Vouliagmeni is an exclusive municipality 20 km south of Athens. Its population is about 4,000. It sits on the southwestern part of the Hymettus mountain range. It's exact location is around 37.8° or 37°48′ N and around 23.83° or 23°50′ E.
Vouliagmeni is bisected by Athinas Avenue, which arrives from Athens as Vouliagmenis Avenue, then runs parallel to the seashore and continues southwards. The part east of the main road is rocky and the bulk of the town is built there. The western half is covered with pine trees, and consists of two peninsulas, Megalo and Mikro Kavouri ("Big Crab" and "Little Crab"). The two Kavouria feature beautiful and very popular sandy and pebble beaches in between rocky shores, several luxury hotels including the Astir Hotel which occupies most of Mikro Kavouri, two marinas, a nautical club (swimming, finswimming, waterpolo, skiing, sailing), a sports club (football, basketball, volleyball, tennis) and several luxurious seaside restaurants, taverns and cafeterias. The Kavouria are among the most expensive pieces of housing real estate in Greece. Zoning is enforced strictly.
The Vouliagmeni beaches are consistently awarded the coveted EU blue flags for environmental excellence. The triathlon of the 2004 Summer Olympics took place in this area.
