The south-western part of Sicily follows along the coast either side of Agrigento, and heads inland (and uphill) onto the high plateau that includes Piazza Armerina.
The highlight at Agrigento is the extraordinary Valley of the Temples - although you will probably find that the many attractive beaches of the area occupy more of your time!
The mosaics at the Casale Imperial Palace in Piazza Armerina are an incredible sight, and cover a very extensive floor area in what was once one of the grandest villas in Sicily.
Beaches and coast
The south-west coast includes some of the best beaches along the Sicily coast - and a bit too much development in places. Try the coast around Realmonte for some of the highlights.
The beaches near Gela are among the best - many of the beaches tend to be quieter in this part of Sicily than in the more visited regions.
For some of the most impressive coastline you might continue towards Africa with a visit to the Pelagie Islands - especially well known to deep-sea diving enthusiasts because of the clear seas and the wide range of creatures that can be seen in the sea. The main island is Lampedusa, the other two are Linosa and Lampione.
