Austwell, Texas · 38 miles from Rockport
Aransas National Wildlife Refuge
115,000 acres of Texas Gulf Coast wilderness. The only wintering ground of the world’s last wild flock of Whooping Cranes. And a federal website that buries everything you actually need to know before you go.
Read This Before You Drive Out There
Getting There from Rockport
The refuge entrance is at 1 Wildlife Circle, Austwell, TX 77950. It’s a straightforward drive but the final turns are easy to miss — especially since you’ll have no GPS signal once you’re close. Set your navigation before you leave town.
Pro tip: the Visitor Center staff know exactly where cranes were spotted that morning. Stop in before you drive the loop.
The Auto Loop — 16 Miles Through the Refuge
The centerpiece of any refuge visit is the 16-mile paved auto loop. A regular car handles it fine — no four-wheel drive needed. You can drive it straight through in about 45 minutes, but plan on 2–3 hours if you stop at the pullouts and trails along the way. Most people don’t stop enough and regret it.
The loop passes through every habitat type on the refuge: live oak mottes, freshwater ponds, coastal prairie, and tidal flats with wide views of San Antonio Bay. Wildlife is present at every stop — the question is just whether you’re patient enough to find it.
The auto loop — open coastal prairie scrub, flat horizon, and wildlife that crosses without warning. Feral hog sightings are common.
Best Spots for Wildlife — Ranked
The single best spot on the refuge for whooping crane viewing — better than the tower. The trail follows the edge of the bay flats where cranes feed in winter. You're at ground level looking across the water, which gives you a more intimate view than the elevated tower perspective. Easy walk, flat terrain.
The tower gives you the widest panoramic view of San Antonio Bay and the surrounding marsh. Spotting scopes are provided. On a clear winter morning you can see cranes, spoonbills, and shorebirds spread across the bay flats. Good for scanning large areas — Heron Flats Trail is better for close views.
The most reliable alligator spot on the refuge. Multiple gators are almost always visible from the viewing platform. Year-round access — alligators don't migrate. Keep pets away from the water's edge and don't approach the animals.
Mixed habitat trail that passes through live oak mottes and open grassland. Good for resident songbirds, deer, and the occasional javelina. One of the more varied habitat experiences on the refuge.
Woodland trail through coastal live oaks. Great for migrant songbirds in spring and fall. Wrens, vireos, warblers during migration. Resident cardinals, Carolina Wrens, and Rufous-crowned Sparrows year-round.
Bay access point with good views of wading birds and waterfowl on the water. Named for the yucca plants (dagger plants) that grow along the trail. Worth a stop at the end of the loop.
The 40-foot observation tower at the end of the auto loop — spotting scopes provided, wide views of San Antonio Bay
Whooping Crane Season — What to Expect
The Aransas-Wood Buffalo flock — the only self-sustaining wild flock of Whooping Cranes on earth — arrives at the refuge in October and stays through April. There are currently 560+ birds. This is the entire wild population wintering in one place. Nothing else in North American birding compares.
Peak viewing is December through February. The cranes spread across the refuge’s tidal flats feeding on blue crabs and wolfberries. From the Heron Flats Trail and observation tower, views range from 100 to 400 yards — bring a scope or powerful binoculars. The birds are unmistakable: five feet tall, pure white, red crown, black wingtips. Nothing else looks like them.
Realistic expectations:
Whooping Cranes at dawn on the refuge marsh — the world’s entire wild flock winters here, October through April
What Else You’ll See
Roseate Spoonbills and Great Blue Herons on the tidal flats — year-round residents on the refuge
Alligators are reliable at the designated viewing area year-round — keep pets away from the water’s edge
⚠️ Drive Carefully After Dark
The roads between the refuge and Rockport — especially FM-774 and the TX-35 corridor through Lamar — have some of the highest wildlife crossing volume on the Texas coast. Deer, feral hogs, and armadillos move at dusk and after dark. Cell service is essentially zero from FM-774 all the way back to Lamar. Let someone know your plans before you go, don’t speed on the return drive, and watch the shoulders. This is genuinely remote Texas — plan accordingly.
