I have done the Kosciuszko walk, commencing at Charlottes Pass, resting at Seaman's Hut then up to the top and down to Thredbo. in February 2005.

Best views to the Victorian southern alps.

Take snacks, water and a warm jacket as the weather can change ( even in Summer).

I didn't take the Blue Lake trail.
The Summit walk, past Ramshead Range to Eagles Nest , down to Thredbo

Thanks for your comments Gloria. I really wanted to see Blue Lake but didn't realise it was on the Charlotte Pass trail. Will have to go back and do this one another time.
