Route questions, answered

Specific planning questions, with the scope of each source kept visible.

Which Castor start is shorter in the SAC listing?

The SE route from Quintino Sella is listed at 2:30–3:15 hours, versus 3–4:30 hours from Klein Matterhorn via Zwillingsjoch. Hut access and the return are separate.

SAC · Castor alpine route listings

Why compare cumulative ascent rather than altitude difference?

The WNW listing includes 560 m ascent and 270 m descent within the itinerary. The descent figure is not the return from the summit; altitude subtraction alone misses this terrain.
