America's Most Scenic Roads

Route 6, Massachusetts

This 117-mile route links Cape Cod’s network of sand dunes, beaches, marshes, tidal ponds, and quaint fishing towns. You can follow it to Provincetown’s music festivals and art galleries, to the bay side for family-friendly beaches, or ocean-side for panoramas of the Cape Cod National Seashore.

Stop: Book a summertime whale-watching boat tour and keep your eyes peeled for a big-winged New Englander or humpback whale. (whalewatch.com; $42)
