The Minyon Falls is a plunge waterfall on the Repentance Creek in the Northern Rivers region of New South Wales, Australia. The waterfall descends more than 100 metres (330 ft) over the huge rhyolite cliffs which were once part of the Tweed Volcano. The water flow eroded the underlying basalt away to create the waterfall.
The waterfall is a popular visitor attraction and is located within easy reach of the nearby town of Byron Bay in the Nightcap National Park, which was added to the Gondwana Rainforests of Australia World Heritage Site in 1986.
The National Parks and Wildlife Service manages the area as part of the Nightcap National Park, and provides facilities for visitors, including a 50m boardwalk to the lookout which is wheelchair accessible, several picnic tables and barbecue facilities at the top of the falls. The National Parks and Wildlife Service do not permit camping in the Minyon Falls area, but a camping ground is provided 2 kilometres (1.2 mi) west of the falls at Rummery Park. Visitors are able to explore the bottom of the falls and the sub-tropical rainforest along designated walking trails, all of which involve steep hills, with some scrambling over wet rocks at the base of the falls. One trail follows a route 4.5 kilometres (2.8 mi) from the top of the falls, across the ridge, near Quandong Falls, down into the valley to the bottom of the Minyon falls, it continues 2.5 kilometres (1.6 mi) to Minyon Grass, then joins the road for 1.2 kilometres (0.75 mi) back to the falls car park to form a loop. A shorter, 2.5 kilometres (1.6 mi) track runs from Minyon Grass to the bottom of the falls. Another walking trail in the area is the Boggy Creek Walk from the Rummery Park Campground to the top of the Falls (45 minutes each way).
The top of the falls is surrounded by wet sclerophyll forest with some very tall blackbutt, tallowwood and flooded gum trees. Visitors to the falls regularly observe wildlife such as lace monitor (goanna), kookaburra, satin bowerbird, noisy pitta, eastern yellow robin, peregrine falcon, bobuck possum, northern and long-nosed bandicoot, tawny frogmouth, stony creek frog, red-eyed green tree frog, red-necked pademelon and carpet python.
