In reply to lambretta man:
Shaftoe can be a bit confusing....
For a first visit you're better off sticking to the better known areas.
You can do a bit of a circuit by heading straight to the Cob/Main Wall area, move down to the neb and turtle rock, then head down to the font boulder and return via the ravine and/or lost arrowhead boulders.
Plenty to go at there in the 5s and 6s
Don't think I'll be around on Saturday but have fun, it's a quality venue (if you don't get lost)
