In reply to clipskipper:
I last did Cormorant Buttress in 2019 and there were stakes in place but they were hard to find in the undergrowth.
The traverse from Guillemot into Cormorant Buttress needs a very low tide and flat sea, but the approach from below the Reforn Quarry is easier and should be OK as long as the sea is calm.
If you can find the abseil stakes, you land on a huge block where the route starts and this is well above the sea.
You've only got one day to do the route before the bird ban comes in on March 1st!
