Alligator Creek flows through Bowling Green Bay National Park in a series of cascades, deep pools and waterfalls.

The walk starts from the southern end of the picnic area. A lower lookout is located 500 metres along the track. The track continues on another two kilometres to Cockatoo Creek. "Flat Rock" is an ideal place for a rest and a swim. From Cockatoo Creek the track then meanders roughly parallel to the creek, following powerlines, through open woodland forest to Hidden Valley. Across the creek the valley narrows, with Mount Elliot and Saddle Mountain framing the landscape. The track follows a series of steps ascending through a rocky vine-thicket (some rock scrambling required) and suddenly arrives at the falls. Access to the waterfall is not possible.

As the walk is long, visitors are advised to commence walking in the morning to allow time to safely return during daylight hours. Carry water and wear sturdy footwear. In order to get to the falls, visitors must cross the creek on four occasions. These crossings vary in depth from ankle-deep to approximately waist-deep, depending on season and weather conditions.
