My 17 yr old son & I are planning a 4 day trip in early August - doing the 20 miles +/- from N to S. He is not interested in staying in the huts. I am looking for advice on where to plan our camping. We'll have a 2 man tent. I see some platforms and such, but are we realistic to think we can descend from the ridge trails each night and find either a platform or flat ground to pitch? We are thinking 7-9 miles a day max. Appreciate any advice.
