Hi Selwood
My first bit of advice is if you've only got 4 days, I wouldn't be contemplating a traverse of the Du canes if you want to overnight on Ossa as well.The two times I have done the traverse, I have taken 5 days from Narcissus.Admittedly, this did include side trips to all the surrounding peaks (walled,eros,hyperion,geryon) but to do just the traverse still would have taken 4 days. Coming in from Arm River, this is at least a 5-6 day trip
From Du cane gap to Massif is a full but comfortable day. Navigation is straight forward in fine conditions but would be trecherous in white out, particularly trying to find the drop off onto big gun pass. A pack hauling rope may be useful but I didn't find the need for it. The only really tricky section where it might come in handy is negotiating the (very) large boulders just before the summit plateau. Camping is limited between Castle Crag & Massiff. It may be possible to camp by one of the small tarns along the ridge but I wouldn't depend on it. The best sites are in the "bowl" on the summit of Massiff. Depending on how far you want to get, again, it is a full but comfortable day to get to the Labyrinth.
While it's not exactly encouraged, there are no rules to say you cannot camp on Ossa. The best site in fine weather is by a small tarn about 200m down from the summit. From Pelion Gap to the summit without a pack is 60-90 minutes. I'd say you could double this with a full pack on your back.
I'll probably get shot for mentioning this, but an excellent alternative 4 day trip is to continue along the ridge from Ossa to Thetis and on to camp by Leonards Tarn. There's a lot of boulder hopping,scrambling and scrub involved, but no worse that you could expect on the du cane traverse and Leonards tarn would have to be one of the most sublime campsites I've had. To get out, go back over Thetis to Paddys Nut and pick up the old track to Pelion Plains.
