Place is very nice and located in beautiful landscape, what is making wildlife observation even more fascinating.
We were really lucky and we saw 6 wolverines! Not so many birds as expected, but our main goal were wolverines. After whole sleepless night in one of three hideouts (hot and full of mosquitos), it is a good feeling to have some pictures of this interesting animals.
You can see them here.
Most of them were taken with Nikkor 70-200 f2,8 borrowed by friends. Setting the tripod was a bit challenging, but even for this you can find the solution. During summer time, the darkness is not a problem, since days are really long. Nonetheless higher ISO possibilities might be useful.
There are 3 professional hideouts (one with higher standard). It is possible to visit them during winter during the days and in the summer for the nights. Erä-eero is described as one of bests, if not the best, places for observing wolverines. If you are looking natural habitats, where you want to see them, Erä-eero is perfect. Link for their page you can find in previous post.
