There is a fun little ride you can do from Mapelton to Palmwoods. Descend down towards Nambour and turn right into Dulong road. Once at the bottom you need to remember turn right and right again at the 2 T- junctions to get to Palmwoods. Take a look at my map the road changes name a few time from the first T but it is pretty easy to find your way and fun to ride. At Palmwoods you may ride along the valley and return via Peachester or return to the top of the mountain again on the Palmwoods-Montville road.
I have removed the original post as it was too old, please see the map for location of this road.
