Cape Cod National Seashore, and some neighboring towns, require that pets be leashed at all times. Specific areas where pets are prohibited are posted. Ask at seashore visitor centers or ranger stations about restrictions that apply.
Here is a link to a brochure about Cape Cod National Seashore's pet policy.
Did You Know?
The area at the northernmost tip of Cape Cod National Seashore in Provincetown is known as “Race Point”. It gets its name from the swift tidal “race” that swirls from ocean to bay around the point. The swimming beach is located a safe distance away in calmer waters.
