If you want the most hidden, serene and impossible-to-access beach, head south to Seabrook. The sands look the whitest, the board walks that lead perpendicular up the shore to the beach are the most quaint. It will just make you sigh. But so will the dearth of parking. If possible: Get dropped off, run, walk, cycle, ride a horse or take an uber, because parking is for Seabrook resident property owner and a non-resident property owners with placards only. Basically, impossible.
This review on TripAdvisor by Paul Y. says plenty: I’ve been coming to this beach for several decades — and I’ve always been fond of its quiet and pristine nature. It’s not busy like the beaches on either side of it — Hampton and Salisbury — so it’s nestled nicely in between the two. There isn’t the arcade and foot traffic activities that you see on the other two, and if you’re looking for a place to just enjoy the water, beach, and sun, this is the place for you.”
The fine print: There are no bathrooms, or other amenities to speak of. But the sand dunes are fantastic.
