One of Australia’s own World Heritage Sites, the Greater Blue Mountains area features a dynamic landscape of vast gorges, sandstone plateaus, fertile rivers and lakes, and huge cliffs diving headfirst into unexplored valleys. The Blue Mountains are also home to rare and endangered wildlife, many of which rely on the extraordinary diversity of the area’s eucalypt species. These same trees are also responsible for the region’s name, as the landscape’s blueish hue results from the oils released by eucalypts in warm weather. Just 60–90 minutes northwest of Sydney, the Greater Blue Mountains Area is a popular travel spot among outdoor enthusiasts of all ages. Hiking trails, abseiling, and magnificent lookouts are just a few of the things drawing more visitors to the Blue Mountains every year.
