Greater Beedelup National Park, Nature reserve in Shire of Nannup, Australia

Greater Beedelup National Park is a nature reserve in the Shire of Nannup in southwestern Australia. The park contains extensive stands of karri trees that reach heights of 90 meters and is crossed by Beedelup Brook, which features a waterfall.

The park was gazetted in 1910 and declared an A Class Reserve in 1915. The Pemberton National Parks Board has managed it since 1957. Controlled burns are carried out, and some areas once State Forest were clear-felled and have since regenerated.

The name comes from Beedelup Brook, recorded in 1875. It is thought to derive from the Noongar word Beejalup, meaning place of rest or place of sleep, used by the Noongar, the traditional owners of this area.

A signed walking trail loops around Beedelup Falls, with a rest area, picnic area and toilets on site. Camping is not permitted and an admission fee applies. The falls flow fully in winter and spring, while Beedelup Brook does not carry water all year.

A suspension bridge built in 1995 crosses Beedelup Brook and offers direct views of the waterfall below. This structure is a highlight of visiting the area and provides an up-close perspective on the cascading water.
