Planting Fields-Oyster Bay: An overall great place to shoot year round.  Greenhouses, flowers, rose gardens, formal gardens and rolling landscapes.  Coe Hall Tudor mansion.  Seasonal events.

Caumsett State Park-Huntington: A hidden gem with formal gardens and horse stables.  Former home of Marshall Field III.  There are multiple buildings and an estate house.  Overlook the bluff to LI sound, hike down to the beach for classic rocky North Shore beaches.

Old Westbury Gardens-Old Westbury: Fabulous formal gardens with seasonal additions.  Rose gardens with sculpted walkways.  Ponds and fountains with waterlilies that attract dragonflies.  Bring a long lens and tripod.  Seasonal events.

Northport Harbor-Northport Village: Water views, sunsets, harbor views.  Quaint village, easy parking, dog friendly, Farmer's Market on Saturdays from June-November.

Sunken Meadow State Park-Kings Park: Atypical North Shore beach, sandy not rocky.  Sunrise and sunsets.  Boardwalk and jetty provide "leading lines" for photos.  Great place to shoot water fowl, egrets, osprey and blue herons.

Nissequogue State Park-Kings Park: Water views, marina and wildlife.  Additionally you can peruse the many abandoned buildings left behind from Kings Park Psychiatric Center.  Tons of urban decay.  Don't be afraid to explore!

Bayard Cutting Arboretum-Great River: Landscape photographers will love the scenery here, pond, wildlife, Tudor mansion.  In the fall there is a spectacular Dahlia Festival.

Lavendar by the Bay-East Marion: This is the only real lavender field on Long Island.  They have English and French lavender at the farm.  The English blooms first but call the farm to see when it is in bloom as it is contingent on the weather.  It's a bit of a drive so make a point to go to Greenpoint Village and visit any vineyard!

Old Bethpage Village Restoration-Old Bethpage: If you grew up on Long Isalnd you went here on a class trip in 4th grade (or your kids did!).  This is a hidden GEM!  Great all times of the year.  Cool barns, general store, blacksmith, farm with livestock.  Events all year round and the people that work there are very nice about taking photos of them.  So if you like portraiture this is a nice place to go.

Robert Moses State Park-Babylon: If you love beach photos, this is the place, all year round.  Go to Field 5 and shoot the lighthouse.  Famulous sunrise and sunsets.  Feeling ambitious - walk to Kismet!  Late September or early October monarch butterflies stop here on the way down south.  You can track them online or just look for the goldenrod in bloom and they are sure to be around.

Elizabeth Morton Wildlife Preserve-Sag Harbor: This is a great place for wildlife.  Bring some bird seed with you and just put it in your hand and you will be delighted to see chickadees and woodpeckers eat right out of your hand - so have your camera ready!  It's a bit of a drive for most of us, but make a day of it and visit Sag Harbor and take the ferry to Shelter Island.  When you go to Shelter Island there is a place where cactii actually grow, they have yellow flowers in bloom.

Sweetbriar Nature Center-Smithtown: Great seasonal flowers and butterfly conservatory.  The butterflies are seasonal and if you get there in the morning you will have the whole place to yourself!  Wildlife and resident birds on site.  Gardens and a short walk to the Nissequoge River.

The State Parks of New York (Long Island): This is a GREAT resource for finding ALL of the State Parks for New York State.  If you click on the heading for this it will give you a filtered view for all of the State Parks on Long Island.  Research, go and enjoy!!
