2026 update (checked October 21, 2026): The Lost Mine Trail is open. The two-year Chisos Basin closure that was planned to start in May 2026 was cancelled, so you may see out-of-date warnings online. The Park Service says the park “remains fully open to visitors.” The Chisos Mountains Lodge restaurant is currently closed, but a food truck operates outside the lodge, and the Chisos Basin Visitor Center is open. Check the park’s alerts before you go.
The Lost Mine Trail in Big Bend National Park is the hike that surprises people. Most visitors picture Big Bend as hot, flat desert. Then they drive up into the Chisos Mountains, step onto this trail, and find themselves in cool pine and oak woods, climbing toward a rocky ridge with views straight into Mexico.
It’s 4.8 miles round trip with about 1,100 feet of climbing, and most people finish in about three hours. Even if you only hike the first mile to the saddle, you get one of the best views in the park.
This guide covers everything: the route step by step, the views, difficulty, parking (the lot is tiny), the best time to go, wildlife, what to bring, and how Lost Mine compares to the Window Trail.

Where Is the Lost Mine Trail?
The trail is in the Chisos Mountains, the only mountain range found entirely inside a U.S. national park. The trailhead sits on Chisos Basin Road, about 5 miles from the main park road at Panther Pass, the high point of the road just before it drops into the Chisos Basin.
Any regular car can make the drive on the paved road. It’s steep and curvy, though, and the park doesn’t recommend trailers over 20 feet or RVs over 24 feet on Chisos Basin Road.
Because you start in the mountains, the air is often 10 to 20 degrees cooler than the desert floor. That’s a big reason this trail is so popular.
About the name: Legend says Spanish settlers ran a rich silver mine somewhere on Casa Grande, the big flat-topped peak beside the trail, and hid its entrance so well that it was never found again. Nobody has ever proven it existed, but the name stuck.
Lost Mine Trail Step by Step
1. Start in the woods
The trail leaves the small parking lot and climbs gently through a forest of juniper, oak, and pinyon pine. Look for Texas madrone, a tree with smooth, reddish bark that peels like paper.
The first part is a steady, easy uphill. Use it to warm up and find a comfortable pace.
2. Reach the saddle (about 1 mile)
After about a mile, you reach a saddle, a low point on the ridge with a wide-open view. Straight ahead is Casa Grande, and below you is Juniper Canyon stretching south.
This is a great place to turn around if you’re short on time, hiking with young kids, or just want a big view for little effort. That makes a 2-mile round trip.
3. Climb the switchbacks
Past the saddle, the trail gets harder. The second half climbs a series of switchbacks and rock steps up the mountain. It’s steeper and more exposed to the sun, so slow down and take breaks.
The views keep getting better as you climb. Look back often.
4. Walk out onto the ridge
Near the top, the trail levels out and follows a rocky ridge. The trees thin out, and the views open up in every direction.
5. Enjoy the view from the end
The trail ends on an open, rocky high point. On a clear day you can see:
- Pine Canyon, a deep, wooded canyon right below you
- Casa Grande and the high peaks of the Chisos
- The Sierra del Carmen in Mexico, with its long pink-and-gray cliffs
- Endless desert stretching to the horizon
There are steep drop-offs near the edges, so find a safe spot to sit, have a snack, and take it all in.
6. Head back down
You return the same way. The descent is faster but rocky, and the steps can be slippery with loose gravel. Watch your footing, especially on tired legs. Trekking poles help.
How Hard Is the Lost Mine Trail?
Lost Mine Trail is moderate. It’s not technical, but it’s uphill almost the whole way out.
| Section | Difficulty | What to expect |
|---|---|---|
| Trailhead to saddle (1 mile) | Easy to moderate | Gentle, steady climb through the woods |
| Saddle to ridge (1.4 miles) | Moderate to hard | Steeper switchbacks, rock steps, more sun |
| Ridge and viewpoint | Moderate | Rocky ground, drop-offs near the edges |
| Return trip | Moderate | Downhill on rocky, sometimes loose ground |
What makes it harder:
- Steady climbing. You gain about 1,100 feet, mostly in the second half.
- Elevation. You start around 5,700 feet, so you may breathe harder than usual.
- Sun. The upper trail has little shade.
Good for beginners? Yes, for beginners who walk regularly. Go slow, rest often, and remember you can always turn around at the saddle. For more tips, see our hiking for beginners guide.
Scared of heights? The trail itself isn’t exposed, but the viewpoint at the end has steep drop-offs. Stay back from the edges, and you’ll be fine.
How Long Does It Take?
| Plan | Typical time |
|---|---|
| Saddle only (2 miles round trip) | 1–1.5 hours |
| Full trail at a steady pace | 2.5–3.5 hours |
| Full trail with lots of photo stops | 3.5–4 hours |
The Park Service says the average is about three hours for the full hike.
Lost Mine Trail Parking
This is the biggest challenge of the whole hike.
- The trailhead lot holds only about 15 cars.
- From November through April, it regularly fills between 8 and 9 a.m.
- Don’t park along the road. It’s not allowed, and the road is narrow and curvy.
How to get a spot:
- Arrive by sunrise in the busy season.
- Try in the afternoon when early hikers leave.
- Have a backup plan, like the Window Trail or the Chisos Basin Loop from the Basin parking lot. The Park Service suggests trying another trail and coming back later if the lot is full.
Best Time to Hike Lost Mine Trail
| Season | Weather | Our take |
|---|---|---|
| Fall (October–November) | Mild days, clear skies | One of the best times; lot fills early |
| Winter (December–February) | Cool days, cold mornings, possible ice or snow | Great, but bring layers |
| Spring (March–April) | Warm, often windy, very busy | Beautiful; start at sunrise for parking |
| Late spring and summer (May–September) | Hot in the desert, cooler in the Chisos, afternoon storms | Hike early; turn back if lightning threatens |
Best months: October, November, February, and March are usually the most comfortable.
Sunrise or sunset? Sunrise is the best choice for most people. It’s cooler, the parking is easier, and the morning light on the mountains is beautiful. Sunset is gorgeous too, but you’ll be coming down rocky steps in the dark, so bring a headlamp and only do it if you’re comfortable hiking at night.
Fees and Permits
- Day-hike permit: Not needed.
- Entrance fee: $30 per private vehicle, $25 per motorcycle, or $15 per person on foot or bike, all valid for 7 days.
- Big Bend annual pass: $55.
- Payment: Cards only. The park doesn’t accept cash.
- America the Beautiful passes are accepted.
What to Bring
- Water: At least 1 to 2 liters per person, and more on warm days. There’s no water on the trail.
- Salty snacks
- Hiking shoes with good grip for rocky steps
- Sun hat, sunglasses, and sunscreen
- A light jacket for cool mornings and windy ridges
- Trekking poles for the descent
- An offline map, since cell service is spotty
- A headlamp if you’re starting early or finishing late
- A small first-aid kit
- A bag to pack out toilet paper. There are no toilets.
Wildlife on the Lost Mine Trail
The Chisos Mountains are home to animals you won’t see in the desert below, including the small Carmen Mountains white-tailed deer, noisy blue Mexican jays, and lots of lizards.
Black bears and mountain lions also live here. Sightings are rare, but the Park Service asks you to:
- Keep kids close. Don’t let them run ahead.
- Never run from a mountain lion. Stand tall, make yourself look big, and back away slowly.
- Never feed or approach bears. Keep your food with you.
- Keep your music low or off so you can hear what’s around you.
Is Lost Mine Trail Safe for Solo Hikers?
Yes, for prepared hikers. It’s a popular, well-marked trail, so you’ll usually see other people, especially in the morning. But cell service is spotty, and an injury, a bad fall, or heat trouble is more serious when you’re alone.
- Tell someone your plan and when you expect to be back.
- Download an offline map before you lose signal.
- Carry extra water and a small first-aid kit.
- Skip the hike in storms or icy conditions.
If you’re new to mountain or desert hiking, bring a friend for your first trip.
Is Lost Mine Trail Good for Kids?
Yes, especially the first mile. The hike to the saddle is a great family outing with a big view. Older kids who like to climb often do the whole trail.
Keep kids close at all times because of wildlife, and hold hands near the drop-offs at the end.
Lost Mine Trail vs. Window Trail
These are the two most popular hikes in the Chisos.
| Feature | Lost Mine Trail | Window Trail |
|---|---|---|
| Distance | 4.8 miles round trip | About 5.6 miles round trip from the Basin |
| Elevation | About 1,100 feet, uphill first | Downhill first, uphill on the way back |
| Difficulty | Moderate | Moderate |
| Highlight | Big mountain views into Mexico | A narrow rock “window” overlooking the desert |
| Parking | Tiny lot, fills early | Chisos Basin lots, more spaces |
| Best for | Panoramic views | Canyon scenery and a pour-off |
Can’t decide? Do both. Lost Mine in the morning, the Window Trail in the afternoon (or at sunset from the Basin).
Lost Mine Trail vs. Other Big Bend National Park Hikes
If you’re planning a few days in Big Bend National Park, TX, here’s how Lost Mine compares with other popular hikes:
| Trail | Distance | Difficulty | Highlight |
|---|---|---|---|
| Lost Mine Trail | 4.8 mi | Moderate | Chisos Mountain views into Mexico |
| Grapevine Hills | 2.2 mi | Easy, then a short scramble | Balanced Rock |
| Santa Elena Canyon | 1.6 mi | Easy to moderate | Rio Grande canyon walls |
| Window Trail | About 5.6 mi | Moderate | Pour-off “window” over the desert |
| Emory Peak | About 10.5 mi | Strenuous | Highest point in the park |
Bird lovers: the Chisos woodlands are also the main U.S. home of the Colima warbler, which nests here in spring and summer. Listen for it in the oaks along the lower trail.
Where to Stay
- Chisos Mountains Lodge: The only lodge in the park, in the Chisos Basin, a few minutes from the trailhead. The restaurant is closed for now, but a food truck operates outside the main lodge building.
- Chisos Basin Campground: Also in the Basin, so you’re close to the trailhead for a sunrise start. Book ahead in busy seasons.
- Terlingua and Study Butte: Just outside the park’s west entrance, with cabins, rentals, motels, and restaurants. It’s about 45 minutes or more to the trailhead, so leave early.
Practical Tips
- Start early. It’s the key to parking, cooler temperatures, and a quieter trail.
- Stop at the saddle, even if you’re going all the way.
- Pace yourself. The second half is the hard part.
- Watch the weather. Don’t hike the exposed ridge during thunderstorms.
- Stay on the trail. Don’t cut switchbacks. It causes erosion.
- Pack it out. Leave no trash behind, including toilet paper.
