Thunderegg Fossicking

Thunderegg Fossicking at Tamborine Mountain provides an outdoor experience where visitors search for agate-filled rocks within an ancient dried-up lake bed. The site sits on the world’s largest deposit of thundereggs, formed by volcanic activity millions of years ago. Participants receive a bucket and pick to locate specimens, which are then taken to the rock shop for identification. Professionals on-site offer cutting and polishing services to reveal the internal crystal patterns of the found stones. The attraction is located within the Thunderbird Park precinct, providing a structured environment for geology education and outdoor recreation. It is situated a short drive from the Tamborine Rainforest Skywalk, making it a central point for visitors exploring the hinterland. Facilities include equipment hire and a retail outlet featuring various minerals and gemstones. The activity operates daily and caters to both individual tourists and large organised groups seeking a hands-on earth science activity.
