This hidden gem of a historic public park lies just 5 miles south of tiny Marathon, Texas (population 430). Camp Peña Colorado (today simply known as "Post Park") was the site of a U.S. military encampment around the spring-fed Peña "Colorada" Creek in the late 1800s and now serves as a perfect little picturesque picnic stop on your way out of Big Bend if you're headed back to Austin.
If you're lodging in Marathon or otherwise have the time, the nearly deserted scenic road (southbound Avenue D, aka Post Road, the only one to cross the railroad tracks) out to the park is ideal for running, walking, and biking; bicycles can be rented from the Gage Hotel.
Located in the middle of the Combs Ranch and generously donated to the county by the family in 1935, the land was converted from the ruins of the old cavalry post to a public park by the Works Progress Administration (WPA). Brewster County now maintains the place, which is surrounded by the Los Caballos Novaculite Mountains.
If you're from around these parts, you have likely attended many a public event at Post Park, such as the long-running annual 4th of July Dance, the summer Chili Cook-Off, and the West Fest Cabrito Cook-Off in September. Check the Marathon, Texas tourism page https://www.marathontexas.com/events for details on upcoming events.
The park features several educational historic markers and interpretive nature plaques, a few picnic tables & grills, some covered tables, a couple of cinder-block restrooms, a large concrete slab/dance floor, tons of cottonwood shade trees, and a dammed up portion of the creek that is often home to several species of birds and any other critters seeking a free drink. Wildlife such as deer, javelinas, turkey, jackrabbits, quail, and the occasional fox can be seen in the early morning or around sunset. Fishing is allowed.
A weathered old wooden sign suggests that camping *could* be an option with a permit, but it's not clear how one would obtain such a permit. You might try calling Brewster County offices to check on that.
