I have walked the Track twice with Ultimate Hikes Guided Walks and still rate it one of the best Walks I have ever done.
I shared the experience with friends on both occasions and we had good weather that included snow on the Mackinnon Pass on the 2nd occasion
Both my trips were in November and the only downside was the Sandflies that pestered you (take bushmans deet if you can cope with it )
The track can be very wet and dangerous if you are on your own so I can heartily recommend the Ultimate Hikes Guided Walk for the ultimate in 5 star hiking!!!
