At dusk. Like 7 pm.
Sunset
I think around 7pm but i dont think you can get a great view of Manhattan. You can get great view of GW bridge
Sunset like most parks I'm pretty sure
You really won't be able to get a great photo of New York, itself if I remember, correctly. But you can get great photos of the Hudson river and the George Washington Bridge.
At sunset.
