We arrive at Wollemi National Park, driving through a series of rock tunnels which seemingly transport us into another world. Our guide explains the route ahead, before we set out through a landscape of tall eucalypt forest with Blue Mountains Ash, spectacular pagoda rock formations, vibrant ferns, canyons and streams.
We arrive at the entrance to a cave like tunnel, from here we walk under the mountain range, taking a fascinating short cut to the Wolgan Valley and the beautiful Gardens of Stone National Park. We descend into the darkness with our trusty torch in hand, stopping halfway to turn off our torches and be amazed by the thousands of Glow Worms which transform the tunnel into a starry night. Though natural looking from its exterior appearance, this tunnel is actually a disused railway line, which once descended into the Newnes valley, transporting oil shale.
