The Munda Biddi Trail Foundation Inc is a not-for profit organisation that assists with developing, promoting and maintaining the Munda Biddi Trail - Western Australia's world-class, long distance, off-road cycling trail.

Starting in Mundaring in the hills east of Perth, the trail meanders through scenic river valleys and the magnificent Eucalypt forests of WA's South West. The Foundation enlists members and volunteers to assist in maintenance of the trail and organising trail and community events.
