Gibraltar Rock is a granite outcrop, and is in the Porongurup National Park, which has thirteen total named peaks including Twin Peaks, The Devils Slide, Nancy Peak, Castle Rock, and Elephant Rock. From the rock, which is 2,100 feet (640 metres) high, Albany and the Great Southern Ocean can be seen. Since the 1970s, the Rock, along with some other local peaks, has become a popular venue for rock climbers.
In the early 1990s, the Rock was yielding small amounts of gold to the "dollying" process. It shares characteristics with other terrain in the area which was successfully mined in the late 1800s. The lack of water in the area made more successful mining of the rock difficult in the early part of the twentieth century. As of 1962, the average annual rainfall in the area was roughly 32 inches (810 mm) per year.
Gibraltar Rock has been described as "an enormous hunk of rough granite that provides the longest and most serious slab climbing in WA." The first organised climb by the Climbers Association of Western Australia was done in 1974. One of the faces of the rock is called Dockyard Wall. It was originally graded 17 crux climb. Two climbing bolts were added to this route in 1992. Other routes up the mountain include Second Anniversary Waltz, Crime of Passion, Dinosaur, Apes Den, Illusions of Grandeur,Possum, ApeswayMain Street, Sucked in Ben, Moorish Steps, Europa Point, Rooster Carnage, Joint Venture, and Zeppelin.
