The 3rd edition is the same size and format as the first two editions. Notes were updated and include details such as more new shelter huts, changed food drop facilities and the new section of track through Ellery Creek North.We have also completed a number of off-track walks in the area (Chewings Range & Mt Giles and Mt Zeil) and decided to not add these into the guide as it would have made the book heavier and would not be of relevance to most Larapinta Trail walkers. Instead we will publish those notes in another form, here are some basic notes for the Chewings Range. The Larapinta Trail guide has 160 pages, 121 colour photographs, 20 topographic maps (one for each days walk). This is an all colour production with full track notes for both directions along the trail. The colour topographic maps and notes have been colour coded for each direction to reduce confusion about which notes are currently being followed. Gradient profiles are provided at the same scale as those used in all our books. Each chapter describes a section of the trail plus the side trip to Glen Helen is included. The third editon has an expanded background section (4 more pages) which includes history of the area and notes on geology, climate, vegetation and wildlife. A comprehensive section on Safety and Trip Planning are provided. For the 3rd edition, we have reorganised the guide into 12 chapters to match the national park sections but retained the 20 one day sections within the notes. Of course many walk the track in less than 20 days wih 14 to 18 days being the most common. As I predicted, this walk has become a classic well-known walk as it traverses some excellent arid scenery. Water has been provided by park management at most of the regular campsites along the trail. For more details about the trail refer to my Larapinta Trail webpage for general information.
