After morning pickup from your Interlaken hotel, travel about 20 minutes in a climate-controlled minivan to Lake Thun.
Make a short stop at Neuhaus beach on the shore of Lake Thun. Waters from streams in the Oberland and Lake Brienz to the southeast feed into the bright blue alpine lake. You can also purchase a coffee or ice-cream there.
Continue to a farm located near the picturesque village of Wilderswil. Take in the postcard-perfect Swiss chalets as you approach the dairy farm, then meet the farmer for a tour that includes viewing the cows and other animals.
Your final stop is Lake Brienz in Bönigen. The lake measures nearly nine miles (14km) long and sits in the Swiss mountains. Enjoy sweeping views from the viewpoint before returning to your hotel in Interlaken in the late morning. The tour can accommodate a group of up to 13 people.
