Take the train until St. Moritz main station or park your car there and start the short hike to the lake. You will pass by the lake St. Moritz which in itself is already very beautiful and gives you an idea why this place is so famous. Don't forget to bring your bikini or bathing trousers since there are many wooden decks which you can use to access the lake, you will probably never swim in a more photogenic lake again. When the sun starts to go down the lake show itself from it's most spectacular site. We recommend to visit the lake in autumn since the trees will be yellow and make the lake even more special.
