The Empire State Building observation deck is an excellent vantage point from which to see Manhattan, whether it be by daylight or to see the city lights.
The deck is open from early morning until late at night, with extended summer hours.
Admission prices vary by age, but adults get in for $16. The ticket office was on the 2nd floor of the building.
We only visited the observation deck, but the building also hosted some restaurants and shops, including a post office in case you want to send off some postcards.
The lighting of the Empire States Building varies at different times of the year and depending on the occasion, may be red, white, blue, green, yellow, purple, and more. And, it doesn't have to be a traditional holiday, like Valentine's Day, it may also be lit up to bring awareness to breast cancer, Alzheimer's disease, AIDS, and other causes.
