Tours of the Mountain Maid mine and surrounding heritage gold mining site along the Hidden Treasure Track (only accessible via a guided tour) will start back up in 2021.
Hidden Treasure track is an easy walk through dry rainforest following Copeland Creek beneath a canopy of grey myrtle, shatterwood, yellow tulip and other dry rainforest species. This hike also takes you past remnants of the area’s mining history. Look out for adits, which are tunnelled entrances to underground mines. See the boiler from Criterion stamper battery, which used to provide the power to crush ore from the nearby mines.
Hidden Treasure gold reef was discovered in 1877. Despite the name, the treasure did not really stay hidden for long, and this mine became the area’s second most productive, yielding 269kg of gold after its construction. Now that all those miners have left, microbats have moved in and travel back and forth from the cave through the open mesh grill at the mine entrance, generally scavenging for insects.
