A very nice cultural, historical ride with fast sweeping sections after Fiskars and the last section into Lohja with it's fantastic curves humps bumps and even a Jump (not recomended, I was going too fast. Dooh!)
As it is a very touristic route there are often police around during the holiday season. Be warned.
This route, a half-day trip, runs through the oldest industrial villages in Finland. Famous are the names like Billnäs, Fiskars, Antskog and the town Lohja. You may stop specially in the village Fiskars - Fiskari which is now (after steel industry's collaps in 70's) a centre of handicraft and modern art with many attractions and very nice historical environment. The whole road line from Karjaa to Lohja is mostly original and due to this, very interesting to drive. The length of the route gives some extra bonus for the day. There are quite different road profiles to drive, either slowly or more aggressively in uninhabited sections. There are many villages to stop for eating and to see countrylife in Finland. The last 17 km long section from Myllykylä to Lohja is named as one of the most beautiful roads in Finland. This whole route can well be combined with the Inkoo - Karjaa route, the both having about the same shape and spirit.
