Cowan Creek is a tidal tributary of the Hawkesbury River located within Ku-ring-gai Chase National Park, approximately a 45-minute drive north of Sydney. The creek offers a sheltered paddling environment characterized by relatively narrow confines and numerous inlets to explore, which are often described as a delight. A primary and well-regarded access point for paddlers is the canoe launching area at the southern end of the Bobbin Head Picnic Ground, providing smooth entry to the water. Other boat ramps exist within the creek at Akuna Bay and Apple Tree Bay, the latter being a three-lane concrete ramp with ample parking for vehicles and trailers. The area is rich in cultural history, with Aboriginal rock art sites accessible from the water, and some guided tours incorporate a visit to these sites along with a lunch stop on a secluded beach. The landscape features heritage sites along the banks, contributing to a scenic and historically significant paddling experience. The water is saltwater, influenced by the tides of the Hawkesbury River. The presence of organized commercial tours suggests it is a popular and established destination for kayaking. The overall character is one of a protected waterway suitable for multi-hour excursions, with a typical route being a paddle north from Bobbin Head to Kierans Creek, covering distances around 15 kilometers.
