I recently had the pleasure of revisiting this walk. National Parks Blue Mountains have been very busy over the last few years upgrading the track; to wide footpaths and boardwalks to several lookouts from Echo Point to along the Three Sisters Walk. This includes down to Spooners Look Out and down to the top of the Golden Stairs now all fully accessible. When I was young this was a moderate hike. Not anymore! This walk is now much easier for those with mobility issues able to access and even wheelchair accessible. It now grants everyone equal access to the spectacular views of the Three Sisters and beyond, looking out towards the majestic Mount Solitary. Suitable for kids and the elderly, it's completely free too! For locals all nearby parking is metered, better to catch a bus down from town (686 from outside the Carrington) for tourists from out of town if you happen to be taking a Trolley Tour or Explorer bus tour there is a stop right at Echo Point (where the Three Sisters Walk begins). There's the Milkbar @ The Lookout Echo Point for a coffee before your walk or lunch afterwards. If an easy walk is not your thing, then you can challenge yourself by continuing on along the Prince Henry Cliff walk for an extended hike. Grab lunch before you go take away from The Milkbar for a picnic lunch. For further information on these walks and extended hikes National Parks has an information shop right at Echo Point too. This is a very populare main tourist attraction so if you don't mind ths crowds go anytime, but to avoid crowds best to go on a weekday during school term at either sunrise or just before sunset for a more peaceful walk.
