The most visited and photographed attractions in the Blue Mountains are the rock formations known as the Three Sisters. For the best vantage point, head to Echo Point Road, across from the Blue Mountains Tourism office. Or try Evans Lookout, Govetts Leap, and Hargreaves Lookout, all at Blackheath -- none of which are on the Blue Mountains Explorer Bus or Trolley Tours route.
The Scenic Railway, the world's steepest, is a must-do in the Blue Mountains; follow the road signs to Scenic World. It consists of a carriage on rails that is lowered 415m (1,361 ft.) into the Jamison Valley at a maximum incline of 52 degrees. It's very steep and quite a thrill. Originally the rail line was used to transport coal and shale from the mines below in the 1880s. The trip takes only a few minutes; at the bottom are some excellent walks through forests of ancient tree ferns. A boardwalk makes it suitable for those who like their bushwalking easy. Another popular attraction is the Skyway, a cable car that travels 300m (984 ft.) above the Jamison Valley. The round trip takes 6 minutes. The Scenic Railway and the Skyway combination (tel. 02/4780 0200; www.scenicworld.com.au) costs A$21 round trip for adults, A$10 for children, and A$52 for families. They operate from 9am to 5pm daily (last trip at 4:50pm) and depart from the ticket office at 1 Violet St., Katoomba. I'd advise taking the Scenic Railway down, going for a walk, and taking the cable car back up.
Canyons, waterfalls, underground rivers -- the Blue Mountains have them all, and before you experience them in person you can catch them on the (giant) screen at The Edge Cinema, 225-237 Great Western Hwy., Katoomba (tel. 02/4782 8900). The special effects shown on this 18m- (59-ft.) high, 24m- (79-ft.) wide screen make you feel like you're part of the action. At the time of writing, the 38-minute film The Edge was being shown every day at 10:20, 11:05am, 12:10, 1:30, 2:15, and 5:30pm. Tickets cost A$15 for adults and A$10 for children. The cinema is a 5- to 10-minute walk from the train station. Recently released movies play on part of the giant screen in the evening.
To get back to Sydney, I highly recommend taking the Bells Line of Road through Bilpin. This route takes up to 3 hours, but you can stop off at the wonderful Mount Tomah Botanic Gardens. (You can't miss the large sign on your right about 10 min. before you get to Bilpin.) An adjunct of the Royal Botanic Gardens in Sydney, Mount Tomah is dedicated to cold-climate plants. Allow around 2 hours for a stop here.
Seeing the Blue Mountains from the Back of a Harley
A thrilling way to see the Blue Mountains is on the back of a chauffeur-driven Harley-Davidson motorcycle. Wild Ride Australia (tel. 1300/783 338, or 0410/418 740 mobile; www.wildride.com.au) will pick you up from your hotel in the Blue Mountains and take you on a 1-hour exhilarating ride to see some of the sights around Katoomba. Rides cost A$130.
