To the south of Cairns is the highest free standing natural pyramid in the world. You could be forgiven for thinking it is a tree covered man-made pyramid – the shape is almost perfect. But no, this is a natural phenomenon that is one of the most distinctive landmarks for the small sugar-farming town of Gordonvale.
Walsh's Pyramid is used for hiking. The mountain is 922 metres tall, and quite steep so you need to be fit and healthy to make the climb.
An annual footrace is held on the third Saturday in August, to its summit. The "Pyramid race" starts at the nearby town of Gordonvale and attracts hundreds of competitors aiming to win the $1000 prize money.
For experienced hikers, the ascent and descent can take 4 to 6 hours. The vegetation on the mountain is fairly dense, however many rocks are open and exposed which make the surface very slippery after rain.
