We plotted out a trip that gave us as much "off-bitumen" driving as possible and kept us "as far from the madding crowds" as possible without going too far from home (Sandgate) or becoming a road bash. Left home via the back roads to Barakula state forest, the largest State forest in the southern hemisphere (
http://www.derm.qld.gov.au/parks/barakula/index.html). More or less had it to ourselves. Camped on Dogwood ck bush camp. 1st 2 pics below. Must be 1000 km or more of tracks available in the forest for "wheeling" as our Nth Am friends call it.
After 2 days there, we went through to Auburn R nat pk (next pic below) and had a great walk there, then on to Tolderodden Conservation Pk (4th pic), Jack Smith Cons Pk, Boat Mtn Cons Pk and then Brooyar state forest (camped at Glastonbury ck camp, last 2 pics), then back to Brissie via tracks through Wrattens Nat Pk (which is where those pics of the land slip were taken), Yabba & Jimna state forests. Final pub lunch at Kilcoy and then home. Just under 1100 km in the 6 days.
