When people think of Texas, they usually picture big cities, BBQ, and endless stretches of desert—but not islands.
Surprisingly, Texas has several islands with sandy beaches, crystal-clear lakes, fishing spots, and a few places where wild dolphins or sea turtles might pop up to say hello.
Some offer off-the-grid adventures and untouched nature, while others have laid-back beach towns, fresh seafood, and perfect sunset views.
Whether you’re kayaking through hidden coves, driving your Jeep straight onto the sand, or relaxing by the water, these Texas islands are about to blow your mind.
1. South Padre Island
South Padre Island is a skinny barrier island off the southern tip of Texas, famous for its white sandy beaches, warm Gulf waters, and epic sunsets.
From high-energy spring break bashes to peaceful dolphin-watching, this spot offers the best of both worlds.
The island’s main drag, Padre Boulevard, is packed with seafood joints, beach bars, and fun shops selling everything from surf gear to hot sauce shaped like Texas.
If you’re into adventure, you can try parasailing over the ocean, ride an ATV through the sand dunes, or experience the buzzing nightlife.
Don’t miss Sea Turtle, Inc., a rescue center where you can meet and learn about the adorable sea turtles that will get released back into the wild.
2. Padre Island
Padre Island, just north of South Padre, is a totally different atmosphere—way less party, way more nature.
It’s home to Padre Island National Seashore, the longest stretch of undeveloped barrier island in the world, where you’ll find rolling sand dunes and coastal prairies.
This is the place to camp on the beach, spot rare Kemp’s ridley sea turtles, and watch pelicans cruise over the waves like they own the place.
If you’ve got a four-wheel-drive, you can hit the 60-mile-long beach drive, where the further you go, the more it feels like you’ve landed on a deserted island.
And since the stargazing here is off the charts, don’t be surprised if you end the night lying in the sand, staring up at the Milky Way, and forgetting you’re still in Texas.
3. Mustang Island
Just up the coast, Mustang Island offers that perfect mix of beachy relaxation and outdoor adventure, with a bit of small-town charm thrown in.
The island’s biggest draw is Mustang Island State Park, where you can kayak through winding coastal trails, camp on the sand, or cast a fishing line straight into the surf.
If you want a break from the wilderness, head to Port Aransas, the island’s only town, where you’ll find colorful beach cottages, fresh shrimp tacos, and a laid-back vibe.
Dolphins love to hang out in the bay, and if you hop on a ferry or boat tour, there’s a good chance they’ll pop up alongside you to say hello.
If you’re visiting in February, keep an eye out for the Whooping Crane Festival, celebrating the return of these rare, gangly birds that somehow look majestic.
4. San José Island
Right across the channel from Port Aransas, San José Island feels like a secret getaway, mostly because it kind of is.
This privately owned island is open to the public for day trips, but there are no restaurants, no hotels—just miles of untouched beaches and top-notch shell-hunting.
The ferry from Port Aransas drops you off on the edge of the island, where it’s just you, the waves, and maybe a few fishermen trying to reel in a monster redfish.
Birdwatchers love this place since it’s a major stop for migrating shorebirds, and if you’re lucky, you might even spot a roseate spoonbill.
It’s the kind of place where you leave your phone on airplane mode and let the sound of the waves remind you why the state’s beaches are seriously underrated.
5. Matagorda Island
If you’re looking for true off-the-grid adventure, Matagorda Island is where it’s at—no roads, no shops, and definitely no WiFi, just pure, untouched Texas coastline.
You can only get here by boat, which keeps the crowds away and makes it feel like your own private island, perfect for fishing, birdwatching, or just enjoying the total silence.
One of the coolest spots is the Matagorda Island Lighthouse, a 19th-century tower that’s been standing tall through hurricanes, strong winds, and Texas history.
With miles of untouched shoreline, it’s a goldmine for beachcombers—think seashells, driftwood, and the occasional sand dollar waiting to be discovered.
Whether you’re paddling through the shallow bays, spotting wild deer roaming the dunes, or setting up camp under a blanket of stars, this place is pure magic.
6. “The Island On Lake Travis”
While this isn’t your typical ‘island’, you’ll definitely feel like you’re on one.
And with the beautiful Lake Travis on your doorstep, you won’t be complaining that we told you about this place.
The Island on Lake Travis is a luxury resort community with Mediterranean-style villas, palm trees, and a full-service spa.
Boating is the main event here, so whether you’re wakeboarding, cruising on a pontoon, or just floating with a drink in hand, this lake life is all about taking it easy.
And for the best views and sunset in the state, head to Oasis Texas Brewing Company, which is perched high on the cliffs.
