Lovely lake with a fireplace and a rest stop as well as a good place for a swim. The northern lake of the two is accessible by a marked path from the main hiking trail. There are benches and a fireplace here as well as easy access to the water for swimming.
Keep in mind that there is a recycling plant or garbage dump just 200m north of the lake. You can't see it, but you can regularly hear trucks during their working hours and I would probably avoid drinking the water. I didn't notice any smell when I was there, but that may depend on wind direction.
