There's nothing like a beach after a long, hot day of hiking. Especially since the turquoise waters of the region's lakes call for swimming. This equipped and supervised beach will allow you to cool off quietly. You will also find something to stay for the night, eat, fill your water bottles, go to the WC. A pleasant and practical beach.
