My brother and I did this a couple of months ago. We did it as designed as 4 days. The first and last days are short days. However, we also thought they were the nicest walking. We probably spent a few hours at Booloumba Falls and the Breadknife exploring the area. This was probably the highlight of the whole walk, along with Summer Falls and Mt. Allen.
Day 2 was the longest and least interesting. Mostly on steep maintenance roads with no views. Some nice rainforest type foliage though. Take care watching for signs for the tracks entering and leaving the roads as we missed one and ended up taking the long way around one section of road.
Day 3 was a mix of old logging roads and walking track. Good day and a really nice camp site at Summer Falls but still no real views along the way.
All the campsites were well constructed with nicely isolated camp sites. Alot of the wood treatment on the platforms was still sticky though from being in the shade constantly I guess. The water tanks were all fairly empty but with all this rain lately I'm sure they'll have plenty in them. There are a number of places to fill up at creeks aswell. There are photos and more details on my blog. http://seqldhiking.typepad.com/hiking-i ... -walk.html
