Last weekend I climbed Barn Bluff as a day trip from Ronny Creek.
Had amazing views of sunrise on the Fagus as I passed Crater Lake, and lovely views again around Marion's Lookout. From that point south I had limited visibility all the way to the summit of BB which was disappointing. However, on the return trip a lot of cloud/fog cleared and there were fantastic views out to the east.
Instead of returning via the OLT, I decided to go via Lake Rodway, mainly because the eastern views were good, but the west was still foggy. The latter part of the Lake Rodway track (heading North) provided spectacular views of the eastern side of Cradle Mountain, but apart from that I found the state of the track to be frustrating and I certainly won't be using it again.
It was wonderfully clear from the area of the ranger hut, all the way back to Dove Lake where I caught the shuttle out.
It only took 3 hours and 15 minutes to the summit of BB from Ronny Creek, and the whole walk was about 7 hours in total, covering 25km.
