Over the years there has been the odd reference to, or discussion, on these forums about Bruce's Walk in the Blue Mountains. I have occasionally poked about bits of it, sometimes incidentally. On the weekend I had an epiphany and decided to start exploring the track more fully. Reminiscent of "the olden days" I left the car at home and caught the train to Wentworth Falls. I then completed the section of the track to Lawson from the access point at the end of Lawson View Pde. Albeit I went in the opposite direction of travel to what appears to have been originally recommended in 1931. A nice mini adventure that I completed in a few hours (YMMV), occasional ricketty ladder and steep, loose descents/climbs notwithstanding. I had little trouble navigating despite the absence of any signage. Unfortunately the original line of the track has been altered in places by development etc. I did have maps, both paper and online, but used no other navigation aids. There are often small markers on trees, which help through sections of deadfall etc. And you do have to hunt around the Kent St fire trail (complex) for the last short section into North Lawson. Finding that then allowed me a short side trip into Dantes Glen to finish before walking out to Lawson railway station.
After returning home I continued researching the track with a view to eventually completing the rest of it. I already own some documentation courtesy of a later edition of Jim Smith's guidebook, but noticed this post with Roger's reference to "The New Walk across the Blue Mountains", published by the NSW Railways Commissioner, price 1/-.
Discussion suggested availability of copies from the National Library and perhaps other sources. But I was delighted to find that this historic booklet is now out of copyright and can be downloaded free from the National Library:
