No access. Everything closed

When we arrived the reception was closed although it was supposed to be open between 9am and 7pm. You could call a phone number. We couldn't go there, you had to make a reservation..... The lake was dry and I saw many houses in the distance. It didn't look appealing.

When we drove past it turned out that the lake was empty. It was like a desert in the valley. There was no one at the reception. We drove through..
