Open in Google Maps → Big Bend is the least-visited great national park in the Lower 48, and the drive to reach it — five hours of Hill Country, ranchland, and finally raw Chihuahuan desert — is the reason. You earn this one. A 10-day loop from Austin pairs two Texases that could be different countries: the green, wine-soaked Hill Country around Fredericksburg, and the vast, silent desert where the Rio Grande carves canyons a thousand feet deep. And in 2026, there’s a piece of good news that rewrites the plan: the Chisos Basin is staying open after all.
What changed for 2026?
The Chisos Basin’s planned two-year construction closure was cancelled — the mountain heart of the park stays open. If you read that Big Bend’s Chisos was shutting down, that news is out of date.
- The lodge-and-facilities project scheduled to begin May 2026 would have closed the Basin for roughly two years. The Park Service cancelled it in April 2026 over a budget shortfall.
- The lodge, campground, and trails remain open. NPS plans to re-solicit a smaller water-system-only contract later, with no timeline — so give it a glance before you book, but plan on the Basin being open.
What does the trip look like at a glance?
Ten days, about 1,400 miles, two utterly different Texases, best run October through April.
- Launch: Austin, TX (or San Antonio)
- Distance: ~1,400 miles round trip
- Recommended class: Class C 26-28 ft (Chisos Basin advises against over 24 ft)
- All-in budget: $3,500-$4,200 for two people
- Best months: October–April (West Texas summer heat is brutal)
Day-by-day route
Days 1-2: Austin → Fredericksburg wine country
Pick up in Austin, then drive US-290 west into the Hill Country. Base at Fredericksburg for two nights: the National Museum of the Pacific War, a day among the 60-plus wineries (Becker and Grape Creek are the anchors), and the granite dome of Enchanted Rock. Camp: Fredericksburg KOA or Inks Lake State Park.
Day 3: Fredericksburg → Marathon
The long haul west — about 350 miles to Marathon, the last real town before the park. Fill the tank here; it’s the single most important fuel stop of the trip. Camp: Marathon Motel and RV Park (~$35-$50).
Days 4-5: Big Bend — the Chisos Basin
Drive into the Chisos Basin (mind the 24-foot road advisory) and set up in the mountains. Hike the Lost Mine Trail (about 5 miles, the park’s best moderate hike) and the Window Pour-Off, and be out for the sunset through The Window. After dark, look up — this is one of the darkest skies in the country. Camp: Chisos Basin ($16) or Rio Grande Village RV.
Day 6: Santa Elena Canyon
Drive the Ross Maxwell Scenic Drive to the mouth of Santa Elena Canyon, where 1,500-foot walls pinch the Rio Grande to a ribbon. The trail in is short and easy; the scale is not. Camp: Cottonwood ($16, no hookups) or back to the Basin.
Day 7: Rio Grande Village + Boquillas
Walk the riverside Hot Springs trail, then cross at Boquillas — a hand-rowed ferry to a tiny Mexican village (bring your passport). Camp: Rio Grande Village RV (Aramark, ~$36, the park’s only hookups).
Day 8: Big Bend → Sonora
Back north and east to Sonora for the Caverns of Sonora, some of the most decorated cave formations in the country. Camp: Caverns of Sonora RV Park (~$25-$35).
Days 9-10: San Antonio → Austin
Finish through San Antonio — the River Walk, the missions, the Alamo — then the short run up I-35 back to Austin to return the rig.
What does it cost all-in?
About $3,500-$4,200 for two — and the 1,400 miles, not the nightly rig, define the budget. Our July 2026 pull of 3,398 live listings put the national median at $150/night; an Austin-area Class C runs around $165-$185, and Texas fuel sits below the national average, which softens the long drive. Treat these as a research-date snapshot.
| Line item | Amount |
|---|---|
| Class C rental: $165/night × 10 | $1,650 |
| Booking fees + insurance + cleaning | $500–$700 |
| Fuel (1,400 mi @ 8 mpg @ $3.70/gal, TX) | $648 |
| NPS America the Beautiful pass | $80 |
| Campgrounds (NPS $16, private $35–$75) | $300–$450 |
| Caverns of Sonora + wine tastings | $80–$140 |
| Food, propane, dining (2 people) | $700–$1,000 |
| All-in, 10 days | $3,958–$4,748 |

Which RV class fits Big Bend?
A Class C, 26-28 ft — but if you want the Chisos Basin, smaller is better.
| Class | Hill Country + Big Bend fit |
|---|---|
| Class B under 22 ft | Fits everything, including the Chisos Basin road |
| Class C 24-28 ft | The sweet spot, near the Basin’s 24-ft advisory |
| Class C 28-32 ft | Rio Grande Village and Cottonwood; skip the Basin |
| Class A any | Rio Grande Village only — no Chisos |
What goes wrong out here — and how do you handle it?
Big Bend’s hazards are distance, heat, and isolation — all plannable.
- Running low on fuel: fill in Marathon; the park’s pumps are few and far between.
- Summer heat: May-September hits 100°F+ at the river — go in the cool months, or hike dawn and dusk with strong AC.
- Spring break: mid-March fills every campground within days of release — book 6 months out.
- No signal: download offline maps; there’s almost no cell service in the park.
- Cold Basin nights: at 5,400 feet the Chisos can drop cold even when the desert bakes — pack a layer.
Bottom line
The 10-day Hill Country and Big Bend loop is two Texases in one trip — wine and swimming holes, then the emptiest, darkest, most dramatic desert in the state. Base in the Chisos (open again for 2026), fill up in Marathon, go in the cool season, and run a Class C around 26 feet.

Frequently Asked Questions
Is the Chisos Basin open in 2026?
Yes. A major construction project that would have closed the Chisos Basin for about two years — lodge, campground, and access — was scheduled to begin in May 2026, but the National Park Service cancelled it in April 2026 over a budget shortfall. As of now the Basin's lodge, campground, and trails remain open. The Park Service plans to re-solicit a smaller water-system rehabilitation contract later, with no set timeline, so it's worth a quick check before you lock dates.
Can a big RV get to the Chisos Basin campground?
Not comfortably. The road into the Basin is narrow and winding, and the Park Service advises against RVs over 24 feet and trailers over 20 feet, with small campsites on top of that. Reservations are required through Recreation.gov ($16/night). If your rig is larger, base at Rio Grande Village RV Campground down by the river — the park's only full-hookup site, run by Aramark, 25 sites at about $36, though a few spaces can't take rigs 38 feet and up.
How remote is Big Bend, really?
Remote enough that fuel planning matters. Fill up in Marathon before you head south — gas inside the park is limited and there's little between towns. Cell service is near zero across most of the park, so download offline maps before you arrive. It's a three-hour-plus haul from the Hill Country, which is exactly why the night skies are so dark: Big Bend is one of the least light-polluted places in the Lower 48.
What does a Hill Country and Big Bend RV trip cost?
About $3,500-$4,200 all-in for two over ten days: roughly $1,650 for a Class C at $165/night, $500-$700 in fees and insurance, ~$650 in fuel across 1,400 miles (Texas gas runs below the national average), an $80 park pass, $300-$450 in campgrounds, and $700-$1,000 for food, wine tastings, and cavern tours. The long mileage is the trip's defining cost.
When is the best time to go?
October through April. West Texas summers regularly top 100°F at Big Bend's lower elevations — doable only with rock-solid AC and an early-and-late hiking rhythm. Fall and spring are ideal, with the Chisos Basin (5,400 feet) staying cooler and occasionally cold at night. Just steer around mid-March spring break, when every Big Bend campground fills within days of release.
What size RV is best for this trip?
A Class C, 26-28 feet. It handles the long Texas highways, fits the Fredericksburg-area and Rio Grande Village sites, and stays close to the Chisos Basin's 24-foot recommendation if you want the mountain campground. Go bigger and you're committed to Rio Grande Village by the river; go with a sub-22-foot Class B and everything, including the Basin, opens up.
