Crosby is great at low tide or high tide. It's a long expanse of beach, the longest of Brewster's 8 bayside beaches. There is a long walking path and gorgeous vistas that on a clear day extend to Provincetown's monument. When the tide is out, you can walk miles across "the flats" for families and artists wanting a dramatic view. When the tide is in, the water is warmer by far than the Atlantic Ocean in mid-summer, and it is shallow enough in spots for young children to play and swim. If you like paddle-boarding, this is the place for you!
In addition, there is Nauset Beach for a dramatic view of the Atlantic Ocean and enough surf to suit the water sports crowd.
Of course there is also Sheep Pond and Long Pond, an easy walk from the house, with some of the clearest waters to be found on the Cape and the charming community beaches that are part of the neighborhood.
