Is Port Isabel a good place to buy near South Padre?

Port Isabel sits on the mainland at the foot of the Queen Isabella Causeway, so the beach on South Padre Island is one bridge away. It is an old harbor town on the Laguna Madre with its own 1852 lighthouse, fishing boats and bayfront homes, usually quieter than the island.

The harbor town

Port Isabel began as El Fronton and became Point Isabel by 1850, shipping cotton out of the Lower Rio Grande. The brick Port Isabel Lighthouse went up in 1852. It is the only one of Texas's surviving historic lighthouses still at its original location and open to the public.

Why buyers look here

You live on the bay and drive the causeway to the beach. Port Isabel is where the boats, bait shops and seafood are, and the mainland side of the region's only road to South Padre Island.

Bayfront and canal homes

Much of what buyers want here is on the water: bayfront lots and canal homes with a dock on the Laguna Madre. The Laguna Madre is shallow, so check water depth and dock condition with any listing.

Insurance and flood

Port Isabel is in Cameron County, a first-tier coastal county for TWIA wind and hail coverage. Ask for flood zone and elevation details early.
