Himalayan high road

The Great Himalaya Trail is the longest and highest alpine walking track in the world. It traverses more than 4500 kilometres from Namche Barwa in Tibet to Nanga Parbat in Pakistan, winding its way through mountains and remote communities...

British mountaineer Robin Boustead has spent the past seven years documenting the trail and in 2011 he will lead the inaugural World Expeditions trek over the full distance.

The truly adventurous can do the entire 150-day trek; others can opt for one of seven stages from 18 to 35 days.

Boustead, who has been trekking in Nepal since 1993, completed the full traverse over two trekking seasons in 2008-o9 and recently published The Great Himalaya Trail - a Pictorial Guide.

The trek will start in Kanchenjunga in the far east of Nepal on February 15. Trek segments cost from $2800.

Boustead will be talking at an information night at World Expeditions, 71 York Street, Sydney, at 6pm on Tuesday.
