Kayaking
Turns out NYC has enough kayak spots for each Real Housewife cast member to get a boat at a different pier and all meet at the end for "turtle time" and cat fights. But really, check out Piers 26, 44, 66, 84, and 96 for plenty of opportunities to kayak your nature loving heart out. Heading uptown? Skip the cab fare and kayak there.
