See: Be sure to pack a nighttime picnic (rosé included) and head to the Wellfleet Drive-In for the evening's double feature. Bonus points if you have a hatchback Suburban and create a slumber party with pillows and blankets, as we did growing up.
Taste: Mac's on the Pier is an essential stop for my sisters and me. They have many locations, but we prefer to sit overlooking the docks with mozzarella sticks in hand. The fried seafood is wonderful, as are the views. (Also, BYOB!) Another must is PB Boulangerie for a pastry, a baguette, or three. Be sure to arrive early in the morning, and do your best not to get too carried away...
Smell: June brings the lovely scent of lavender to the Cape Cod Lavender Farm. Lavender season is brief, so I would recommend checking ahead to make sure the fields are still in bloom.
Hear: The Beachcomber is well known for great live music, and one of the most scenic beaches just down the dunes.
Feel: That ocean... As my mother still says, "Just get in. You'll feel better."
