Ask anyone who drives through Locust Valley in December and they will tell you the season looks different here. This community on the North Shore, where the land rolls down toward the harbors of Long Island Sound in the Town of Oyster Bay has a character all its own, and the best holiday displays work with it rather than against it.
Between the shops along Forest Avenue and Birch Hill Road and the quiet side streets, Locust Valley gives everyone plenty of reasons to slow down and enjoy the lights.

Locust Valley at a glance
Locust Valley belongs to the Town of Oyster Bay, one of the towns that make up Nassau County. It sits on the North Shore, where the land rolls down toward the harbors of Long Island Sound, away from the shoreline, with neighborhoods that feel settled and comfortable. Around town you will find a walkable downtown, older homes with real character and grand homes on generous lots.
Main routes such as Forest Avenue and Birch Hill Road carry much of the local traffic. Nearby you will find Lattingtown, Matinecock, Bayville and Glen Cove. All of that adds up to homes that deserve a display designed just for them, not one copied from the house down the street.
Holiday lighting ideas for Locust Valley properties
Good holiday lighting starts with the setting. Here is what we keep in mind for homes in Locust Valley:
Homes near the community center often sit close to the sidewalk, so entry decor, window details and porch railings are seen up close by people walking by.
Older homes in Locust Valley often have detailed trim, porches and multi-pane windows, and a design that traces those lines tends to look more natural than one that simply outlines the roof.
On a historic facade, warm white light flatters painted clapboard and cedar shingle, and a touch of color can be saved for wreaths, garlands or the front door.
Rooflines, windows, trees, shrubs and walkways can be combined in any mix, so the display can be as simple or as elaborate as you like.
On a deep lot the view from the road can be a long way from the house, so the design often starts at the entrance and builds toward the front door.
