Welcome to

Port Aransas

Picture wide stretches of sand, Gulf breezes rolling in off the water, and dunes swaying with sea oats. Port Aransas, known locally as Port A, rests on the northern tip of Mustang Island, a barrier island tucked between the Texas Gulf and Corpus Christi Bay. The horizon runs long and flat here, broken only by pelicans, shrimp boats, and the occasional dolphin fin.

Frequently ranked as one of the top 25 best beaches in the country, and one of the South’s best beach towns, Port A runs at a more relaxed pace than the larger city feel of Corpus Christi just an hour away. People come to Port A for the fishing, and it earns its nickname as one of the best saltwater fishing towns in Texas.

Beyond the reels and rods, you'll find golden beaches, birdwatching at the Leonabelle Turnbull Birding Center, and fresh Gulf seafood served just steps from the water. Enjoy sinking your toes into Port A’s remarkably soft sand while catching live music to enhance the coastal vibe. Music is such a part of Port A’s character, the Texas Music Office has designated this small beach town as a “Music Friendly Community.”

Long before Port Aransas was a popular vacation spot, it was home to the Karankawa people. Later, it grew into a fishing and shipping port in the 1800s, while the historic Lydia Ann Lighthouse was built in 1857. Today, it still guards the channel and remains one of the region's most photographed landmarks.

In addition to its laidback beach lifestyle, another reason this area is so popular with visitors is because of its annual events. The Texas SandFest brings world-class sand sculptors to the beach each spring, while the Deep Sea Roundup, the oldest fishing tournament on the Texas coast, reels in anglers every July. Add island art shows and seafood festivals, and there's always a reason to visit.

When you’re ready to trade your routine for salt air and sunsets, book your Port Aransas stay with Casago Third Coast and settle into its easy-going island life.

Frequently Asked Questions

What makes Port A so popular is that there’s never a bad time to visit. For example, spring and fall bring warm days, smaller crowds, and comfortable water temperatures. Summer is the busy season, which attracts plenty of beach lovers, turning the quiet island into a rhythm of activity. If you’re an angler, then late spring through early fall is your best time to land the big one!

Most visitors fly into Corpus Christi International Airport (CRP), about 30 minutes away by car. Additionally, the San Antonio International Airport (SAT), is about a 2.5 hour drive from Mustang Island. You can also drive in over the JFK Causeway or hop the free ferry from Aransas Pass for a scenic arrival.

Port A is one of the beaches in Texas where you can drive on the beach, but only on the outside of a system of posts (bollards) set up to separate a driving lane from rec areas. The speed limit for driving on sections of the beach is 15 MPH, and be sure to pick up a beach parking permit for $12. Permits are available at the Port A Visitor Center, City Hall, and a number of local shops and convenience stores around town.

At the top of most vacationers' itineraries are fishing charters, beachcombing, and birdwatching. You can also rent a golf cart to cruise around town, take a dolphin-watching tour, or spend the day paddleboarding in the calm bay waters.

A car helps for beach trips and exploring the island, but many visitors rent golf carts to zip around town. The compact downtown area is also easy to explore on foot once you've settled in.
