Walyunga National Park, Nature reserve in City of Swan, Australia

Walyunga National Park is an 18-square-kilometre national park 35 km northeast of Perth, where the Avon River cuts a steep valley through the Darling Range. Grey granite outcrops and darker dolerite patches rise above the river, and laterite caps the hilltops. In summer the river forms a chain of pools; in winter it becomes a rushing torrent with rapids.

Walyunga holds one of the largest Aboriginal settlements in the Perth region, inhabited until the late 18th century. Archaeological finds show the area was occupied at least 6,000 years ago. The name may derive from the local Nyoongar group, with Wal-yunga possibly meaning 'northern Nyoongar', though 'happy place' is also proposed.

The park has multiple marked walking trails of varying lengths and picnic areas with barbecue facilities available. Visitors should wear sturdy shoes and bring plenty of water, as the trails traverse hilly terrain and can be uneven.

The annual Avon Descent, a multi-day river race, takes place on the Swan-Avon River flowing through the park, attracting paddlers and rowers from across the region. This event has made the location well-known among water sports enthusiasts.
