The museum is super interesting and very well maintained, the staff is really friendly and helpful and they speak really good English. The entrance is free of charge and you can also use an audio guide for free. You can leave your luggage in the lockers or at the reception. We decided to go on the hike. It was rather easy even for me that I am not the best hiker, though we had good weather (cloudy but no rain).
It was overall a nice experience!
