There are many who argue that this is still the case.

If you're heading out on the Lindeman Pass be warned: many have tried, and plenty have got lost along the way (so many that the Katoomba Police Station offer Personal satellite tracking devices for those heading out on the trail). While the Lindeman Trail follows a defined route, it is not always clearly marked as it winds its way through the forests. What's more, it's not easy. Exposed in places, slippery in others, the Lindeman Pass requires a good technical bushwalking skills and an ability to navigate tough terrain. Download maps before you go!

Still interested? If so, be prepared for an epic adventure that boasts sensational views and challenges aplenty. Starting out from Katoomba, follow the Federal Pass down to Linda Falls, then keep on going to Lindeman Pass. From that point, there is only one (official) track as you skirt the lifts. Stay alert and keep navigating as the trail can be hard to follow at times.

Before setting out on a trail like this be sure to check the NPNSW website. Bush fires and heavy rains have affected trail conditions throughout the Blue Mountains. If you are not confident on technical trails, do not do this hike.
