Phil Hardberger Park is a 330-acre natural-area park in north-central San Antonio with 8 miles of trails, including the Water Loop and Geology Trails (2.5 miles combined), the Oak and Savanna Loop (5 miles), and access to the Salado Creek Greenway. The park's master plan reserves 75 percent of its acreage — roughly 247 acres — in a permanently managed natural state, giving it a genuinely wild character unusual for a park surrounded by dense suburbia. Its centerpiece is the Robert L.B. Tobin Land Bridge, which opened in December 2020 across busy Wurzbach Parkway: at 150 feet wide, it is the largest urban wildlife crossing in the United States, and trail cameras have already documented deer, coyotes, rabbits, and opossums using the crossing. The Urban Ecology Center on the park's west side offers educational programming and overlooks the creek corridor. Both the east and west halves of the park have their own dog parks and playscapes. The park is free, open sunrise to sunset, and located near the intersection of NW Military Highway and Wurzbach Parkway. Early mornings in spring bring good birding in the oak savanna sections.
