Once a year, Queensland’s oldest tourist attractions are transformed by a well-positioned beam of sunlight. Here’s how to see it.
At any time of year, Queensland’s Capricorn Caves are a wonder. Sitting 23 kilometres north of Rockhampton (and just off the Pacific Coast Way), the limestone forming this cave system dates back approximately 400 million years. The caves themselves were carved by underground water and acidic rain. The result is some pretty spectacular formations.
But, every year around the Summer Solstice (which always happens during December and January), there’s one more magical reason to descend into the depths. The alignment of the sun over the Tropic of Capricorn is such that a bright beam shines right into the darkness of a 14-metre deep shaft leading into Belfry Cave.
This unbroken beam of light, pretty impressive in its own right, can then be refracted by items in the cave. Say like, a disco ball. The result? Something of an underground cave rave, made from the sun but lighting up the depths of the earth. Add a little colour to that refraction, like the colour of your clothes, and the result could put your favourite disco to shame.
Capricorn Caves make the most of this natural phenomenon with its yearly Echoes of Sunlight tour, running every year in December and into January. Led by experienced local guides, the tour showcases the largest and most spectacular caves, sharing history along the way, from ancient geological formations to early explorers, local wildlife, and even special cave acoustics.
What else to see at Capricorn Caves
Besides this light show, Capricorn Caves boast some other spectacular sights: an abundance of native wildlife and endangered species that call the caves and surrounding area home, fossils from ancient marine life and other creatures that once inhabited the area in The Colosseum cave, the breathtaking natural acoustics (you can even hear a tiny whisper from one side to the other) and striking formations found in Cathedral Cave. In fact, the latter is so spectacular it’s known as the crown jewel of Capricorn Caves and is a popular venue for weddings and concerts.
Extend your stay in one of the fully self-contained cabins or caravan sites, and enjoy coffee and classic cafe meals at the on-site, licensed cafe.
The details
Tours start on December 13, 2026, so keep an eye on the website for bookings to open. The Summer Solstice is a natural phenomenon; if the weather is rainy or overcast, there’s no guarantee of viewing the lightshow. Regardless, you’ll be able to enjoy a very informative tour and explore the other wonders of this incredible cave system.
