Fortress Canyon is a short (800m) canyon along Fortress Creek, North of Leura, in the Blackheath area of Blue Mountains National Park. Only attempt this canyon if you’re fit, experienced and an accomplished user of ropes and other canyoning equipment.
Fortress Canyon is difficult and you should only visit it with a competent guide. Come prepared and allow 6 hours to complete this challenge, which includes an 8km walk to get in and out. The canyon itself has 2 technical sections. You'll need to do 2 abseils, the longest being 10m, as well as downclimbs and jumps. Just beyond the end of this canyon, Fortress Creek plunges off a cliff in a 70m waterfall into Govett Gorge.
Summer is the best time to do Fortress Canyon because you'll need to make long (30m) swims in the chilly waters of Fortress Creek.
To access this canyon from Fortress Ridge car park, walk west along Fortress Ridge Fire Trail and follow the walking track along the ridgetop. After 500m turn right and descend the ridge north east to the creek and to the start of the canyon.

World-class wilderness
The Grose Wilderness is the only declared wilderness area in Blue Mountains National Park. At the heart of the Grose Wilderness is the magnificent Blue Gum Forest. This closed forest of tall blue gum trees is one of the most secluded areas in the Blue Mountains. It also played an important role in the beginnings of the park and conservation movement in NSW. In 1932, the forest was saved from the axe when a group of bushwalkers pooled their money to buy out the lease. Almost 100 years later, intrepid hikers can hike into this natural wonder via Perrys Lookdown or Pierces Pass.
