The Munda Biddi Trail is a long-distance mostly off-road cycling trail in Western Australia. It runs for over 1,000 kilometres (620 mi) from Mundaring to Albany. The completed Munda Biddi Trail opened end-to-end in April 2013 when it claimed the title of the longest continuous off-road cycling trail of its kind in the world.

The track traverses vast areas of unspoiled forests and bushland with mostly gentle terrain.

The record for completing the Munda Biddi Trail (South to North) is two days, seventeen hours and 22 minutes, set by Craig Wiggins on 25th October, 2020. Sections of the trail vary in terms of their difficulty and terrain type but it has stages suitable for everyone’s cycling ability and pace.

The trail is easily accessible by car, and riders can begin their journey from multiple locations. There are free campsites at various points along the trail, some with more than a day’s ride between them.
