Hear the guide

It knows which hike is worth the climb.

This is the real narration from Parkwolf’s Big Bend tour. It starts on its own as you approach each stop, so you never tap or read while driving.

“…one of the best reward-for-effort hikes in all of Big Bend… Just a heads up, the parking lot here is famously small, so finding a spot can be a challenge.”

The Ross Maxwell Scenic Drive, narrated

The tips that save your Big Bend day.

Three real lines from the narration, each with the app’s tip for that stop, in the order you’ll reach them driving the Ross Maxwell Scenic Drive to Santa Elena Canyon.

    “This is the spot for that classic, wide-open Big Bend panorama, looking across the desert all the way to Santa Elena Canyon in the distance.”

“The local wildlife, park site and geography commentary were informative and timely. The fact that it works without cell service is a real plus, as Big Bend has very spotty coverage.”
★★★★★ Korndog101 · Big Bend, January 2026
“This was a life saver in Big Bend. Can’t wait to use it for our next NP trip.”
★★★★★ HeatherFittz · Big Bend, April 2024
“We drove the entire length of the Going-to-the-Sun Road with no cell service for the majority and this app gave us information as we approached areas and even during our hike that was educational and helpful.”
★★★★★ mclvt2011 · Glacier, July 2026
“The app was excellent providing a driving tour guide. We stopped in places we would have normally drove right past.”

Questions before you go

How does the self-guided Big Bend tour work?

Open Parkwolf, tap Start Tour Guide and drive. Your phone’s GPS triggers each story as you approach an overlook, trailhead, pullout or hidden spot. There’s no set route, so take any road in any order.

Will it help me plan my Big Bend itinerary?

Yes. Every stop has the app’s tips on water, heat, timing and parking, and every trail lists its distance, climb and time, so you can plan each day before you go. Then the guide narrates it as you drive.

Does it work without cell service?

Yes. Download Big Bend before you go and the map, the narration and every tip work offline, even where your phone shows no bars.

What does it cover?

The Ross Maxwell Scenic Drive to Castolon and Santa Elena Canyon, the Chisos Basin Road, Panther Junction, the road to Rio Grande Village and Boquillas Canyon, Persimmon Gap and the Fossil Discovery Exhibit, plus backcountry roads like Old Ore Road and River Road: 124 stories in all.

How much does it cost?

Parkwolf is free to download. The Tour Guide is part of Parkwolf PRO, which starts with a free trial, and one subscription covers everyone listening in your car.

Does it work with CarPlay or Android?

Both. Parkwolf works with Apple CarPlay, and it’s available on Google Play for Android.

Can I use it in other parks?

Yes. The same guide covers 100+ national parks, state parks and scenic drives, from Yellowstone to the Blue Ridge Parkway.
