The main ticket office for Lake , Mammoth and Jewel Caves , CaveWorks also has excellent displays about caves, cave conservation and local fossil discoveries. There's also an authentic model cave and a 'cave crawl' experience. Behind the centre is Lake Cave, the prettiest of them all, where limestone formations are reflected in an underground stream. The vegetated entrance to this cave is spectacular and includes a karri tree with a girth of 7m.
Lake Cave is the deepest of all the caves open to the public. There are more than 300 steps down to the entrance (a 62m drop).
CaveWorks is 20km south of Margaret River, off Caves Rd. Single cave tickets include entry to CaveWorks. The Grand Tour Pass (adult/child $55/24), covering CaveWorks and all three caves, is valid for seven days, while the Ultimate Pass (adult/child $70/30) also includes Cape Leeuwin lighthouse.
