Up to 1200 Harley Davidson motorbikes will be rumbling through Port Douglas on Sunday morning.

The 23rd National Harley Owners Group Rally kicks off at 9am in Cairns en route to Port Douglas via a quick detour through Mowbray.

Some traffic delays are expected and it might get a little bit noisy, but there’s a good chance this may be your only opportunity to see more than 1000 Harley Davidsons pass you by.

After riding through Port Douglas (see map) the rally will make its way back to the Cairns Esplanade.
