"The Cape Cod National Seashore is one of the best things to do on Cape Cod, and it’s one of Palmer’s favorite parks to experience in the fall. 'Visiting an area best known for its beaches during the fall may seem counterintuitive, but it’s definitely worth consideration,' he says, noting that the area’s cooler temperatures 'only make the local clam chowder more delicious' this time of year. 'September and October are also still peak season for the Cape’s growing population of great white sharks, so a nice long walk on the beach could well result in a sighting of these awesome predators,' he adds." - Travel + Leisure Editors
