A new guidebook for our favourite trail in Australia.
The Overland Track: Cradle Mountain to Lake St Clair
by Warwick Sprawson
details on Red Dog Books. ($39.99) Check also the website for the book.
Just the other day I recommended the classic hiking guidebook for The Overland by Chapman. About half the price.
On the other hand, this new competitor by Sprawson garnered some praise from Frank in Oz. His site is definitely the best source of information on the Overland, online.
In fact, you might simply want to download Frank’s Overland eBook, and refer to that PDF from your mobile device. It’s also less expensive than Sprawson.
All good options.
Check our Overland Track information page. It’s one of the top 10 treks in the world.

I have used all three books for walking the Overland, and all have their respective strengths. Chapman´s is basic point A to B advice, the Ebook has information on what to bring while Sprawson´s is more comprehensive, detailed information on the plants, animals, birds and history (as well as a fold out map) satisfying the more curious, but costs more.
Which ever book you take, the Overland really is a world class track, best walked in January when the days are long and many of the alpine plants are in flower.
