At 600 Sunset Drive, Quinta Mazatlán's parking note sits beside the directions. The free parking outside the gates is limited "due to the expansion project opening in the Fall of 2026," and visitors are asked to carpool or use a rideshare and to watch for pedestrians, especially children and school groups. Past the gates, the historic home, gardens, walking trails and art installations are all still there.
The fenced construction next door is the Center for Urban Ecology, a 15-acre addition built in partnership with UTRGV. Quinta's homepage lists it as under construction, with the grand opening planned for "Fall of 2026" and no day attached. The schedule has moved before. When the City of McAllen held the topping-off ceremony in February 2025, it called the $76 million center 60% complete and expected it to be finished by spring 2026.
The new building is designed around classrooms, an event hall and evening use, and Quinta's fall programming already runs on that schedule. If you've known Quinta mainly as a weekday morning walk in the woods, the calendar between now and December gives you an early look at the place it's turning into.
The new front door starts in the parking area
The first change is how you'll arrive. According to the project page from builder SpawGlass, updated in July 2026, an arched-steel walk-through tunnel will run from the parking area to the main entrance of the CUE. Nearby is the center's landmark, "Wings Over the Valley," a three-part canopy made of corten steel.
That changes the sequence of a visit. Today you park, pass through the gates, and you're on the trails or at the historic house. Once the CUE opens, you'll start under steel, walk through a tunnel and reach a building before the woods. Quinta's directions page doesn't say whether vehicle access or street entrances will change. Until the center opens, the practical takeaway is the one on that page: parking is tight, so ride together if you can.
What the 15 acres add
The SpawGlass description is the most recent detailed inventory, and it lists two kinds of space.
Indoors, a two-level building of 15,150 square feet holds:
- indoor classrooms
- administrative offices
- a gift shop
- the Palm Room, a 250-seat ballroom with a catering kitchen
Outdoors, the plans include:
- a stream modeled on the Rio Grande
- sensory gardens
- natural playscapes
- shaded picnic palapas
- habitat restoration areas
- educational signage on native plants and conservation of native flora
The city's 2025 announcement adds interactive exhibits, hands-on learning, research opportunities and internships, along with courses tied to UTRGV. The contractor's list confirms the classrooms and signage but doesn't name individual exhibit galleries, so expect to learn the exhibit details on opening day.
A building made for classes and evenings
The two lists point the same way. A 250-seat room with its own catering kitchen is built for dinners, lectures and gatherings, and none of those depend on daylight. Classrooms are built for scheduled sessions. Picnic palapas and playscapes are built for families who stay a while. All of these put Quinta's programs at the center, with the trails around them.
Quinta already runs on that model, one day a week. Under the hours on Quinta's admission page, the grounds are open 8 a.m. to 5 p.m. on Tuesday, Wednesday, Friday and Saturday and closed Sunday and Monday. On Thursday they stay open past 5. That late night is when the Thursday Speaker Series meets, every week from 6 to 7 p.m., free with general admission. October's named speaker was Carlos García Patlán on community forestry. Once the Palm Room opens, the evening lecture becomes the core use of the building. For now, it's a weekly hour in an older setting.
The city is also planning beyond this phase. In January 2026, The Monitor reported that McAllen proposed buying another 3.96 acres northeast of 10th Street and Bales Road for a further Quinta expansion. It also reported that Phase II funding would help widen Bales Road from 10th Street to Second Street. That purchase is a proposal, not a finished project.
The fall calendar, read as a preview
Quinta's event calendar and workshop page already line up with the new building's three uses. Some programs teach, some draw crowds in the evening, and some are built around a season. Here's what's on the schedule from Halloween through early December:
| Date | Program | Time | What it is |
|---|---|---|---|
| Sat., Oct. 31 | Urban Forest Birding | 8:30–10 a.m. | Fall migration heading south and the return of winter birds |
| Sat., Oct. 31 | STEM Stops | 11 a.m.–2 p.m. | Owls and what they eat |
| Every Thursday | Thursday Speaker Series | 6–7 p.m. | Free with general admission |
| November | Re-Fest | Month-long | Event and festival, dates by month only |
| Sat., Nov. 21 | All About Milkweeds | 9:30–11:30 a.m. | $10 workshop, registration required |
| Sat., Dec. 5 | How to Create a Backyard Bird Paradise | 9:30–11:30 a.m. | $10 workshop, registration required |
| December | Holiday Concerts in the Park | Four concerts | Specific dates not yet listed |
The two Saturday workshops are for adults and older youth. Both focus on what to plant in a Valley backyard, so you can take what you learn at Quinta home to your own yard. The October calendar also lists recurring sessions: Walk With A Naturalist on Wednesday mornings from 9 to 10, Tai Chi on Saturday mornings, and Rooted Yoga on a Wednesday evening.
Evening events already draw a crowd. KRGV covered Boo in the Woods ahead of its Oct. 23–24 nights, which ran from 6 to 10 p.m. with a quarter-mile Sticks & Bones Trail, a glowing pumpkin tunnel, a spider maze, live music and food vendors. December's four Holiday Concerts in the Park will bring another crowd to the grounds. Large gatherings like these are the kind of event the Palm Room and the picnic palapas were designed to hold.
What a visit costs while the work continues
The new center has no posted admission price of its own. These are the current rates for Quinta as a whole:
- Free: members and children 2 and under
- $2: ages 3 to 12 and visitors 65 and older
- $3: ages 13 to 64
Annual memberships are $20 for seniors, $30 for individuals and $50 for a family of two adults and their children, and all include free general admission. If you're going to more than a handful of Thursday talks or Saturday programs this season, a family membership covers the cost of a few visits. The $10 workshops are a separate charge.
Before a Thursday visit, check the closing time. Quinta's homepage lists Thursday hours as 8 a.m. to 7 p.m., while the admission page says 8 a.m. to dark. In late fall, dark comes earlier than 7, so call ahead if you're planning to walk the trails after the speaker session.
If you'd like more room to spread out while Quinta's lot is squeezed, McAllen's other newer outdoor spot is Camp McAllen at 8621 N. 23rd St. The city parks department lists it as open Tuesday through Sunday from 8 a.m. to 8 p.m., with kayak and fishing docks, a shaded gazebo and trails.
When the Center for Urban Ecology opens, Quinta will still have its historic house and trails, plus a building designed for the kinds of programs already on this fall's calendar. If you're watching for the opening date or have friends coming to visit this season, Gallo Realty is happy to share what we know about McAllen's newest public spaces. Let's Connect.
