The Stirling Range seems to generate it's own micro-climate and foggy mornings are not uncommon.
The fog lifts quickly as the sun rises but do take care on the roads and also on the mountain trails.
Cloud can also come in quickly to make the mountain trails a little tricky to see.
Take your time and take care!
The path on Bluff Knoll is relatively easy to follow particularly the first part of the ascent which are stepped rocks.
Nearing the top there is are some small side tracks to beware of as you may lose your way slightly.
More importantly, stay well away from any edges and ledges!
They could be slippery and will most likely lead to a cliff and a long, flying freefall.
There is no danger music to warn you!!!
