Cycle Trails around Australia is an interesting website outlining what the website writer describes as:
12 epic bike adventures in Australia with an in-depth, full-on, all-you-need-to-know, but not-complete-hand-holding, and somewhat informal, guide to the local trail conditions. Well, at least most of the useful stuff. Yay! There’s even answers to those usual questions mum likes to know.
Well, there are 12 bike rides listed on the website and there is details on the ride options with a focus on off-road riding. From a WA perspective the website lists the Gibb River Road, Karijini National Park and the Munda Bibbi Trail.
A good website to start with and to get ideas for the next Aussie bicycling tour. Gibb River Road here I come
