Guess what, it's going to rain in the afternoon. I had an early start and headed for the Thurfälle. I took the train to Wattwil and then the bus to Unterwasser, Post. From there it's a 10 minutes hike to the falls. Just follow the sign "Weg des Wassers".
After the falls, I continue the "Weg des Wassers" till I got to Gamplüt. From there I took a scooter to have an easy descend to Wildhaus.
