It is a rather long, but refreshing walk that can result in sightings of various hawks and owls. Fall is also a good time for Skaket Beach on Cape Cod Bay. Flocks of Brant and migrating Snow buntings often make appearances there. Finally, keep in mind that in summer it is better to get out early to avoid the beach crowds and the heat of day. The dead of winter is the time to go back to Nauset Beach to see rafts of offshore sea ducks including Eiders, Scoters, and maybe a few Harequin ducks.
Winter beaches are very cold, so dress warmly.
