Park your vehicle near brooms head caravan park. Then just head west following the main dirt track. There is a heap of track in a 50 km raduis of the caravan park. Take plenty of water.
These tracks can suite both a little bike and an advanced rider on an adventure bike.
If you are on an adventure bike and want something a littel easier go about 70 km west of grafton to jackadgerry and the track is on southern side of the big bridge before entering Jackadgerry. You head north and stick to the tracks following the river . The jackadgerry caravan park is inetersting. They cook you dinner if you organise it in advance . Last time i was there they cooked rabbit. Cold beer and good people at the camp ground.
