Sunnyside waited a long time for this. Nearly 50 years passed without a new public greenspace in one of Houston's oldest historically Black communities, a neighborhood that deserved what every Houston family deserves: somewhere close to home to walk, breathe, gather, and watch the city from a different angle.

In late May 2026, that wait ended. Hill at Sims opened its gates to South Central Houston, and what it brought is worth describing carefully.

What the Park Actually Offers

The 100-acre park sits along Sims Bayou and was built inside a working stormwater detention basin owned by the Harris County Flood Control District. The engineering challenge was real: design a regional park that still performs its flood-management function for the surrounding community. The result is a landscape that does both, layering nearly 5 miles of paved and dirt hike-and-bike trails over the basin's working infrastructure.

Beyond the trails, the park includes bayou crossings and overlooks, outdoor classrooms, water access points, restored native planting, and large-scale murals created for the community. A hilltop pavilion sits at the park's high point with expansive views of Downtown Houston, the Uptown skyline, and the Texas Medical Center. That view alone tells you something important: Sunnyside is not on the edge of this city. It is at the heart of it.

More than 670 native trees from Texas Parks and Wildlife and Trees for Houston were planted across the site, a detail that signals this park was built to grow with the neighborhood for decades, not just for the ribbon-cutting.

For Houston families, the specific mix of features at Hill at Sims is worth knowing before you head out. The paved sections of the trail are stroller-accessible and bikeable, while the dirt paths offer a different kind of experience for runners and walkers who want to feel closer to the bayou. The bayou crossings are the kind of small-scale infrastructure that changes how a family can move through a space, allowing circuit routes rather than out-and-back trips. The outdoor classrooms are positioned near the water access points, making the park a natural destination for school groups and families who want to make an afternoon visit into something educational.

How This Park Came Together

The nearly $30 million project was led by the Office of Commissioner Rodney Ellis and Houston Parks Board, with design by SWA Group and a multidisciplinary team. Funding came from two sources: nearly $22 million from public funds through Commissioner Ellis's office, and $8 million privately from The Brown Foundation. The public grand opening celebration was held on Saturday, May 30.

That funding structure is worth understanding because it explains something about how large park projects actually happen in Houston. A community like Sunnyside cannot rely on a single source of government funding to move a $30 million project from concept to open gates. The combination of public infrastructure investment from Commissioner Ellis's office and private philanthropic commitment from The Brown Foundation is the model that made this work.

The design team, led by SWA Group, also had to solve a genuine engineering problem. The stormwater detention basin the park is built on is still a functioning piece of flood control infrastructure for the surrounding neighborhood. Hill at Sims does not replace that function. It adds to it, which is a different and harder design challenge than building a park on vacant land.

What It Means for Houston Families This Summer

For parents looking for an outdoor destination that is accessible without a long drive, Hill at Sims is a real option on the south side of Houston. The park's location in Sunnyside, at Sims Bayou, puts it within reach of neighborhoods that have not always had easy access to well-maintained trail systems. The 610 Loop is not far. The Medical Center is visible from the hilltop.

Back-to-school season is almost here, and the weeks remaining in summer are a natural time to explore what Hill at Sims looks like in the long afternoon light before September shortens the days. The open question is how the park's programming develops over the next year. The outdoor classrooms and murals signal an intention to make the park a cultural and educational space, not just a recreational one. Sunnyside has a deep history in Houston, and a park that takes that history seriously in its public art and educational programming would be something more than a place to walk. It would be a place that reflects the neighborhood back to itself.

The summer heat is real in South Central Houston, and early morning or late afternoon visits will be the most comfortable until the season turns. The bayou access points offer some shade, and the trail system is wide enough in most sections to catch a breeze off the water.
