Colorful boats, fresh seafood and balmy breezes are yours to enjoy during a harbor-based holiday. Here are five to consider.

1. MONTAUK Head to the end of Long Island for a relaxed experience in a beachy enclave where fishermen, surfers, urban hipsters and families easily mix in the salty air. Stroll along the docks to witness the arrival of the day’s fresh catch, as tony yachts and the occasional sightseeing boat, spouting the area’s seafaring history, inch into the harbor. Stay at the historic Montauk Yacht Club Resort & Marina, where all things nautical will serve as your holiday backdrop.

4. BALTIMORE Decades ago, this spirited Maryland city bolstered a movement to transform industrial waterfronts into tourist meccas where restaurants, shops and appealing attractions would soon energize the local economy. Today, visitors flock to the Inner Harbor, which serves the Chesapeake Bay. Family travel plans often include a visit to the National Aquarium, kayaking, sailing, windsurfing and feasting on the region’s famous blue crabs, oysters and clams.
