2 pitches. The crack up the centre of the south-east face of Torre Piaz gives a fantastic pitch. The climb has loose rock in places, though very well protected.
From Alpine Club Guidebok update "Torre Piaz 2670m (now 2660m). A rockfall in 2004-5 has removed the entire Eastern side of the Torre Piaz/Piz Piaz. This is very evident when at the start and climbing the initial pitches of Torre Delago's SW Arete (2.7a). The tower fell 200m into the lower NW combe. This has entirely placed the North Crack IV+ - 2.6a(iii) to the history books and affected Via Rossi (SE Face) - 2.6a(ii) which no longer has the final short summit pitch but loose yellow rock (best avoided) to finish"
