Jewel Cave Tour Review

Tours leave every half hour from 9.30 am to 3.30 pm and usually require at least two visitors. The hour-long tours are family-friendly, although it might be too long for very young children’s attention span.

The Jewel Cave centre has a café, gift shop, toilets, and interpretive area detailing the cave’s history, development, and conservation. Make sure to make use of the restrooms before your tour starts.

We met our friendly guide, Murray, by the glass doors and headed out for a quick safety briefing. Throughout the tour, he was informative and knowledgeable and explained all the important formations as we made our way around the three massive chambers.

As you enter the first chamber, the beauty strikes you immediately with the cave lit up in a golden glow, highlighting the intricate decorations that adorn the cave ceiling. You make your way along a wooden boardwalk and stairs to the first platform, where your guide explains the history of Jewel Cave. If you look up, you can see the Karri trees’ tap roots trying to find moisture in the cave and the natural entrance hole formed from a decayed tree.

Some of the amazing geological formations you will see as you pass through the cave are:

  • the longest straw stalactite in an Australian show cave (5.43 metres long)
  • the frozen waterfall and organ pipes (beautiful examples of flowstone)
  • cave coral (showcased with lighting effects)
  • fossils
  • helictites
  • stalagmites
  • ribbon drapery (cave bacon)
  • pendulites

Your guide will explain what they are and how they formed.

Bones of the now extinct Tasmanian tiger (Thylacinus cynocephalus), which fell into the cave before the cave was discovered, can be seen in the centre. The skeleton you can see in the Jewel Casket (the lower part of the cave) is a Brush-tailed possum, dated to be 400-500 years old. At this point, look up and see how far down you are – almost 30m deep, meaning Leeuwin Lighthouse can almost fit into this cave!

Towards the end of the tour, all lights are turned off (including phones, etc.) so you get to experience a complete blackout and experience what it was like for the first explorers of the cave.

Despite having 500 stairs (250 down and 250 up), the platforms along the way stagger the descent and ascent. The cave has more CO2 than the air outside, which can cause you to feel breathless climbing the stairs on the way back up. Take your time and rest on the platforms if you feel out of breath.

The tour takes a loop around the three chambers, so you get to see different formations throughout the whole tour. The boardwalks make it easy to navigate, but parts on the return are narrow. You may need to duck your head a few times and squeeze through narrow parts, but it’s all pretty easy.

At no point in the tour did we feel claustrophobic. On the contrary, the caves were huge, with plenty of room to move around.

As mentioned previously, this has been my favourite cave to date and well worth the cost of the tour.

Jewel Cave History

Jewel Cave is in an area known as the Leeuwin-Naturaliste Ridge, formed from coastal sand dunes when westerly winds along the coast blew beach sand, shells, and corals into huge sand dunes during the last million years. The sand cemented together to form limestone (Aeolian calcarenite) by the action of rainwater.

Data suggests that the limestone could be older than Middle Pleistocene (approximately 1 million years ago). A cave decoration from Jewel Cave, made from calcite, a crystalline form of calcium carbonate, was dated at 466,000 years old.

A “wind hole” was known back in the early 1900s but wasn’t rediscovered until 1957, when Cliff Spackman and others found it. Cliff was lowered into the cave and descended 12m through a solution pipe into the chamber. Cliff, Lloyd Robinson, and Lex Bastian continued the exploration in February 1958, where they discovered more than 2 km of cave passages.

Jewel Cave opened to the public on the 26th December 1959 and was named after the Jewel Casket, a small chamber in the lower section of the cave.
