A New England gateway, bordering New York's Westchester County, it is a prime location for convenient travel by rail or highway to major metropolitan centers.

The fifty square miles of this wealthy and diverse community stretch from the backcountry to the Long Island Sound and encompass several villages or hamlets, each with its own distinct identity and geography; Greenwich proper (downtown Greenwich), Cos Cob, Riverside and Old Greenwich.  

The village of Old Greenwich was called "Sound Beach" in the last century, and the main road through the small downtown business section is Sound Beach Avenue. This street serves as a popular hangout for children and teenagers as well as hosting annual street fairs and events. Fortunately, much of Old Greenwich retains its "vintage" charm. Old Greenwich resists the fate of being just another "suburb of New York City". 

The rambling estates and vast manors of historic Cos Cob, Old Greenwich and Riverside dot the coastline. The rolling hills and manicured properties of Banksville and Round Hill offer exceptional properties in a range of styles and sizes, from large country houses to streamlined contemporaries and condominiums while smaller cottages and charming condominiums grace the coast. Inland, the architecture and landscape are equally desirable. Blending seamlessly with the city's residential community are the corporate offices of hedge funds, businesses and respected industrial firms.

Many independent and parochial schools compliment the town's high-achieving, well-funded public school system and Adult and Continuing Education.

The town has an abundance of leisure and cultural activities. Located in town are four public and numerous private beaches on Long Island Sound, swim clubs, two inland lakes plus municipal and private marinas. There are numerous public parks and trails for hiking, picnicking, rollerblading, bicycling and horse-back riding. There are five country clubs with golf courses and the town owns the 18-hole Griffith E. Harris golf course. Babcock Preserve is a popular 297 acre park that offers a variety of activities including up and down trail walking, running, hiking, and cross country skiing.
