Natural Bridge, Springbrook National Park

A rock arch over Cave Creek, formed when a waterfall wore a hole through the roof of the cave beneath it, so that the creek now pours through the hole into the cave. An easy 1 km circuit walk through subtropical rainforest leads down to it.

At night, the cave roof glows with thousands of glow worms. Go after dark with a red-filtered torch, keep your light off the glow worms and keep quiet, or join a guided night tour. Swimming in the creek and cave is not allowed, to protect endangered frogs.

The area is the land of the Kombumerri people. Getting there: from the M1 take exit 69 at Nerang and follow the Nerang–Murwillumbah Road for about 35 km, past the Hinze Dam. Or take the scenic route via the Springbrook plateau. The road is winding, so drive with care.
