Kennedys Bush is a grassy 4WD track. It is steep and can be rutted in some places.
There are two options for getting to the start of this track. One can either bike up the Crocodile Track , or ride up Kennedys Bush Rd.
Starting from the gate at the top of The Crocodile ( or from the end of the sealed road ) there is a piece of single track that snakes up the hill to your right. This single track rejoins the track futher up, and is more fun than taking the farm track.
After the single track is exhausted, continue up the track untill the Summit Road is reached, simple.
At the West end of Cashmere Rd turn left onto Kenndys Bush Rd. Cycle up the sealed road until it turns into a grassy farm track. Follow the farm track as it climbs up to the Summit Rd.
