TrailAvalanche Peak Trailhead 5N2
4.5-mile out-and-back; 2,100 ft gain. Relentless climb with a true summit payoff.

An 8-mile meadow loop around Garnet Hill following an old stagecoach route. Moderate terrain with river views and prolific wildlife—bears, bison, elk, wolves, and badgers frequent this area. The full loop is currently affected by a washout; check Backcountry Conditions before heading out. Expect 4-5 hours of hiking with constant wildlife awareness required.
Moderate
Scenic Yellowstone River views, abundant wildlife encounters (bears, bison, elk, wolves, badgers, mule deer), historic stagecoach road section, varied terrain from open meadows to forested passages. The eastern loop around Garnet Hill offers the best river exposure.
• The washout prevents completion of the full loop—most hikers do the eastern Garnet Hill section only, which is the scenic payoff anyway. • The stagecoach road section (first 1.5 miles) is deceptively easy; difficulty increases sharply after the shelter. • Elk Creek section north of the shelter is quieter than the Garnet Hill loop and offers solitude. • Early morning (before 8 a.m.) yields the best wildlife viewing and reduces encounter risk due to lower hiker volume. • The false summit at Mile 5 will deceive you—the actual loop rejoins at Mile 6+. Keep pushing.
Mid-April through early November when most park roads are open. Summer (June–September) offers the most stable weather and longest daylight.
Suitable for families with hiking experience and older children (10+). Constant wildlife supervision is mandatory—never let kids wander. The 4–5 hour duration demands good fitness and endurance. Teach kids how to respond if horses approach (move to downhill side, stand still). This is not a leisurely family stroll.
Hikers praise river views and wildlife encounters but report the trail washout limits full-loop completion. Fitness and wildlife awareness are non-negotiable; this is a moderate tactical challenge due to bears and bison, not terrain difficulty.
Day-use hiking requires no permit. Check the NPS Backcountry Conditions report for current trail status before departing.
Not applicable—single trailhead, no shuttle service
This area is home to many bears and bison; constant caution is non-negotiable. Trail is frequently used by horseback riders—move to the downhill side if horses approach and remain still until they pass. The full loop is currently affected by a trail washout; refer to the NPS Backcountry Conditions report for current status. River sections have exposure and loose footing; stay alert near drop-offs and variable terrain.
Not wheelchair accessible. The 8-mile loop has topographic features and trail conditions unsuitable for mobility devices.

Tower Junction has a service station. Roosevelt Old West Dinner Cookout is located at a shelter 1.5 miles into the hike (seasonal operations). No other services within the first 1.5 miles.

Yes—many. This is prime bear country. Carry bear spray, make noise constantly, and know how to use your spray. This is non-negotiable. If you're not comfortable with bears, skip this trail.
Moderate means 4–5 hours of consistent walking on mixed terrain. The first 1.5 miles are easy; after the shelter it gets harder. If you can hike 5 miles with moderate elevation elsewhere, you can do this section. Fitness is mandatory.
Yes, but they need hiking experience and you need constant wildlife supervision. The 4–5 hour duration suits older kids (10+). Teach them about horses on the trail and how to react if wildlife appears. Never let them wander.
No day-use permits are required for this trail. Just check Backcountry Conditions before you go—the washout status and trail access may affect your route plan.
The washout prevents the full loop, but most hikers do the eastern section (Garnet Hill loop) only, which is the scenic part anyway. Check the NPS Backcountry Conditions report for current details before leaving.
2–3 liters minimum. Elk Creek and Yellowstone River are nearby but require filtering. Better to carry enough than depend on unreliable sources in this remote area.
Move to the downhill side of the trail, stay still, and let them pass. Don't make sudden movements or shout. Trails here are multi-use and horses have the right-of-way.
