This lake is truly magnificent! Its dark and smooth water offers a mirror effect of the entire surrounding landscape, and its rocks in the water enhance this picture! A top spot, it's just a shame it passes so close to the road, although it wasn't very busy when I went, and the presence of the parking lot could bring more motorists, I imagine. When I went there weren't too many people, but given the less than ideal weather, maybe it's not always as good!

Lake Merle is a very beautiful stretch of water where it is good to stop for a shaded picnic.
