Grizzly is the highlight of the Mount Lennard mountain bike trails, part of the Wambenger trail network, in Wellington National Park, near Collie in Western Australia.

The trail starts from Lennard Road and descends from Mount Lennard adjacent to Pile Road and down to the lower trailhead, tightly weaving its way through the mature jarrah forest, and granite outcrops to provide spectacular views of the lower Collie River Valley

The average four percent gradient offers challenges for beginners to old pros with bermed turns and log rides for those who are up for the challenge.

Return along the Boylan Trail for a 12km loop. Both Boylan and Grizzly are rated Blue.
