The Big Bend Loop, Mile by Mile
Three hundred and forty miles, four legs, two gas stations you cannot skip. The version of this drive I wish somebody had written down for me in 2019.

The Short Answer
Drive it counterclockwise over three days, starting in Marathon and finishing in Marfa. If you only have two days, cut leg three. The essentials:
- Marathon — last full-service fuel for seventy miles, and a good bed.
- Chisos Mountains Lodge, in the basin — book it a year out or camp instead.
- FM 170, Terlingua to Presidio — the best road in Texas.
- Marfa — the only place on the loop with a real dinner reservation.
The first time I drove to Big Bend I did it in one push from San Antonio, arrived at dusk with a quarter tank, and learned that the gas station at Study Butte closes earlier than you would like. That trip taught me more about this loop than the ten since, all of which have been better planned and less interesting to talk about.
What follows is the route as I now drive it: counterclockwise from Marathon, four legs, three nights, roughly 340 miles of pavement. Nothing here requires four-wheel drive. All of it requires paying attention to fuel, light and heat, in that order.

How We Chose Them
I have driven this loop eleven times since 2019, in a truck, a rented sedan and once, unwisely, in February. The route below is built around four constraints:
- Fuel. There are two reliable stations on the whole loop and a third that is closed as often as it is open. Every leg here starts with a full tank.
- Light. The Chisos face west and Santa Elena faces east, so the order of the legs is set by when each one looks like anything.
- Heat. Everything below 3,000 feet is unwalkable from May to September after about ten in the morning. Legs are timed around that, not around mileage.
- Beds. Four places to sleep on the loop take reservations, and three of them book six months to a year ahead. The route accounts for what you can actually get.
Mileage was logged on the odometer, not pulled from a mapping app. Fuel prices, lodge availability and road conditions were confirmed with the Panther Junction visitor center and the Presidio County sheriff's office in July 2026. We pay for our own gas.
The Loop, Leg by Leg
No. 1: Marathon to Panther Junction
Seventy miles of empty two-lane running due south off US-90, with the Chisos appearing on the horizon somewhere around mile fifty.

Persimmon Gap is the north entrance, and the first forty miles look like this. National Park Service Digital Image Archives / Wikimedia Commons (Public domain) Marathon is a town of about four hundred people on US-90 with a 1927 hotel, one good restaurant, and the last full-service fuel before the park. Fill the tank here even if the gauge says you are fine. Then turn south on US-385 and drive seventy miles without passing a single business.
The road is good, the traffic is nonexistent before nine, and the range is unfenced, which means cattle stand in the lane at dusk with total confidence. The Persimmon Gap visitor center has a small fossil exhibit that is worth ten minutes, mostly for the mosasaur skull.
Heads up:this is open range with no services for seventy miles. Fuel up in Marathon, watch for cattle and javelina at dusk, and expect no cell signal after mile 12.

No. 2: The Chisos Basin Road
Six miles and 1,700 feet of climbing into a bowl surrounded on all sides by mountains, ending at the only lodge inside the park.
The climb into the Chisos BasinSix miles and 1,700 feet up to the only lodge inside the park. From Panther Junction the Basin Road climbs six miles and 1,700 feet into a bowl ringed by mountains, and the temperature drops about a degree for every two hundred feet you gain. In August that is the difference between miserable and pleasant. The grade hits 15 percent and the switchbacks are tight enough that the park bans trailers over twenty feet.
Chisos Mountains Lodge is the only hotel inside the park and books close to a year out. If you cannot get a room, the basin campground takes reservations on the same system and is easier, and the walk to the Window View overlook is five minutes from either.
Best for:the last hour of daylight, when the sun drops through the Window gap.

No. 3: Ross Maxwell to Santa Elena Canyon
Thirty miles southwest past Mule Ears and Tuff Canyon to a 1,500-foot limestone gash with the Rio Grande running out of it.
The mouth of Santa Elena CanyonFifteen hundred feet of limestone with the Rio Grande running out of it. Ross Maxwell Scenic Drive runs thirty miles southwest from the main park road toward the river, past Sotol Vista and Mule Ears and down through Tuff Canyon to the old Castolon store. Give it two hours with stops. Give it more if the light is good.
At the end, Santa Elena Canyon: a 1,500-foot limestone wall split by the Rio Grande, with Mexico on one side and Texas on the other and about sixty feet of water between them. The trail is 1.7 miles round trip with one steep set of switchbacks at the start. Do it before nine.
Heads up:Terlingua Creek at the Santa Elena trailhead runs knee deep after rain and has turned people back. Ask at Castolon before committing to the drive.

- 1.7 miles round trip, one steep section
- Terlingua Creek, sometimes knee deep
- Before 9 a.m., east-facing

- The single best short hike in the park
- Castolon store sells cold drinks and ice
- Pullouts at Sotol Vista and Mule Ears are worth the stops
Cons
- Terlingua Creek can be impassable after rain
- Nowhere near shade between 10 a.m. and 5 p.m.
No. 4: FM 170, Terlingua to Presidio
Fifty miles of pavement pinned between the Rio Grande and the Bofecillos Mountains, including a 15 percent grade locals call the Big Hill.

FM 170 starts here and runs the river all the way to Lajitas. / Wikimedia Commons (Public domain) Leave the park at Study Butte, top off the tank, and turn west on FM 170. For the next fifty miles the road runs between the river and the Bofecillos Mountains, climbing over the Big Hill at a grade steep enough that trucks downshift twice, then dropping back to the water. Texas Monthly has called it the best drive in the state. They are right, and it is not an argument I have ever heard anyone lose.
There are stone teepee shelters at intervals, built as roadside picnic stops, and they are the right place to eat lunch. Presidio at the far end has fuel and not much else. Keep going to Marfa, sixty miles north on US-67, and eat somewhere with a tablecloth.
Know before you go:there is a Border Patrol checkpoint north of Presidio. Have identification within reach and expect a two-minute stop.
How it scored- 5.0 out of 5
- 4.7 out of 5
- 3.0 out of 5
- 5.0 out of 5
Key facts- 50 miles
- 75 minutes, longer with stops
- 15 percent at the Big Hill
- Study Butte, then Presidio
- None
- Last two hours before sunset
Pros
- Widely considered the best drive in Texas
- Teepee shelters make good free lunch stops
- Barton Warnock center at the east end is worth an hour
Cons
- Steep grades and blind curves, no guardrail in places
- Border Patrol checkpoint on the far end, have ID ready
The mistake everybody makes out here is treating distance like time. Seventy miles is ninety minutes, and there is nothing in between to change your mind.

Frequently Asked Questions
How many days do you need for the Big Bend loop?
Three is right. Two is possible if you cut the Ross Maxwell leg. One day means you will spend most of it in the car and see the park through a windshield, which is a long way to drive for that.
Where do you get gas in Big Bend?
Marathon, Panther Junction inside the park, Study Butte at the west entrance, and Presidio. That is the whole list. Fill up whenever you pass one, whether or not you think you need to.
Is there cell service in Big Bend National Park?
Very little. There is intermittent service around Panther Junction and in parts of the Chisos Basin, and effectively none on US-385, the Ross Maxwell drive, or FM 170. Download offline maps before you leave Marathon.
When is the best time to drive the Big Bend loop?
November through March. Daytime highs sit in the sixties and seventies and the light is better. March spring break fills every bed in the region, so aim for November, early December or late January.
Do you need four-wheel drive for the Big Bend loop?
Not for this route. Everything described here is paved, including FM 170. Four-wheel drive matters only if you leave the pavement for Old Ore Road, River Road inside the park, or the interior of Big Bend Ranch State Park.
Where should you stay on the Big Bend loop?
Chisos Mountains Lodge inside the park if you can get it, which means booking close to a year out. Otherwise Terlingua and Study Butte have the most options, Marathon has the best single hotel, and Marfa is the right last night.
