Port Adelaide to Gawler.
A fun set of 111 geocaches along bicycle trails connecting the Port River Expressway, Northern Connector, and the Northern Expressway.
This series of caches highlights the 6km Port River Bikeway by the Prexy, the 17km Tapa Martinthi Yala Shared Use Path that runs alongside the Norcon, and the 23km Stuart O'Grady bikeway which parallels the Nexy.
You will have the opportunity to learn about some of Australia’s historically significant military battles that name the five main Northern Expressway Interchanges.
You don't have to do all 111 geocaches in one hit from the first to the eleventyfirst, but it will be a good ride if you do.
