i would like to experience the climate of the arctic islands because it is rather severe and i can easily test my fortitude. it is very amazing to experience the polar day and the polar night. i would like to watch the sun beautifully shining onto the fjords, covered with fog or ice-covered mountains reflected in the lake. i would like to see spitsbergen with its bird cliffs of 100m high and running for several kilometers. here i will be able to experience the awesome beauty of the arctic and see its fauna. i would like to watch the local fauna: whales, guillemots, seals, polar bears, walrus, reindeer and arctic foxes. i think that the arctic islands are the unique place on the earth where you can feel the real frost. i would like to travel to the arctic islands just for a few days. i think i will have a merry time and i will get acquainted with the nature of the islands.
