Almalfi coast of Italy

I've never been to Italy - never thought of it until I turned on the
TV
last night and saw this part of it on PBS - I suspect it was an "Over
Italy" show like "Above Germany") it was an aerial tour of Italy - a
series of short clips looking down as they flew along. They were
showing a coastal route like Big Sur and all I know is that the text
with the clip read " near Sapri" . It may have been 100 miles away ?
I went searching online for info / video and can only find things like
this comment from a poster at Rick Steve's website:

"The entire coast line from Sapri south for the next 100 miles is
simply stunning. The water is emerald green and the coast is dotted
with tiny coves and broad sand beaches. It reminded me of the Big Sur
coast of California, only more isolated."

For those that have been there ... about that road ... it looks pretty
narrow and no guard rails which might take some of the fun out of it
if someone coming at you isn't paying attention. Is that right ?
What's the climate like near there - is it cold in February or
tropical ?

What is this road ? WHERE IS THIS ? How do I get there ? Where to fly
into ? What's at each end of "that road" ?
