TrailAvalanche Peak Trailhead 5N2
4.5-mile out-and-back; 2,100 ft gain. Relentless climb with a true summit payoff.
South of Grant Village, near Lewis Lake
This 10.8-mile loop delivers moderate challenge with legitimate rewards: steady forest hike to the crystal-clear Lewis River Channel, where eagles and osprey hunt for trout in pristine water. You'll work 5-8 hours of solid effort outbound on forest trail, return on the Dogshead Trail. Not a stroll—not technical either—pure backcountry grit for committed hikers.
Moderate
Pristine forest hike to the Lewis River Channel where eagles and osprey actively hunt for trout in crystal-clear water
• The payoff is at the Lewis River Channel (mile 5-6)—pristine water and active eagle hunting; position yourself on the bank • Dogshead Trail return is psychologically longer than the outbound despite equal distance • Start before 6 AM to beat afternoon thunderstorms • The forest has dense sections where bears hide—be loud
Summer and Fall

Not technically hard, but 10.8 miles over 5-8 hours is real work. The forested terrain has no dramatic views to distract you—you're doing the miles on pure effort. Not a casual stroll.
Technically yes, but not recommended. This is bear country—solo hikers are higher risk. Go with at least one partner and tell someone your planned return time.
Yes: trekking poles (mandatory for stream crossings and descent), 2L water minimum, bear spray (required in Yellowstone backcountry), map, compass. Solid footwear is critical—stream crossings demand secure footing.
Yes, the loop is flexible. But understand you won't see the Lewis River Channel payoff unless you push to mile 5. Short-cuts don't exist on this route.
Yes—this is prime bear habitat. Make constant noise on forest sections. Carry bear spray and know how to use it. Moose are also present. Stay calm and back away slowly if you encounter wildlife.
The Lewis River Channel is your main water source around mile 5-6. Carry 2L minimum—you'll need to filter and refill. The return leg is drier. Early season means swift, cold water.
