Way down at the bottom of the Texas coast, where the Queen Isabella Causeway leaves the mainland for South Padre Island, a white brick lighthouse stands on a little rise above the water. The Port Isabel Lighthouse has watched over the Laguna Madre since 1852, and you can still climb to the top.
It’s the anchor of an easy, unhurried coastal day: a climb, a museum, a boat ride or a fishing pier, and seafood with a view of the bay. Here’s how to put it together.
Getting to Port Isabel
Port Isabel is a small fishing and shrimping town in Cameron County, right at the foot of the causeway. It’s about half an hour northeast of Brownsville and roughly an hour and a quarter from McAllen. From Corpus Christi, figure close to three hours, and from San Antonio about four and a half.
Fall and winter are a fine time to go. The weather stays mild, the summer crowds are gone, and the Rio Grande Valley fills up with winter visitors who come for exactly that reason.
Climbing the Port Isabel Lighthouse
The lighthouse was built in 1852 to guide ships through Brazos Santiago Pass. During the Civil War, soldiers from both sides used it as a lookout. The light went dark for good in 1905, and the state opened the site to the public in 1952. Today the Texas Historical Commission owns it as the Port Isabel Lighthouse State Historic Site, and the City of Port Isabel runs it day to day.
Getting to the top means about 75 winding steps plus a few short ladders near the lantern room. Up there you’ll find a working replica of a third-order Fresnel lens, installed in 2022, and a wraparound view of the Laguna Madre, the causeway and the ship channel.
A few rules to know before you go:
- Children must be at least 5 to climb, and adults can’t carry a child up or down the stairs.
- The tower closes in wet weather, and the upper catwalk may close on high-wind days.
- Tickets are sold at the Keeper’s Cottage or the lighthouse, by credit or debit card only.
Don’t skip the Keeper’s Cottage at the base. It’s a replica built from the original 1855 floor plans, and it serves as the visitor center, with exhibits and restrooms.
Getting to know the Laguna Madre
The Laguna Madre is the long, shallow, salty bay tucked between the Texas mainland and Padre Island. It’s prime territory for anglers, birders and bottlenose dolphins, and Port Isabel puts you right on its edge.
- Dolphin-watch cruises: Several boat operators run dolphin and nature cruises out of Port Isabel. Schedules shift with the season, so call ahead or book online.
- Fishing: Pirate’s Landing Fishing Pier, near the lighthouse, runs out into the bay, and you can rent a rod there.
- The causeway: The Queen Isabella Causeway, the second-longest bridge in Texas, makes a scenic drive over the water if you want to see South Padre Island too.
More to do in town
A short walk from the lighthouse, the Port Isabel Historical Museum fills the 1899 Champion Building, a former general store, with two floors of local history. It’s known for one of the largest collections of Mexican-American War artifacts around, from the days when Gen. Zachary Taylor’s army used Point Isabel as a supply base. The museum’s posted hours are Wednesday through Saturday, 10 a.m. to 4 p.m., but call ahead to confirm.
The blocks around the lighthouse have shops and restaurants, and seafood is the obvious order this close to the shrimp boats. Stick around for sunset, when the light hits the bay just right.
If you’re making a longer run down the coast, our guide to Port Aransas in the off-season pairs nicely with a Port Isabel trip.

Some day trips are about packing in as much as you can. This one is about slowing down: a climb, a breeze off the bay and a long look at the water from the top of a lighthouse that’s been standing watch for more than 170 years. Y’all will be glad you made the drive south.
