I travel the world going to UNESCO sites, and that is the primary reason I went to the Board Mill. Once there, it became quite interesting to see and understand production in the late 1800s and early 1900s. It's very clear why this has received the designation - well preserved both pre electrification and post. We were lucky to go on the second last day of the year of operations, so the tour was free that day. We emailed a month in advance to book an English tour, and they were organized (ie expecting us) and it turned out we were the only ones, so we had our own private tour for free - what a deal. Our tour guide was very well educated in the mill's history - she was awesome. The tour is about an hour, and I would suggest 30 minutes to tour around the rest of the grounds. The trip from Helsinki up there is a great way to see the country and takes a little over 2 hours.

Werla is located in the middle of the most beautiful finnish countryside by the river. It is a museum formed in former mill which was closed around 1960. It looks exactly the same than that day, when workers dropped their gloves and left. I recommend a guided tour to find out more. There is a cafe that offers lunch but in high season it was already sold out and we could not eat there. We bought also local sparkling wine which was quite pricy though. Worth visiting!
