Purling Brook Falls, Springbrook: top, base and the gorge

Purling Brook Falls, Springbrook's showpiece on the plateau, leaves the cliff edge as a single column and falls into a gorge full of palms, tree ferns and stream lilies. The park listing on Destination Gold Coast gives the drop as 100m.¹ The same tourism body's waterfall guide describes it as a horsetail fall plunging 300 feet into a gorge, and places it in the World Heritage listed Gondwana Rainforest of the park.^8,9 Both figures describe the same tall drop.

Destination Gold Coast goes further and calls it the highest and the best waterfall in the area.¹⁰ Even without the ranking, the setting earns the trip. The cliff is ringed by eucalypts on top, with rainforest crowding the bottom of the gorge, so you walk from dry, open bush into dripping green in the space of a few hundred steps. The change in air temperature as you go down is part of the experience.

The falls are part of a much wider story. The hinterland behind the Gold Coast holds more than 500 waterfalls, by the tourism body's count.¹¹ The Australian Government's World Heritage notes describe high waterfalls crashing into steep gorges as living examples of erosion, the slow process still shaping these ranges.¹² Purling Brook is that process in action: water steadily cutting back into the rock of an old volcanic plateau.

The plunge pool under the falls is off limits. Swimming is prohibited at the base of Purling Brook Falls.⁶ Destination Gold Coast names it beside the Natural Bridge and Curtis Falls as places closed to swimmers, to shield a sensitive ecosystem that is home to glow worms, microbats and platypus.¹⁸ Enjoy the spray from the track instead; on a warm day it does the job of a swim anyway.

There is also a safety reason to stay on the formed path. The plunge pool sits right under a high cliff, in the full force of the falling water. Treat the barriers and signs as final. The tourism body's general advice for the park is to keep well back from cliff edges and watch your footing on wet rock near falls, and that applies with full force here.¹⁹ Keep children by the hand on the wet sections near the pool.

The good news for swimmers is a short walk away. The Warringa Pool track leads downstream from the base of the falls, and the waterfall guide suggests it for a dip on a hot day.⁶ The next section explains how far it adds to the walk and what you find there. Throw bathers and a light towel in your pack if the pool is on your list: they weigh little, and it is a long climb back to the car to fetch them.

The falls change with the seasons. Rainfall at the Bureau's gauge on Springbrook Road averages 316.2 mm in March against 67.1 mm in September.¹⁶ After a wet stretch the water fans out into a broad, roaring curtain; in a dry spring it can shrink to a thin thread, still beautiful, but very different. The hiking guide says the view from the base is at its most dramatic after heavy rain.¹³

Rain also closes the walk. After significant rainfall, parts of the Purling Brook track may be shut for public safety.⁷ Queensland's park service tells walkers to look up the park alerts before setting out, and to check weather and roads too.⁴⁰ On a wet day the view from the top may be all you get, and with the falls in full flow it can still be the highlight of the trip. Bring a rain jacket either way; weather on the plateau turns quickly.

Cloud is the other factor. The plateau often vanishes into cloud while the coastal strip below stays sunny, so pick a clear day with no smoke haze for the widest view.⁴¹ A morning visit after a night of rain, with the cloud lifting, can give you full falls and a clear valley at once. If the plateau is in cloud when you arrive, the gorge walk is still worth doing: you are below the cloud and close to the water.
