Harlin to Brisbane Valley Highway Bridge via Yimbun Railway tunnel
After not being able to find the start of the walk to Mt McConnel, it was decided to walk part of the Brisbane Valley Rail Trail (BVRT) instead. Due to our location the Yimbun tunnel was a good option.
A quick google search found it was off Sinnamon Lane. Drove down this street to the quarry entrance. No sign of the BVRT! So we went to Harlin and parked in the vicinity of the sign at the location of Harlin Station. Heading south, the walk required negotiating fences and then the Ivory Creek crossing.
