Magnetic Island

More than half of Magnetic Island's 52 square km (20 square mi) is national parkland, laced with miles of walking trails and rising to a height of 1,640 feet on Mt. Cook. The terrain is punctuated with huge granite boulders and softened by tall hoop pines, eucalyptus forest, and rain-forest gullies. A haven for wildlife, the island shelters rock wallabies, echidnas, frogs, fruit bats, nonvenomous green tree snakes, and Northern Australia's largest population of wild koalas. Its beaches, mangroves, sea-grass beds, and fringing reefs support turtle nesting, fish hatching, and a significant dugong population. You can escape to 23 beaches and dive nine offshore shipwrecks.
