crab at a restaurant – absolutely delicious! 😋 In the evening, we witnessed the aurora borealis in the suburbs – a truly breathtaking experience! Although the round trip was long, it was totally worth it! It was the most spectacular aurora we saw on our entire trip! I highly recommend double-checking the meeting time the day before departure. I received a reminder in my email, but I forgot, and ended up waiting two extra hours in the cold wind!
