A summer vacation to a beach in the American Southwest — is that a thing? If you don't reside in this area of the country, you're probably thinking all the sand in the Southwest is desert sand. Most of it is, but there are numerous slices of pristine ocean-side sand for you to enjoy. That's because the Gulf of Mexico is large, and its seaside spots are impressive. There are also ample lakes offering relaxation and fun beside the water. So, grab your swimming gear and sand-castle building supplies; it's time to shoot off to one of the best beaches of the American Southwest.

1. Padre Island National Seashore (Texas)

In many regions of the United States, people may debate which beach is the best. In the Southwest, many would agree that Padre Island National Seashore is the place to be if you're hanging by the sea. Why? Padre Island (pictured above) is the world's longest stretch of undeveloped barrier island, and that means plenty of space to sunbathe, ride the waves and fly kites.

If you're into turtles, you may be lucky enough to see the Kemp's ridley sea turtles nesting on the beach. The island also has over 380 species of birds, so bring your binoculars and try to spot everything from redhead ducks to snow geese. After your wildlife viewing, you can let out some energy with a gallop through the prairie land or run up the dunes.

Although this seashore is untouched, there are plenty of budget and luxury chain hotels nearby and in neighboring Corpus Christi, a great city to see during your trip as well. The area boasts over 50 restaurants and bars for you to choose from after the sun goes down; check out South Padre Island for everything from steaks and craft beer to tacos and margaritas.

2. Lake Mead National Recreation Area (Nevada)

When it comes to beach vacations in the American Southwest, it simply wouldn't be a list without Lake Mead, one of the world's largest man-made lakes. It's twice as big as Rhode Island! This lake, which was formed by the Hoover Dam's construction, is great for jet-skiing and boating, as well as beach sports like volleyball. Boulder Beach is the go-to spot for all such activities.

Lodging options range from houseboat rentals and campgrounds to cabins and resort accommodations. Even better, you can combine a trip here with a weekend of fun along the Las Vegas Strip; perhaps you'll get lucky at one of the casinos, and all your expenses will be covered. Now wouldn't that be awesome?

3. Blue Mesa Reservoir (Colorado)

It's not all about skiing in the Rocky Mountain State. Colorado is landlocked, but that big mountain range has formed some great bodies of water, and with that comes beaches — very nice beaches. Located along the scenic U.S. Highway 50, this reservoir forms the prettiest of pictures: After traversing through gorgeous high-mountain desert, the landscape opens up to sparkling blue water.

Top activities on the water include boating and water sports, as well as salmon fishing. Horseback riding and windsurfing are also common. The Old Highway 50 beach features some solid swimming locations, and the Bay of Chickens is great for reading and relaxing. Camping is one of the most popular ways to sleep here, but there are cabin rentals and RV parks beside the reservoir. Also, motels and hotels are available in nearby Gunnison.

4. Salt Lake City (Utah)

You knew the Great Salt Lake would make it on this list, didn't you? Summer, with its low humidity and sunny skies, is incredibly pleasant here, which makes hanging out on the Great Salt Lake's beaches a true joy. Antelope Island State Park, which showcases great hiking trails, excellent vistas and plenty of white sand, is the most popular location; it's also the place to camp.

Salt Lake City is right next door, so you can take in the city's fine culture after you've had your fun in the sun. The attractions around Temple Square are quite intriguing, the Salt Lake City Public Library is architecturally stunning, and Liberty Park is tranquil. Plenty of nice hotels are in the city if you want somewhere cozy to stay.

5. Galveston Island (Texas)

The Lone Star State has two destinations on this list, and for good reason. Galveston Island offers 32 miles of cozy sand along the Gulf of Mexico and has a wide variety of entertainment options to satisfy every sort of visitor. You can do everything from picnicking and fishing at Seawolf Park on Pelican Island to taking a nap beneath the sun on Stewart Beach and kayaking on the ocean waters. R.A. Apffel East Beach Park is another spot worth exploring, especially if sipping a cocktail and watching the waves roll into the shore is your thing.

To make your stay more convenient, Galveston provides every sort of lodging imaginable, from home rentals and RV parks to roadside inns and upscale hotels. There are also lots of other activities if you've had your fill of beach-bumming, including camping at Galveston Island State Park, shopping, wining and dining in The Strand historic district and touring museums such as the Galveston Railroad Museum.

Now you should be an expert on beach destinations in the American Southwest. All that's left to do is choose one, and go. Remember: Get yourself travel insurance from Allianz Global Assistance before you depart so you can swim, boat and fish without worry.
