Bents Basin is a protected nature reserve and state park near Wallacia, New South Wales, Australia in the Sydney metropolitan area. The lake basin, which formed at the efflux of the Nepean River from the Hawkesbury Sandstone (Sydney sandstone) gorge, is a popular swimming hole with a camping area and an education centre used by local school groups. Also featuring a large woodland area and native wildlife, the reserve is the only picnic area along the Nepean River and it is one of the most popular water-based picnic parks in Greater Western Sydney.
