The Fortress is a 6.5km, grade 4 return hike located in the Grampians National Park, Victoria. The hike should take around 3 hrs to complete.
Hike overview
For many years the Fortress was regarded as a mythical destination, lost as it is deep in a wild mountain range in one of the most remote corners of the Grampians. Its massive grey buttress and sweeping cliffs rise high above the treetops to form a singular tower that dominates all other surrounding peaks.
This scenic hike climbs from Harrops Track up to below the fortress and visits two popular camping caves along the way. It is a fairly strenuous hike but there are plenty of resting points along the way.
Should you have a head for heights and don't mind a bit of rock scrambling it is possible to climb to the top of the Fortress. It is a reasonably challenging climb for experienced hikers only. Do not consider the climb in wet or inclement weather.
