Greece is made of three major land groups, the mainland, the Peloponnese Peninsula and the islands offshore. The land is comprised of approximately 80% mountains and hills, making it one of the most mountainous countries in all of Europe. The mountainous area known as the Pindus region is an extension of the Alps.  Many people will know the popular islands of Greece (Mykonos, Santorini), but the heart and soul of the Greek people will be found in small villages of the mainland.
