541 feet of plastic pullin’ was made possible with the construction of the Diga di Luzzone, a dam in the Ticino district in Switzerland. It’s five pitches, making it the largest artificial climbing wall in the world. No approach, well protected, and even a restaurant at the base. The Swiss did it right.
A 50 meter rope is plenty. As the angle increases, so do the grades: 5.7, 5.8, 10a, 10a, 10b.
