There are several caves in the Margaret River and this is the biggest and in my opinion the best, many spectacular stalagmite and stalactite formations with some lit with coloured lights for effect, you can by a pass that gets you entry to all of the caves in the area or just get a pass to see the individual caves with ticket prices quite reasonable, there is a Cafe for food and drinks but I would recommend taking a bottle of water with you and definitley a camera, the cave has a lot of steps but you can view at your own pace this cave is located around 10km south of Margaret River on Caves Road, in my opinion you don't need to get a cave multipass as this one has it all, if you prefer less steps then try the nearby Jewel Cave.
