Cities and towns
Nassau County is divided into three towns and two cities:
- North Hempstead, on the western portion of the North Shore, contains the "West Egg" and "East Egg" of Great Gatsby fame. Being that it borders Queens, it has a fair amount of development as well. It also includes the village of Mineola
- Glen Cove, a small city in the middle of Nassau County's North Shore, contains a lively downtown as well as several historic mansions.
- Oyster Bay is the easternmost portion of Nassau County. Its northern portion is centered around the hamlet of Oyster Bay on its eponymous harbor, and is again the site of many historic buildings. South Oyster Bay is more densely developed, but has many shopping districts and points of interest. It also includes the village of Farmingdale and the hamlets of Bayville, Bethpage, Massapequa and Plainview.
- Long Beach, Nassau County's other city, is prime beach territory right on the Atlantic Ocean.
- Hempstead is the nation's most populous civil township, and the second most populous municipality in New York. It is the site of Freeport's Nautical Mile, the "original suburb" of Levittown, and the famous Jones Beach. The Garden City area is known as the "Nassau Hub" due to its central location and concentration of shopping, athletic, and cultural activities. It also include the hamlet of Merrick and the village of Rockville Centre
Nassau County is the second largest county by square mile on Long Island (Suffolk being the largest by far). It is sandwiched between Suffolk County and Queens County. The County Seat is in Mineola. Nassau County also has several beaches, including Jones Beach and Long Beach. You can also visit the downtown areas of each village. There are typically many shops and sometimes even restaurants in those areas.
English is the main language. Hempstead, Uniondale, New Cassel, Westbury and Freeport have large Spanish-speaking populations.
Take the Long Island Rail Road, Nassau Inter County Express (formerly Long Island Bus) , or drive in via the Long Island Expressway, Northern State Parkway, Southern State Parkway, or Sunrise Highway.
Getting around is very easy by car, especially with the presence of the Long Island Expressway (commonly referred to as the LIE in the area) and several other parkways.
- Freeport Water Taxi. Summers, the water taxi connecting Freeport's Nautical Mile to Point Lookout is worth doing just for the ride. $20 adult fare, $10 for kids under 10, bar on board. They also operate a sunset cruise.
Nassau County is in general a safe place to visit. As anywhere, just use basic common sense; this is the average suburban county. Crimes, if any, usually occur in Hempstead, Freeport, Roosevelt, Uniondale, New Cassel/Westbury and Elmont. The Island Trees/Plainedge area of Levittown has seen an increase in crime lately, as well as the western part of Hicksville south of Cantiague Park. Gang violence is rampant in New Cassel, Hempstead, Uniondale, Roosevelt and Freeport. The only safe areas of Hempstead are west of Cathedral Ave, north of Hempstead Tpke and east of Westbury Rd, north of Hempstead Tpke. Uniondale and Roosevelt are safe in the daylight, but be extra careful at night. New Cassel is relatively safe during the day but very dangerous at night. Freeport south of Sunrise Hwy is very safe.
