The Chimneys Trail at Big Bend National Park is a very flat, featureless and exposed hike to a tall and rocky ridge, which is visible in the distance. The trail continues beyond The Chimneys to Old Maverick Road, which runs between Maverick Junction and Santa Elena Canyon, so you could also do this as a one-way walk if you can arrange transportation at both ends.
It’s one of the less-popular trails in Big Bend National Park – I only saw a couple of people – and it’s not a trail I would recommend if you have limited time.
This walk is about the destination, more than the journey: The Chimneys has always been an important landmark, and Indian rock art marks the base of one of the high pinnacles. The petroglyphs are on the southern-most pinnacle, with an unmarked but distinct path leading from the main path up to the base of the rock outcrop.
There’s not much written about the Indian petroglyphs, which vary in age from thousands of years old to some carved in the 1700s and 1800s.
While the walk to The Chimneys is rather uninspiring, the landscape once you get there is interesting. Climbing some of the lower outcrops provides a good view over the desert landscape: to the south is Kit Mountain, and beyond that the Chisos Mountains.
