If you are heading South on the Munda Biddi Trail, and you have ridden into Collie and don't want to return the same way, you can use my short cut to rejoin the MB from Collie. It is 14km long, and easy riding. I call it the Karak short cut, as it follows the Karak Trail out of Collie. I started at the Visitor's Centre, which is the new Trail Head. Follow the cycleway next to the Coalfields Highway West until it turns into the Karak Trail. This lovely little trail goes through the bush and a stand of paperbarks. The Karak trail stops after leaving the bush, but the walk way continues into Allanson, as small town just out of Collie. In Allanson, join Railway Parade. Turn right into Worsley Back Rd (signposted) and follow this road to rejoin the MB at the railway crossing. The road is a bit hilly, but similar hill sizes to the MB, and the firm, good quality gravel road makes for easier riding. Worsley Back Road is shown on Map 4.
