After the rocky entry hike and its tiny brook, we finally made it to the lake: Ibon de Plan. Only a handful of other folks were there on this weekday, whereas weekends can be much more crowded. Mrs Z and I saw clear evidence of this being a glacial valley. Mother Nature and her moraine had gouged and carved the terrain of Cotiella Mountain (2912 m) into artistic stony striations. The legend: a Moorish princess from long ago will dance above the water at sunrise for any who sleep shoreside.
