The 3,273 m high Collaspro dominates the panorama of Lake Anterselva and is part of the Vedrette di Ries-Aurina Nature Park.
Not far away from the highest peak of the Rieserferner Group - the 3,436 m high Collalto, or Wildgall in German - the approx. 150 m lower Mt. Collaspro is located. The mountain is part of the main crest of the Rieserferner Group and is surrounded by the Eastern Rieserferner Glacier in the north and west. A neighbouring peak in the southwestern area is the 3,097 m high Cima di Pianalto. Among the peaks of the Rieserferner Group, the Collaspro is considered to be the most difficult accessible summit. The first ascent was done by Victor Hecht from Prague and the two mountain guides Johann and Sepp Ausserhofer from Riva di Tures on August 18, 1872.
Back then, the route proceeded first towards Mt. Collalto until the Forcella Nera gap (2,981 m a.s.l.), and then towards south-west via the Collaspro north ridge up to the summit. But the alpinists failed because of an impassable section and had to turn round. The second try was successful and they reached the top due to a further western ascent through a 45° sloped ice rut. Still nowadays this route is the normal ascent to the summit (difficulty level III, UIAA), leading past the Roma Mountain Hut at 2,276 m a.s.l.
