In answer to your question, Glen Head is not actaully that close to the beach , it is a lttle over a mile and a half. There are other communities in the area, Glen Cove, Glennwood Landing, Sea Cliff, Glen Cove, Lattingtown, Mill Neck, Oyster Bay, Bayville, Cove Neck, Centre Island, and Oyster Bay Cove all near or on the water.
Alot will depend on your budget and how near the water you would like to be.

I would suggest you work with an agent because of one factor less of a headache for you. A realtor can help you find exactly what you are looking for including if you have any specific requirements (it could be anything). I hope this helps.
