There are many gorgeous beaches all along the Amalfi Coast that aren't touristy. This is because you have to figure out how to get to them! Look for staircases along the sides of the road. We didn't have much time to explore, but the locals were raving about these hidden sanctuaries.
There are many sights to see while travelling down the Amalfi Coast and probably lots more than those that I saw. We were dependent upon the bus driver to stop at good spots (another reason why I will drive next time). This was one of those spots.
20 minutes walk from Anacapri and you're near the coast. Off the beaten track and out of this world. Some very nice gardens and villas round there.
Easily accessed by SITA bus from Sorrento (about 1 hour). Very relaxing, not many tourists, great place to chill.
