The Big Brook Forest is an area of tall Karri forest which has regenerated after being logged for its strong hardwood timber in the 1920's. The ride commences near a campground and arboretum and initially heads uphill along a gravel road. After reaching a bitumen road and open farmland, the route turns around and heads back into the forest along another scenic gravel road which follows the route of a former logging railway line. Most of the gravel roads in the area are made from laterite, known locally as "ball bearing gravel" or "pea gravel", containing round stones about 10 mm in diameter. So, apologies for taking it cautiously on the downhill section.
