Khappinghat Creek is a coastal estuary located near Diamond Beach and the Saltwater National Park, approximately ten minutes from the towns of Taree and Forster. The waterway offers a flatwater kayaking and canoeing experience in a tranquil, estuary setting. The surrounding landscape features rainforest, mangroves, and salt flats, contributing to a peaceful atmosphere. The creek is situated at the northern end of the six-kilometre-long Diamond Beach, which is noted for surfing, indicating that ocean access may involve navigating a surf zone. The area is part of a broader study of southern estuaries, which includes systems like Wallis Lake and Myall Lakes. The creek's proximity to Diamond Beach and Saltwater Point suggests potential coastal access points. Paddlers should be aware of potential boat traffic, as a boat ramp is located in the broader council area. The estuarine nature means tidal currents will be a primary factor for trip planning, requiring coordination with tide stages to paddle with or against the flow. Water quality assessments have found no evidence of broadscale increases in acidity from local sources, though the waters are known to contain tannins, which can stain the water a dark colour but are a natural feature. The area is known for dolphin sightings off the adjacent beach. Facilities in the nearby Hallidays Point village include a shopping precinct, clubs, and restaurants.
