Why as a parking spot?, For several reasons. First, it is the ideal place to rent the boats that go to the island in the center of the lake, for they are closer to this than the people, you have to paddle much and take advantage of the time you pay for the boat on the island bathing you. Second, you stop the car and you can swim or take something on the beach that faces the parking lot. Third, if you go in camper is an alternative to camping next to the car park, as you can spend the night in it for 10 euros. The 10€ are from 20:00 am to 8 am, but I guess you can stretch more without being charged.
