Are they always large groups of cyclists on it in good weather?

Thanks Mike of course I cannot answer this we ought to ask one of the
local riders. What I can say is that I was there on a friday beginning
of October ( not high season although weather was still great ) and I
was really impressed by the amount of people riding it. At the top
there is a large parking lot with shops and it was jam packed of
riders! It is a great climb and suggest all serious bikers going
around that area to puff all the way up as it is really worth it.
