You don’t have to sing camp songs or toast marshmallows, but a small fire on the beach can be fun and romantic. Problem is, most beaches prohibit them. Sandy Neck Beach in Barnstable is a notable exception, but you have to check with the staff (508-362-8300) to see if weather conditions permit fires, which are limited to the area east of the public beach. The Cape Cod National Seashore issues a limited number of fire permits daily for the park’s six swimming beaches. Apply up to three days ahead at Salt Pond Visitor Center (508-255-3421, nps.gov/caco) for beaches in Eastham and Wellfleet, and at Province Lands Visitor Center.
