Russian bloger Sergey went to this island, and here is his story:
During 4 days on Wrangel Island, we have seen 169 polar bears. Sometimes they came very close to us, but no one was hurt. At the same time, neither we, nor our guides had any weapons, except a pepper spray and rockets that no one even used.
We followed the rules designed by the most authoritative and experienced Russian scientist studying polar bears – Nikita Ovsyanikov. Nikita has lived on Wrangel Island for several decades and has met lots of bears. He never carries weapons but has used a pepper spray 3 times.
I don’t know whether you’ll meet a polar bear one on one someday, but these simple rules can save your life when you meet any large predator.
