To get to this spot you have to go with your car to the Grimselpass and from there take a narrow road that you are only possible to access every certain period of time, since they don't want to have cars coming from both ways, since the street is to narrow. After some turns you will start to see a lake bellow you and then you have to keep an open eye for a parking space, since there are not a lot. Then it's just a 5 minute hike down to this amazing place where you get views like this. Sunset and sunrise are nice at this place, so if you want to catch both there is the Berghaus Oberaar.
