From the Sign of the Bellbird car park, take the Crater Rim Walkway to the right of the car park entrance. After 5 minutes you'll reach the start of the Cass Ridge Track.
The track follows a gently sloping grassy ridge to near the southern boundary of Ohinetahi Reserve. It's worth taking time for the short diversion to admire the impressively forested Cass Peak gully.
Combine Cass Ridge with O'Farrells track, Bush Road Track and Ellas Track to make a diverse 3 hour walk.
The tracks in Ohinetahi are managed by the Summit Road Society(external link). You can find maps and more information about the area on their website.
