Ngilgi Cave is the major inland sight at Yallingup, a limestone cave system with lit chambers, stalactites, stalagmites, and interpretation of the Wardandi story connected with the place. It was formerly known as Yallingup Cave, and is one of the easiest show caves to add to a South West coast day.
Allow about ninety minutes if you want to take it slowly. The cave is a useful change of pace when wind or swell makes the beaches less inviting.
