A walking path from the station heading to Bachalpsee is an easygoing hiking trail. It was a well-kept walkable path, but it was mostly uphill and it continued all the way to the lake. It was actually harder than it looked!
After 1 hour's walking, at last I came to Bachalpsee(2265m).
There were two small lakes and I heard that the big one was the lake "Bachalpsee", but I couldn't tell which lake was "Bachalpsee"....
When there is no wind, you can take a great picture with the snowcapped summits reflected in the water.
