We have stayed in this area, it is call Jardin d' Orient as Carol mentioned.
When we stayed there there was an electric gate to gain access. I don't remember how far around the fence went.
The views are stunning from up there.
I thought we would be able to walk to the beach but it is a pretty good hike especially if you're carrying anything. Of course, then there is the walk back uphill.
The hill is steep and we needed a 4 wheel drive car. Our friends didn't have one and the ride up in their car was a bit of a white knuckle ride. But that may depend on which villa you're looking at renting.
