Madeira is definitely a great island, you can find there plenty of points for leasure, great food and madeira wine. And as well nature.

The best how to see the Site is to rent a car (3 days are enough to see the whole island in detail) and drive to Rabacal or Ribeira Frio.

In both locations are very nice Levada tours - which are not difficult for walk and are going through the forests.

Highly recommended island for holiday with a WHS as a bonus ;)
