When you come out of the large parking lot, go up the narrow stairs on the left-hand side. At the top, take the first turn to the left, follow the road and the entrance to the beach fields will be on the short side of the square.

When you are in the atrium and go through the yellow exit, turn right and follow the road. At the next opportunity, turn left and then take the next street on the right. Follow the road and the entrance to the beach fields is on the left-hand side, right next to the parallel building.
