Normally not, it´s not necessary to camp there. You can do the routes to Wilder Pfaff and Zuckerhuetl easily on one day. The upper Sulzenauferner is remoted to the ski resort and exposed to the storm. Wind speed more than 80 km/h are common. And in the winter the temperature goes done to -30° degrees. But it is defintely a good place to make a camp site.
Man ythanks and Cheers!
