Great experience for nature lovers
Definitely worth the hike, the view is great, the Shabin well equipped, and you are truly in the wild (we even went face to face with a moose).
I would however insist on the fact that the hike to get there is no joke, if you plan to go there I would highly recommend to pack lightly, and make one trip with all your stuff/food. I would advise inexperienced hikers to get some good gear (at least backpack) and seek for advise from the owner. Ask Olof for more information about the trail, the equipment already up there or anything really, he is a great host. But keep in mind he is also a world class athlete, him being able to do the trail barefoot does not mean you can too (learned that the hard way).
I would highly insist on starting the hike way before night (like 4pm max for the summer).
But if you are up for the challenge go for it, it is absolutely worth it. I would recommend to spend 2 nights up there if you can carry the food for it, so you have time to explore but also to rest.
