Lago della Serraia is a lake in Trentino, Italy on the Piné plateau. At an elevation of 974 m, its surface area is 0.45 km2. A hiking path around the lake also circles Lago delle Piazze.[1][2] In 2007, the Mai Zeder running team held the third 24-hour ultramarathon, which started at Lago della Serraia.[3][4]
A decade-long water monitoring study, published in 2025, identified the occurrence of potentially toxic algal blooms in the lake, notably Microcystis aeruginosa.[5]
