Crete is the largest and most populous island; Euboea, separated from the mainland by the 60m-wide Euripus Strait, is the second largest, followed by Rhodes and Le**os. The Greek islands are traditionally grouped into the following clusters: The Argo-Saronic Islands in the Saronic gulf near Athens, the Cyclades, a large but dense collection occupying the central part of the Aegean Sea, the North A
egean islands, a loose grouping off the west coast of Turkey, the Dodecanese, another loose collection in the southeast between Crete and Turkey, the Sporades, a small tight group off the coast of northeast Euboea, and the Ionian Islands, located to the west of the mainland in the Ionian Sea. Eighty percent of Greece consists of mountains or hills, making the country one of the most mountainous in Europe. Mount Olympus, the mythical abode of the Greek Gods, culminates at Mytikas peak 2,917 m (9,570 ft), the highest in the country. Western Greece contains a number of lakes and wetlands and is dominated by the Pindus mountain range. The Pindus, a continuation of the Dinaric Alps, reaches a maximum elevation of 2,637 m (8,652 ft) atMt. Smolikas (the second-highest in Greece) and historically has been a significant barrier to east-west travel.
