Houston-Pasadena-The Woodlands, TX · 17 units within 8 hours

National Park System units within a drive of Houston

One National Park System unit sits within an estimated two hours of Houston, two between two and four hours, and 14 between four and eight. The closest is Big Thicket National Preserve, about 1.7 hours by road from the metro's Census centroid. The metro is the Houston area as the Census Bureau defines it, home to 7,796,182 people in the 2024 estimates.

Each drive time is an estimate made from the straight-line distance between the metro's Census centroid and the unit's listed coordinates, multiplied by 1.25 for roads and divided by 55 mph, so a real trip will often take longer.
