About 40 minutes from our house is the spectacular Rheinfall. The River Rhine pounds through here. In the photo above you can see a small island in the middle of the falls. There is a dock at the base of the island and when the water volume is a little less you can take a boat to there and climb the steps to the top. It must be incredible from up there.
The water is crystal clear (are there any rivers/lakes in Switzerland that aren’t???) so you can see everything below. There is an abundance of fish in the river. It was fascinating to see some of them trying to swim against the pounding water.
