Where can I go for whalewatching in/around(travel time ~1 h) New York City? I will be there in mid of July and i heared, that the whalewatching season starts at the beginning of July.
I would suggest expanding your range since 1 hour out of New York city won't get you very far along the coast. There are several places that say they offer but you might have to call them to see what they will actually offer.
Of course there is other kind of Whale Watching available as far as New York is concerned. :)
