The area was inhabited and was a noted hunting site for thousands of years by Indigenous Australians prior to the arrival of Europeans.

The word Yanchep is derived from Yandjip or Yanget which is the aboriginal name for the local bulrush reed found fringing the lakes in the area.

[2] The first European visitor arrived in 1834 when John Butler, a farmer, came in search of his lost cattle and noted the presence of the lakes, wetlands and plentiful game.

Trees such as banksias, paperbark, tuart, marri, she-oak and stunted jarrah are found in the woodland areas.

Wildflowers including parrot bush, yanchep rose, catspaw and kangaroo paw are also found.

[5] The park provides habitat for several species of native mammal, including the quenda, western grey kangaroo and black-glove wallaby.

[6] Yanchep National Park is open year-round and offers a variety of nature-based activities for visitors.

[12] The Yanchep Inn is a fully licensed restaurant open 7 days a week and serves breakfast, lunch and dinner.

[21] In 1932, it was developed into an underground function centre where the cave's two main chambers were converted into a supper room and a ballroom.
