Where Old Town is, and how it feels
Old Town is the compact, low-rise downtown at the north end of Mustang Island, tucked on the bay side where the Corpus Christi Ship Channel meets the town. It grew up around the harbor long before the beachfront condos and planned communities arrived, and it still reads that way: a flat, easy grid you can cross on foot or by golf cart in a few minutes, with Alister Street as its main commercial spine and shorter streets branching toward the water.
Because it started as a working fishing settlement, Old Town mixes uses the way older towns do. Bait stands and boat slips sit a block from galleries and coffee. Family-run restaurants share the street with tackle shops, real-estate offices, and the post office. It is the part of Port Aransas where you are most likely to run errands, eat, and sightsee without ever getting back in the car.
The harbor, the ferry, and Roberts Point Park
The harbor is Old Town's anchor. Charter boats, shrimpers, and private craft work out of the marina, and it is the launching point for most of the town's fishing and dolphin-watching trips. On the channel side, Roberts Point Park gives you an open lawn, a fishing pier, and one of the best free vantage points in town to watch tankers and barges slide through the ship channel — a genuinely local way to spend a sunset.
The free Port Aransas ferry lands here too, carrying vehicles and pedestrians across the channel to Aransas Pass around the clock. That makes Old Town the natural first and last stop for anyone arriving by the ferry route, and it is why the neighborhood tends to fill and empty with the ferry line during peak weekends.
History you can still walk to
Old Town carries most of the island's visible history. Farley Boat Works, once a builder of wooden fishing boats, has been revived as a working shop and museum tied to the Port Aransas Museum, which tells the story of the island's fishing and hurricane past a short walk away. The Tarpon Inn, dating to the late 1800s and listed on the National Register of Historic Places, is famous for the thousands of signed tarpon scales that line its lobby — including one credited to a 1937 visit by President Franklin D. Roosevelt.
The town's scientific side lives nearby as well: the University of Texas Marine Science Institute sits at the north edge of town, and its public-facing programs make the connection between Port Aransas and the surrounding bays and estuaries easy to see. Together these places give Old Town a sense of continuity that the newer, purpose-built parts of the island can't match.
Eating, shopping, and getting around
Old Town holds a large share of the town's independent restaurants — breakfast spots, seafood kitchens, casual bars, and coffee shops — clustered tightly enough that you can walk between several in an evening. Shopping runs to the local end of the spectrum: beach outfitters, art galleries, gift shops, and markets rather than chains.
The neighborhood is built for low-speed travel. Parking downtown is mostly free but tightens on peak weekends, so many visitors leave the car and move by golf cart, bike, or on foot. If you want a base where you can eat, browse, and reach the harbor without driving, Old Town is the most walkable choice on the island.
