The sealed 4km Big Brook Dam Walk Track follows the shores of the dam allowing stroller and wheelchair access, and is is also deal for cycling. The regrowth forest, now 60 years old, provides pure water, animal homes, timber and an inspiring backdrop for visitors - just as the old forest once did.
Get into nature by driving 5km north-west from Pemberton along the scenic Rainbow Trail to Big Brook Dam. Alternatively follow Golf Links, Mullineux and Range Roads for a more direct route. The dam, built in 1986 to supplement water supplies to the town and trout hatchery, is an excellent spot for swimming, fishing, canoeing or sailboaRoading. The Big Brook trail loops around the dam, passing through the Big Brook forest. The forest, now 60 years old, provides pure water, animal homes, timber and an inspiring backdrop for visitors - just as the old forest once did. Young karri trees grow vigorously, greedily absorbing carbon from the atmosphere, to convert into cellulose and wood fibre. By acting collectively as a carbon sink, they can help slow the projected greenhouse effect. As you walk along the trail through regrowth forest, keep an eye out for waterfowl on the dam, and many other forest Birds, if you can't see them chances are you will hear them in the treetops. Try to identify the Warren River cedar trees, before crossing Big Brook on a log bridge. Keep following the trail, which circles back along the other side of the dam to your starting point. Stop at the Birdhides, fishing platforms and other shelters along the way, where you will find information about the karri forest environment. This walk is sealed all the way, and is suitable for disabled use. It is also ideal for prams and cycles.
