We drove up from Casula NSW and set out from Evans lookout carpark (Evans Lookout Road) near Blackheath in the Blue Mountains. There are waterfalls, creeks and spectacular views/scenery along the track. The track is easy enough to navigate and is sign posted. You will need proper footwear, hat, sunscreen etc There are a lot of stairs which can be challenging and it does get quite hot, so be sure to take plenty of water and maybe a snack. Well worth the effort :) We did the walk in 3 hours although it is suggested that it will take 3.5 - 4 hours.

Arresting sandstone walls, ever-present waterfalls and abundant native plants line the awesome Grand Canyon track near Blackheath in the Blue Mountains. The historic loop track takes you into the heart of this World Heritage-listed landscape. It's an intimate and adventurous track which walkers have trodden since 1907.
Setting out from Evans lookout, the well-shaded track meanders through luscious native vegetation of ferns and golden wattles, and remains close to Greaves Creek, all of which combine to make this a particularly good walk for the summer months. Shorten the loop by leaving a second car at the Evans Lookout Road entrance or spend the day and stop for lunch at the nearby picnic area before returning to the lookout.
Although there are loads of semi-ledges which make up this challenging walk, you don’t need specialist hiking or abseiling equipment, so comfortable walking shoes are all you’ll need to get out there and explore. Still feeling energetic? Try the nearby Cliff Top walking track.
Check the weather before you set out as the creek can flood after heavy rain
