Directions to the trailhead: On the north end of Padre Island, take Park Road 22 south to the national seashore entrance.  Pay the entrance fee, and look for the roadside parking area for the Grasslands Nature Trail on the right just inside the entrance station.  Park here.

The hike: At 113 miles in total length, Padre Island is the longest barrier island in the world, and it is also one of the most popular vacation and recreation destinations on the entire 367-mile Texas Gulf Coast.  Despite the City of Corpus Christi at its north end and the City of South Padre Island at its south end, most of the island is sparsely populated and undeveloped.  The island is named for Father Jose Nicolas Balli, who owned the island in the early 1800s and started several Catholic missions in south Texas.

            Today the core central 70 miles of Padre Island are protected as Padre Island National Seashore, which was established in 1962.  The national seashore's main attraction is its 65.5 miles of Gulf beach, all but 4 miles of which are open to 4-wheel drive vehicles.  True to the island's character, the national seashore is lightly developed: its amenities include only a Visitor Center and 2 small campgrounds with a total of 82 sites.

            A good time at Padre Island National Seashore can still be had by people without a 4-wheel drive vehicle.  The Visitor Center offers stairs leading down to the beach, and you will definitely want to visit this beach: it is my favorite beach on the entire Texas Gulf Coast.  Also, the parking lot for the Grasslands Nature Trail is located on the paved main park road just inside the park entrance station, which makes it a popular add-on before or after a day at the beach.  This trail forms the only hiking option in the national seashore (except for the beach, of course), and it offers a short, flat, and easy introduction to the barrier island's grasslands.

Trailhead for Grasslands Nature Trail

            From the roadside parking area, pick up the asphalt trail as it heads northwest into the grasslands.  A shelter with an information board that introduces you to the grasslands habitat stands at the trailhead.  Very quickly the trail splits to form its loop.  For no particular reason, I turned right and used the trail going left as my return route, thus hiking the loop counterclockwise.

Hiking through the grasslands

            The asphalt trail continues north on a meandering course through the grasslands.  Other than a few benches under small wooden shelters, there is no shade anywhere on this hike.  Fortunately, the close proximity of the Gulf somewhat moderates the south Texas heat, and a nice breeze is often present.  Bluestem is the most common grass in these grasslands, but blazing star, mistflower, and globe sedge also appear.  As you approach the north end of the loop, Laguna Madre and the Texas mainland can be seen across the grasslands ahead and to the right.

Heading into the dunes

Hiking along the dunes

            At 0.5 miles, the trail curves left and heads into the dunes portion of the hike.  The trail remains rather flat, but grass-covered dunes rise 20 feet high on the right.  These dunes add some interesting depth and vertical scenery to what is otherwise a very flat landscape.  At 0.8 miles, you close the loop, and only a short walk remains to finish the hike.  If you haven't already done so, make sure you take the short drive down to the Visitor Center and check out Padre Island's beach.
