True to its name, Riverside runs along the eastern shore of the Mianus River. This is an almost entirely residential neighborhood in Greenwich, with a train stop conveniently located right in the middle. Houses south of I-95, closer to the train station and Long Island Sound, will generally command higher prices, while those north of the highway are smaller and touch more affordable. On either side though, properties are pretty, many on graceful, spacious wooded lots. Riverside is close to two of Old Greenwich’s parks: Greenwich Point Park, which has swimming, fishing, and a snack bar, as well as Binney Park, which has athletic fields and a playground. Houses can range from straightforward 1920s cottages to elaborate new construction estates. Many here belong to the Riverside Yacht Club, the second oldest sailing club in Connecticut, which also boasts a clubhouse with dining.
