About Cos Cob
This centuries-old Greenwich neighborhood, once called “Coscobneck”, was home to an Impressionist art colony from the 1890s to the 1920s. With water on two sides (the Cos Cob Harbor to the south and the Mianus River to the east) and hundreds of acres of parkland, the commuter-friendly village still feels worlds away from Manhattan.
Around 7,000 people live in this close-knit community on the banks of the Long Island Sound, and on nice days you’ll see many of them strolling through the streets—likely en route to one of Cos Cob’s many gathering places, like the seven-acre playground or the mom-and-pop cheese shop.
What to Expect:
Plentiful parkland, waterfront views, and thriving businesses.
The Lifestyle:
Everything within walking distance.
Unexpected Appeal:
A public park with a famous collection of conifers.
The Montgomery Pinetum is a huge draw for horticulturists because it’s home to about 100 different types of evergreens. The 61-acre swath also has miles of winding trails, a massive rock garden, and a picturesque picnic area.
The Market:
You'll Fall in Love With:
The locals’ infatuation with being on the water.
