From the bustling beaches of Galveston to the serene shores of Matagorda, Texas’ islands offer a diverse range of experiences for nature lovers, history buffs, and adventure seekers alike.

In this article, let us take you on a journey through the largest islands in Texas, and uncover their unique charm and the must-see attractions that make them worth a visit.

Padre Island (113 miles)

The entrance to South Padre Island

Picture this: endless turquoise waters meeting pristine white sands, stretching as far as the eye can see. That’s Padre Island, the world’s longest barrier island and Texas’ largest gem.

At a whopping 113 miles long, Padre Island spans from Corpus Christi and Padre Island National Seashore in the north to lively beach bars and thrilling theme parks in the south. This island is so huge it dwarfs the state of Delaware. It offers a blend of urban adventures, serene natural escapes, and everything in between.

Because it’s a big island, it’s divided into two: the North and South Padre Island.

North Padre Island

Starting in Corpus Christi, North Padre Island is a bustling hub with attractions like the Selena Museum, the Texas State Aquarium, beachside breweries, and tours on the historic USS Lexington. Here, the Padre Island National Seashore showcases the world’s longest undeveloped barrier island stretch. This 66-mile park is a haven for sea turtles and hundreds of bird species and offers fantastic fishing, kayaking, windsurfing, and primitive camping experiences. With over 1,000 campsites across five camping areas, it’s a nature lover’s paradise.

South Padre Island

Famed as both a spring break hotspot and a family-friendly destination, South Padre Island is easily accessible via State Highway 100 from Port Isabel. This southern stretch is packed with hotels, resorts, carnival rides, and beach bars. Highlights include a massive water park and Gravity Park, home to the world’s tallest reverse bungee. Adventurers can enjoy fishing, kayaking, stand-up paddleboarding, and windsurfing.

One of the most enchanting experiences on South Padre Island is the sea turtle hatchling release, occurring from mid-June to August. Witnessing these rare Kemp’s Ridley sea turtles make their way to the ocean is a magical sight. The Malaquite Visitor Center offers programs educating visitors about sea turtles and conservation efforts.

Whether you’re seeking thrilling activities or peaceful retreats, Padre Island offers an unmatched blend of attractions that truly embody the saying, “Everything’s bigger in Texas.”

Matagorda Island (38 miles)

Matagorda Island, Galveston’s lesser-known sibling, is a hidden gem perfect for those seeking adventure off the beaten path. Accessible only by boat, this remote island spans 56,688 acres of pristine barrier island and marshes along the bay. It’s a paradise for campers and adventurers ready to embrace a rugged experience without electricity or running water.

Trade modern conveniences for the joy of saltwater fishing, seasonal hunting, bird watching, and stargazing. Matagorda Bay Nature Park is a haven for outdoor enthusiasts, offering numerous hiking and walking trails. After working up a sweat, cool off by renting a kayak and exploring the refreshing waters.

Wildlife lovers will be thrilled by the island’s several refuges, home to over 15 threatened or endangered species. As night falls, the island’s remote location and minimal light pollution make it perfect for stargazing, revealing a breathtaking celestial display.

Remember, Matagorda Island’s beach is primitive, so bring all necessary supplies and ensure you pack out all your trash. A four-wheel-drive vehicle is essential to navigate the sandy terrain without getting stuck.

Galveston Island (27 miles)

Galveston Island's Pleasure Pier in Galveston, Texas

Galveston Island is the ultimate family getaway, perfect for those craving sun, sand, and endless fun. As the northernmost barrier island, it attracts over 7 million visitors each year, making it Texas’ favorite island destination. Its popularity is largely due to its proximity to Houston, making it an easy escape for city dwellers. Nicknamed “Playground of the South” and “Ellis Island of the West,” it’s an intriguing destination for families and couples alike.

Despite its quirky charm—with eccentric mini-golf courses, vibrant sea turtle statues, and a pyramid-shaped aquarium reminiscent of Atlantic City—Galveston offers so much more. Kids will be thrilled by Moody Gardens, an entertainment complex featuring an aquarium, a rainforest, and a discovery center. The world’s first “convertible waterpark,” Schlitterbahn, and the iconic Pleasure Pier, with its thrilling carnival rides perched over the water, add to the island’s allure.

For history buffs, The Strand, Galveston’s historic bayside district, offers stunning Victorian and Greek Revival architecture. This area is brimming with shops, restaurants, and art galleries. The Grand 1894 Opera House, an ornate theater, hosts a variety of performances. Further south, Jamaica Beach provides a peaceful retreat from the bustling tourist spots, perfect for serene sunbathing away from the crowds.

San José Island (21 miles)

San José Island is just as untouched as Matagorda but much easier to get to. Situated across from Port Aransas, this privately owned island is a treasure for those seeking a unique and secluded experience. With most of the island off-limits to the public, it’s perfect for anyone craving solitude on the beach. The island’s pristine, untouched sandy shores and obvious waters are among the clearest in the state, making it a hidden gem worth exploring.

It offers 21 miles of untouched beachfront, providing excellent fishing opportunities for redfish and trout, especially near the rugged North Jetty. Seashell enthusiasts will love beachcombing along its shores.

For a $12 round-trip, Jetty Boat ferries visitors from Fisherman’s Wharf in Port Aransas. Since there are no amenities on the island, it’s crucial to pack all necessary supplies and leave no trace to maintain its pristine condition. Cozy cottages in Port Aransas offer accommodation nearby, with waterfront neighborhoods perfect for exploring, dining, and shopping.

This beautiful island is also steeped in history. It was the first place in Texas to fly the American flag, planted by a lieutenant from the USS Alabama in 1845. The island once hosted a short-lived town called Aransas, which was destroyed during the Civil War. In 1935, oil magnate Sid Richardson established a ranch and estate here, entertaining notable figures like President Franklin D. Roosevelt. While the estate is gone, legends of buried treasure from the pirate Jean Lafitte add to the island’s mystique.

Mustang Island (18 miles)

With its powdery white sands, deep blue waters, and majestic green dunes, Mustang Island is one of the Gulf Coast’s most breathtaking spots. This barrier island is a wildlife haven, home to migratory birds, white-tailed deer, sea turtles, armadillos, jackrabbits, and over 600 species of saltwater fish. Whether you’re into kayaking, swimming, fishing, hiking, bird-watching, or camping right on the beach, Mustang Island offers a plethora of activities.

It’s also a favorite for spring break and summer vacations, and it’s easy to see why. The beaches are stunning, the waters teem with colorful fish, and there’s even a resort village that feels like a tropical paradise. Every April, Port Aransas hosts SandFest, where talented sculptors create elaborate sandcastles. You might even come across some buried treasure, as this area was once frequented by pirates.

Even if you don’t find hidden loot, you’ll discover other treasures: awe-inspiring sand sculptures, thrilling jet ski adventures, and abundant shrimp and redfish to satisfy your seafood cravings. Port Aransas, with its year-round population of about 3,000, charms visitors with its vibrant atmosphere and unique quirks. During SandFest, enjoy carnival treats, live music, and giant sandcastles.

Follet’s Island (13 miles)

Stretching over 13 miles between Surfside Beach and San Luis Pass, Follet’s Island is a year-round haven for nature lovers. Whether you’re into fishing, swimming, or camping, this “free” beach offers natural beauty and serenity. Easily accessible via Bluewater Highway (County Road 257), it’s a picturesque destination that promises a tranquil escape.

Unlike the bustling Galveston, Follet’s Island remains mostly undeveloped, featuring only a few remote beach houses perfect for a peaceful getaway. The island is a vast, open beach, ideal for swimming, beach camping, fishing, and kayaking. With its undeveloped charm, visiting and camping here are entirely free of charge.

Since the island lacks hotels and restaurants, visitors need to bring their supplies. There’s no electricity or running water, so self-sufficiency is key. If you’re seeking a unique, off-the-beaten-path destination, Follet’s Island is a fantastic choice.

Brazos Island (4 miles)

At just four miles long and 217 acres, Brazos Island is the smallest of Texas’ barrier islands. This tiny island, located north of the Rio Grande’s mouth, offers a serene escape from city life with opportunities for swimming, fishing, bird watching, and dolphin spotting.

Camping spots are available for overnight stays. Recently, the island has gained popularity due to its proximity to SpaceX’s Boca Chica launch facility. Visitors can often witness rocket launches, adding a thrilling twist to their visit.

Pelican Island (2.8 miles)

Pelican Island, linked to Galveston by a bridge, is a small island with big attractions. Home to Texas A&M University at Galveston, the island features two Navy warship memorials—USS Stewart and USS Cavalla—converted into museums at Seawolf Park. This park is rich in preserved war artifacts, making it a fascinating spot for history buffs.

Beyond its historical sites, Pelican Island is perfect for fishing, bird watching, and beach relaxation. With various bird species like pelicans, egrets, and herons and lovely beaches for sunbathing, the island offers a delightful mix of learning and leisure.

Pelican Island is a fantastic destination for history enthusiasts, nature lovers, or anyone looking to unwind by the sea.
