3 Best Sights in The Blue Mountains, New South Wales

Overlooking the densely forested Jamison Valley and three soaring sandstone pillars, this lofty promontory has the best views around Katoomba. The formations—called the Three Sisters—take their name from an Aboriginal legend that relates how a trio of siblings was turned to stone by their witch-doctor father to save them from the clutches of a mythical monster. The area was once a seabed that rose over a long period and subsequently eroded, leaving behind tall formations of sedimentary rock. From Echo Point—where the visitor center is located—you can clearly see the horizontal sandstone bedding in the landscape. There is a wide viewing area as well as the start of walks that take you closer to the Sisters. At night the Sisters are illuminated by floodlights. There are cafés and a visitor information center near the site.

Stalactites, stalagmites, columns, and lacelike rock on multiple levels fill the fascinating Jenolan Caves, a labyrinth of vast limestone caverns sculpted by underground rivers. There are as many as 320 caves in the Jenolan area. Two caves (Nettles Cave and Devil's Coachhouse) near the surface can be explored on your own, but a guide is required to reach the most intriguing formations. Standard tours lead through the most popular caves—many say that Orient Cave is the most spectacular—while the more rigorous adventure tours last up to seven hours. The one- to two-hour walks depart every 15 to 30 minutes, on weekends less frequently. Prices start at A$55 for a standard tour. Concerts and murder mystery nights are also held in this spooky environment. Cave House, on the same site, is a nostalgic retreat and has been providing lodging since 1887. To get here, follow the Great Western Highway north out of Mount Victoria, then after Hartley, turn southwest toward Hampton.

Thrill-seekers can choose their own adventure on the Scenic Railway, whose trains descend 1,000 feet down the mountainside—the seats allow passengers to adjust the incline angle from 52 to a hair-raising 64 degrees. The railway is one of three attractions at Scenic World, which has carried more than 25 million passengers to the valley floor since it opened in 1945. Once at the base, visitors can hike on easy trails through the rain forest or make the 20-minute hike to Cableway, a huge cable car that whisks passengers back up the mountain. You can also hike back up, but it's a steep, strenuous climb. The third attraction is Scenic Skyway, a glass-enclosed and -floored cabin that travels from one cliff to another, some 920 feet above the ravines below. The A$49.50 day pass provides unlimited rides on all three attractions.
