12-13 May 2007: Completed the strenuous overnight walk in the Northern Grampians along the Mount Difficult Range. Started the walk from Troopers Creek Camping Ground, ascended the steep track to Mt Difficult campsite via Tilwinda Falls. Dropped packs near the campground and dashed to Briggs Bluff. Made it back to the campground just before it got dark fully exhausted. Climbed to the summit of Mt Difficult the following day and retraced our steps back to the car.
