Trail profile

Distance Miles: 6.2
Route Type: Out-and-back
Difficulty Level: Moderately Strenuous Lung-Buster
Elevation Gain Feet: 1000
Estimated Time: 3 to 5 hours for fit hikers. Expect 4.5-5 if you're feeling the descent or stop for photos and fishing.
Trail Surface: Dirt with embedded rock; steep, rooty descent to bridge. Plateau section is packed dirt with exposed roots and scree. Loose terrain throughout.
Trail Features: Yellowstone River Suspension Bridge
Sagebrush plateau vista
Hellroaring Creek confluence
Fishing access (both river and creek)
Trail Highlights: The suspension bridge crossing is the centerpiece: psychologically intense, structurally sound, framing dramatic river gorge. Plateau crossing offers panoramic Northern Range views and solitude. Hellroaring Creek confluence provides water access and quiet spot for lunch or fishing.

Trailhead Location: 3.5 miles west of Tower Junction via short dirt road to small parking area
Parking Lot Size: Small (roughly 20-30 vehicles)
Parking Fill Time: By 9am on summer weekends; mid-morning weekdays
Shuttle Required: 0
Shuttle Details: No shuttle available. Drive own vehicle to trailhead lot. Dirt road adds 10 minutes from Tower Junction.

Permits & conditions

Permit Details: Day hiking permitted without permits or reservations. No backcountry overnight allowed—day hike only to Hellroaring Creek confluence.
Fees: $35 per vehicle (standard Yellowstone entrance fee, 7-day pass). No additional trail-specific fee.
Trail Status: Typically Open (seasonal)
Seasonal Closures: Winter closure mid-November through April due to snow and road closures.

Facilities & rules

Restrooms At Trailhead: 0
Water Sources: Hellroaring Creek at 3+ miles (turnaround point). Filter all water. Trail is dry until creek—carry minimum 2 liters.
Accessibility: Not accessible. Rooty, steep descent with uneven, rocky terrain. Requires strong leg and balance stability.

Safety & strategy

Hazards: Steep terrain and loose rock on descent
Exposed suspension bridge crossing
Dehydration risk on exposed plateau
Full-sun heat exhaustion potential
Bear habitat—active Northern Range
Creek crossings in high water
Navigation confusion at trail junctions beyond bridge
Falling rock hazard
Hazard Details: Descent to bridge is steep with loose rock—fall risk is real for inattentive hikers. Suspension bridge sways and is psychologically intense but structurally sound; crossing requires commitment. Plateau is exposed scrubland with zero shade and intense solar radiation—dehydration and heat exhaustion are primary hazards. This is active bear country; make continuous noise. Creek crossings can be challenging in high water (spring). NPS warns of confusing trail junctions beyond bridge; stay focused on Hellroaring Trail markers.
Cell Service: Unknown (likely none in this remote northern park area).
Crowd Level: Moderate. Less trafficked than major geyser basin trails; busier than Blacktail Plateau trails. Solitude increases the further you go.
Peak Crowd Times: Mid-morning (9am-1pm) on summer weekends; weekday mornings are quieter.
Best Season: Summer and early fall (June-September). Most park roads open mid-April; trail is snow-free by June. Season closes mid-November due to snow.
Best Time To Visit: Start before 7am to beat peak sun exposure on the plateau. Mid-June through September when roads are clear. Morning conditions cooler and safer for exposed terrain. Avoid afternoons July-August when heat peaks.
Tips Advice: Carry minimum 2-3 liters of water—this trail is bone-dry until Hellroaring Creek at 3+ miles.
Trekking poles essential for steep, loose-rock descent and returns.
The suspension bridge creaks and sways—normal. Keep moving confidently; don't stop on it.
Make constant noise (talk, sing, bear bells)—this is prime bear habitat.
Turn back if darkness approaches; the return climb is treacherous after sunset.
Sun protection mandatory: hat, sunglasses, high-SPF sunscreen.

More details

Park Area: Tower Junction area, northern part of park
Trail Markers: Well-marked main trail to Hellroaring Creek confluence. Junctions beyond the bridge can be confusing; NPS explicitly warns to pay attention to signage and stay on Hellroaring Trail.
Dogs Allowed: No. Pets are not permitted on this trail.
Biking Allowed: No. Foot travel only.
Shade Level: None on plateau section. Full sun exposure on sagebrush. Limited shade near river and creek bottom. Wear sun protection; this is relentless solar radiation.
Emergency Contacts: Mammoth District Ranger Station (~30 miles away). Dial 911 if in service area. Carry communication device.
Map Recommended: 1
Snow Dates: Mid-November through May (typical closure for northern Yellowstone)
Mud Season: April-May and after heavy summer rain. Trail becomes slippery when wet.
Wildflower Peak: July-August
Fall Colors Peak: Late August through September (aspen stands)
Bug Season: June-August. Mosquitoes peak mid-July. Bring bug spray and wear long sleeves.
Insider Tips: The suspension bridge creaks and sways—completely normal. Don't stop on it; step confidently and keep moving.
Water at Hellroaring Creek must be filtered before drinking; popular fishing area.
Early morning hikers often spot elk, bison, or wolves on the plateau.
The return climb is deceptively hard; many underestimate the energy needed ascending the plateau after the creek section. Backcountry trails branch off beyond Hellroaring Creek—not part of standard day hike; stay on marked trail.
The plateau section can feel psychologically taxing due to exposure and heat; have mental prep for that.
Recent Updates: No recent major closures or condition changes. NPS continues monitoring bear activity in the Northern Range.
Family Friendly Notes: Not recommended for young children. Suspension bridge crossing demands comfort with exposure; children must have strong hiking experience and steady legs. Steep sections require hand-holding. No shade or water nearby—families need discipline about hydration breaks and pacing. Older kids (12+) with hiking experience can succeed with close supervision.
Nearby Facilities: Tower Fall Campground (~5 miles away). Mammoth District Ranger Station (~30 miles). No services at trailhead itself.
Review Summary: Hikers consistently report this is a genuine lung-and-leg buster with the suspension bridge and plateau exposure testing both fitness and nerve. The solitude is a major draw—far fewer crowds than geyser trails. However, dehydration, sun exposure, and the psychological challenge of the bridge are real hazards. Those disciplined about water and fit enough for sustained elevation find it deeply rewarding.

Frequently asked questions

How hard is the suspension bridge crossing really?

It's structurally sound and safe, but psychologically intense if you're uncomfortable with heights or exposure. It sways a bit—completely normal and designed for that movement. Don't linger; step confidently and keep moving. Most hikers report it's the mental crux, not a physical hazard.

Can I do this solo?

Yes, but with respect. This is bear country—make continuous noise (talk, sing, use bear bells). Carry a communication device if possible. Tell someone your itinerary. Solo hikers report isolation kicking in mid-trail; be mentally prepared for that silence.

Will I actually see wildlife?

Highly likely. This is the Northern Range—elk, bison, wolves, and bears live here. Make noise constantly. If you encounter a bear, don't run; back away slowly and calmly. Respect distance (100+ yards from bears).

How much water do I really need?

Minimum 2 liters, ideally 3. The plateau has zero shade and intense sun. No water source until Hellroaring Creek at 3.1 miles in. Dehydration is the #1 reason hikers struggle. Bring more than you think; many underestimate this trail's water demands.

What if I get lost after the bridge?

Trail junctions beyond the bridge confuse hikers regularly. NPS warns about this explicitly. If unsure at a junction, backtrack to a marked spot. Your turnaround point is Hellroaring Creek confluence—don't push beyond it on a day hike. Carry a map.

Is this crowded compared to other Yellowstone trails?

Moderate crowds mid-day in July-August, far fewer than Old Faithful or Grand Canyon trails. Start by 7am and you'll have plateau solitude. Afternoon arrivals will see other hikers on the return.

What happens if weather turns bad mid-hike?

The plateau offers zero shelter. Descend to the river area where trees provide some cover. Afternoon thunderstorms are common in summer; if you see them forming, turn back immediately. Electrical storms are dangerous on exposed terrain.
