On early September mornings, a Texas Observer reporter watched cyclists ride the caliche levee road at Santa Ana National Wildlife Refuge as dawn faded. Some were Border Patrol agents and some were Alamo Police officers. The refuge's own visitor maps showed that road in red to mark it closed. The riders kept going because, as the Observer put it, the road wasn't acting as a construction site at that point.
That scene sums up Alamo's refuge heading into its busiest months. The parts of Santa Ana that run on the refuge's calendar are all on schedule: the tram, the visitor center, and the bird walks. The levee road is different. It runs along the refuge's northern edge, and its status is now set by a lawsuit filed by the irrigation district that supplies Alamo's water. If you plan to bike Santa Ana this winter or bring guests on the tram, the date to watch is October 15, not a day in November.
What Shows Up on Schedule in November
The tram is the clearest sign of the refuge's season. The U.S. Fish & Wildlife Service tours page says plainly that "The Interpretive Tram Tours will be back in November," with departures at 11 a.m. and 2 p.m. through March. FWS pages list different operating days. The tours page says Tuesday through Saturday, while another FWS listing says Wednesday through Saturday. Before you plan a tram morning around visiting relatives, call the refuge office at 956-784-7500 to confirm.
The visitor center also runs on a seasonal schedule. It is open November through April, Tuesday through Saturday, 9 a.m. to 4 p.m. The Friends of the Wildlife Corridor Nature Shop is there too, with field guides and t-shirts, along with the auditorium film and the exhibits that help first-time guests get their bearings.
Some things don't change by season at all:
| Feature | What FWS lists |
|---|---|
| Trail hours | Seven days a week, sunrise to sunset |
| Entry | $5 parking fee per vehicle |
| Free days | First Sunday of every month |
| Bird walk | First Saturday of the month, 8:30 a.m. |
| Trail system | Over 14 miles of trails, 7 miles of biking routes |
| Getting there | Highway 83 to Alamo, south on FM 907 for seven miles, left on Old Military Highway for about a quarter mile |
The calendar works out well this year. November 1, 2026 is a Sunday, so the free first-Sunday entry lands on the first day of the tram month. November 7 is the first Saturday, so the monthly bird walk comes in the same week.
The Short Walks Are Unaffected
The refuge's own suggestions for a short visit stay well away from the construction. FWS recommends the Malachite Trail if you have 15 minutes and the Tower and Chachalaca trails if you have an hour. The research turned up no reported closures or reroutes for the inner trails, the auto-tour loop, the Observation Tower, the Canopy Bridge, or the tram route. The Observer's reporter climbed the tower in September.
The tower view has changed, though. From the top, the newly built wall sections are visible on the north side of the 360-degree view. According to the Observer, contractors put up two short sections on the refuge's western edge in June and July, ending a dozen or so yards from wall built years earlier. Your guests will see them if they climb the tower.
How the Levee Road Became the Exception
The closure started with a short refuge Facebook post in June, reported by The Monitor:
"The levee is expected to be closed to bicycle and pedestrian traffic for the remainder of the summer while construction is ongoing. During this period, bicyclists should use Bobcat Trail as a detour route. We will advise when it has reopened for public access."
The work is part of the U.S. Customs and Border Protection "Rio Grande Valley 4 Project," a stretch of nearly 3 miles along Levee Road across the top of the refuge. KRGV reported CBP's planned timeline as starting in July 2026 and finishing in September 2027. On that timeline, construction would run through this entire November-to-March tram season and on through the summer of 2027.
Summer ended without the refuge announcing a reopening. As of early October, our research found neither a reopening notice nor a formal extension. The September reporting describes a road the refuge still counts as closed, even though people are riding it. Until the refuge says otherwise, its official detour is still Bobcat Trail. FWS describes it as the refuge's caliche bike trail. It cuts through the auto-tour loop to make a four-mile ride.
The Water District in the Middle
The construction pause didn't come from the refuge or from CBP. It came from Hidalgo County Irrigation District No. 2. The district sued the contractors, Spencer Construction and Royal Concrete, in July. It alleged they were building on district property, dumping debris into the irrigation canal next to the levee, and trespassing. According to the lawsuit, that canal is the only water source for Pharr, San Juan, and Alamo.
ValleyCentral reported that the district alleges about 800 feet of wall was built on its property. The contractor's owner testified that the work involves digging a trench, pouring concrete, and inserting panels, starting on a segment near Santa Ana on July 13. The case was later moved to federal court, and Judge Arthur Jones in McAllen ordered construction paused until October 15. On September 14, the district added the United States as a defendant and asked for a permanent injunction.
As of today, October 7, the CourtListener docket shows filings from late September, an October 6 clerk's notice, and an October 7 statement of case review by the United States. It shows no ruling. The docket also warns that its data may not be up to date.
That leaves a few possibilities for the weeks before the tram returns. The pause could expire and construction could resume. The court could extend the pause. The judge could rule on the injunction request. Any of these would affect how the levee road is used, but none of them would change the tram schedule.
What Changes Further Out
The longer view is in the Observer's reporting. Surveyors have staked the levee road from east to west to mark where 30-foot steel bollards on a concrete base would go. The Observer reports that once the wall is finished, visitors will see it before reaching the trailheads, and those trailheads will be reached through a locked gate. The paper also notes the wall won't run through the center of the refuge. For a refuge that has offered sunrise-to-sunset trail access seven days a week, a locked gate is the change that would most directly affect how locals use it. No gate hours or procedures have been published.
Dates on the Calendar Between Now and the Tram
- October 15, Thursday. The court-ordered construction pause is set to end unless the court acts.
- October 17, Saturday, 8 a.m. to noon. The 32nd Annual Rio Reforestation plants native habitat at the refuge system's Milagro Tract in Pharr, not at Santa Ana itself.
- October 30, Friday, 6 to 9 p.m. The City of Alamo's All Hallows' Eve, with trunk-or-treat, vendors, and performers at Alamo Downtown Central Park, 800 E. Main Street.
- November 1, Sunday. Free entry day at Santa Ana, the first of the season.
- November 7, Saturday, 8:30 a.m. The monthly bird walk.
The refuge said in June that it "will advise when it has reopened for public access," so check the refuge's own posts and the office line at 956-784-7500 for the levee road's status. Santa Ana is at 3325 Green Jay Road. The trails open at sunrise.
Hacienda Properties RGV has worked across Alamo, Pharr, and San Juan since 1986, and the refuge is part of what makes this corner of the Valley home. We'll keep following the levee road and the season ahead. If you'd like to talk about the area around Santa Ana, in English or Spanish, please contact us.
