Popran Creek is a freshwater creek located in Glenworth Valley, New South Wales, roughly 20 minutes from both Gosford and Hornsby. The creek flows through bushland before widening and eventually connecting with the Hawkesbury River. The waterway is calm and sheltered, with no waves or significant current, making it accessible to paddlers of all experience levels including complete beginners.

A guided eco-kayaking tour operates out of Glenworth Valley Wilderness Adventures, covering approximately 5 kilometres return over 2.5 hours at a relaxed pace. Independent paddlers also use the creek, with trips extending to Popran and Kelly's Creek and covering around 15 kilometres when tidal and wind conditions are favourable in both directions. The tidal influence from the Hawkesbury can assist paddling in both directions depending on timing.

The creek passes through native bushland and supports a notable variety of birdlife. Observed species include sea eagles, cormorants, ducks, ibis, and white-faced herons. Casuarinas line portions of the banks. The guided tours also highlight historical artefacts along the route, though specific details of these features are not elaborated.

A rest stop at a location called Neverfail is a feature of longer paddling trips, where groups have taken morning tea. The Glenworth Valley operation provides guided tours with equipment included, and the property is set up to accommodate families, school groups, and corporate groups. Participants on guided tours are required to sign a risk warning and waiver of liability contract before launching.

The creek is suitable for paddling year-round, with a late-winter paddle in August described as offering excellent conditions. The combination of tidal assistance and prevailing winds can make longer trips on the lower reaches more manageable when planned around tidal cycles.
