Recently did Rumpf Saddle to the Viking.
Found Mt Speculation well signed (and what great hiking and climbing). Signage good from Catherine Saddle right along the trail over Mt Despair. From the base off Mt Despair, very trail markers at first, then as you proceed towards the Viking weaving in and out up and down a rocky way markers are more prevalent. thank god!
If you get hike around this spot and find a Garmin GPS let me know and collect a reward.
On the approach to the Viking Saddle the trail marking is excellent, right up to the notorious rock chimney BYO rope.
After getting to Viking your are on your own no markers and very difficult track locating. It caused me to become exhausted and a rescue.
Good hiking
