This business in Finland (there are about 10 operators running bear/wolf/wolverine photo hides) started from individual nature photographers wanting to shoot pictures of bears in the seventies. Bears come back to their kill (moose mostly around here) until it is consumed in full. So the logic step was to haul dead cows and hogs to the forest to play the part of the kill. Building a sturdy hide with a tall air ventilation tube to was the next step. So now we are here with commercial operators running a group of hides for paying customers. Martinselkonen can accommodate over 20 photographers/watchers in something like 8 separate hides. One is a big hide for about a dozen people, other ones closer to the animals are for max 2 people. There is a dry toilet bucket in the hide, but no privacy (big hide has a curtain around it). It is not possible or recommended to exit the hide during the night. The guide comes in the morning to take the customers out after the bears have left.
Dog food is a convenient bait as it is easy and cheap to get, you can not see it in the pictures and it is quite healthy also. In Finland, in contrast with USA and Canada, we have never had problems with bears breaking into houses or even tents. We do not use food containers when camping in bear areas, there are zero cases of bears getting into tents or molesting campers, zero. They are still afraid of people, which is good. By the way, dog food used as bait for the bears is not stored in the hides! That would surely pose a danger to the bear watchers.
It is a good question if having something like 12-15 bears living in an area of few square kilometers is natural or a good thing. At least the place is far away from any villages. Still, the animals are wild, even if somewhat used to people, or at least the guides who handle the food distribution.
My trip was a birthday present from my brother. It is possible to contact the place directly through their web page at

It is up to the each individual to consider the ethical side of things. Getting a good picture, any kind of picture of a brown bear, at least here, just by hiking around is practically impossible. I would say 99.99% of bear pictures taken or published anywhere are taken from hides like this. Some photographers are open about it, others are not.
