This is one of my favorite parks in all 5 boroughs. It is a 2.5min subway ride from Grand Central (take the 7 toward Queens and get off the 1st stop: Vernon-Jackson, exit and walk toward the water). You have the entire skyline in front of you. It's a wonderful place to bring the paper/a book, to tan, etc. If you have children, there is even a little park for them, too. Gantry has a wonderfully maintained landscaped area along the piers, and there are several great restaurants either on the water or a few blocks back (near the subway entrance). To me, what makes it so appealing is that there little if any traffic, so you have a perfect view of the Manhattan, which makes it one of the best romantic date spots.
