Welcome to Port Isabel, TX

Port Isabel sits at the southern tip of the Texas Gulf Coast on the Lower Laguna Madre, connected to South Padre Island by the Queen Isabella Causeway and to the Gulf of Mexico via Brazos Santiago Pass. It is the last stop on the ICW before the Port of Brownsville, which handles primarily commercial traffic. For cruising boaters, Port Isabel is the practical southern terminus of the Texas coast.

The 1852 Port Isabel Lighthouse stands in the center of downtown, half a block from the water — the last Texas lighthouse open to the public and a navigational landmark that has guided vessels through Brazos Santiago Pass for more than 170 years. The waterfront retains its working character: shrimp boats, commercial fishing operations, and marine services share the harbor with recreational boats.

For anglers, the Lower Laguna Madre is the primary draw. The area holds the only year-round snook fishery in the continental United States outside of Florida, alongside redfish, speckled trout, flounder, black drum, and mangrove snapper on clear, shallow grass flats. The Brazos Santiago Pass is the seasonal home to tarpon from April through November, with fish ranging from 20 to 200 pounds during peak months of July through October. The hypersaline waters of the Laguna Madre produce exceptional water clarity, making sight-fishing the flats a distinctive experience on this part of the Texas coast.

Marina options include Sea Ranch Marina II at Southpoint, the Port Isabel City Dock, Pelican Point Marina, and the Laguna Madre Yacht Club. Ashore, the waterfront has seafood restaurants and the Museums of Port Isabel complex, which includes the lighthouse, the Port Isabel Historical Museum, and the Treasures of the Gulf Museum documenting three Spanish shipwrecks lost offshore in 1554.
