Cape Cod is a better place for two people than for twenty, and it is at its best in the months when families cannot come.
That is not a consolation prize. The things that make this peninsula romantic — an outer beach with nobody on it, a long low light across dune grass, a dozen oysters and a fire, a room in a house built by a sea captain — are all improved by the absence of a crowd. In July the same beach has a full car park and the same restaurant has a ninety-minute wait. In the second week of October you can walk two miles of Atlantic shore and meet four people, and the sea is still warmer than it was in June.
The Cape also has a geographical trick that couples should know about. Because the peninsula curls back on itself, its bay shore faces west. On a coastline where the entire American convention is sunrise over water and sunset behind the land, Cape Cod Bay gives you the sun going down into the sea. Herring Cove in Provincetown, First Encounter in Eastham, Rock Harbor in Orleans and the Dennis bay beaches are all evening destinations, and locals treat them as such — people drive to them, sit on the bonnet of the car and applaud.
Then there is Provincetown, which is unlike anywhere else in New England and should be part of any couples trip here. It is a working fishing port, one of the oldest art colonies in the country, and one of the longest-established LGBTQ+ destinations in the United States. At the 2010 census it recorded the highest proportion of same-sex couples of any municipality in America. Three and a half thousand people live there year round and many times that arrive in August. Commercial Street, laid out at twenty-two feet wide in 1835 and never widened, runs three miles end to end and is the best evening walk on the Cape.
The rest divides between the two halves of the Cape's character. Along the bay from Sandwich to Brewster, Route 6A is the Old King's Highway: antique shops, captains' houses, marsh views and inns in buildings that predate the republic. Out on the Outer Cape it is dunes, lighthouses, oysters and weather.
What follows is organised by what kind of evening or day you are after, with a bias toward the shoulder season, because that is the honest recommendation.
