Nice view on these for me unknown summits! And they look fine!
They sure look fine! Gatterspitze can be reached by an easy trail from Kartitsch, the same that ends at Obstanser See, Cima Frugnoni and Pfannspitze. Of course, you need to turn west, before you reach the lake, directly after you reach the little Prinz Heinrich Chapel. We didn't do the hike since we had done the Gr. Kinigat, Pfannspitze double pack with 26km and 1600m elevation gain (said my GPS/altimeter). After that we didn't want to return into the valley ;-)
