Essaouira is a lovely little place and an easy side trip from busy Marrakech. Although it's the medina that is the main focus of the WHS, there are more things to when you're there. In the warmer months, the beach is a great place. My favourite area was the port, full of blue boats and blue nets - it's really picturesque.

There are some nice riads for accommodation in the medina and some interesting little side streets once you get away from the main boulevard. Well worth the trip, even if it wasn't a WHS.
