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

This 1.2-mile lollipop loop climbs 150 feet through Douglas-fir forest to Trout Lake, a pristine alpine destination in Yellowstone's quiet northeast. Moderately easy terrain masks a steep, rooty final push that rewards fit legs with solitude and unobstructed wildlife viewing. The trail is well-worn and straightforward, but you're hiking prime bear habitat—silent hiking is suicide here. Expect 1-2 hours round trip if you move steadily and don't linger at the lake.
Moderately easy with a steep, technical final pitch
Pristine alpine lake in quiet northeast backcountry with minimal crowds and direct wildlife habitat access. Early morning and dusk offer elk and bison sightings.
• The trail is a lollipop—don't get confused on the return loop. Mark your entry point mentally or with a stone cairn. • Arrive before 7:30 AM to secure the parking pullout on summer weekends. • The lake itself is the payoff; most hikers turn around at the shore and don't linger. • Wildlife window is dawn and dusk—early start captures both. • The false summit (a rise in the middle of the climb) will tempt you to stop. Keep pushing; the real summit is 0.5 miles further. • Elk and bison inhabit this area; give them 25 yards minimum. Watch for calves in June-July—mothers are aggressive.
Mid-May through September for reliable Northeast Entrance Road access and stable weather
Suitable for families with kids ages 8+, comfortable with uneven terrain and 150-foot elevation gain. Close adult supervision required due to bear country and unbarriered lake edge. Kids must follow noise protocol without exception and stay within arm's reach near wildlife.
Hikers consistently rate this as a quick, rewarding escape with genuine backcountry vibes and high wildlife encounter rates. The short distance appeals to families and solo travelers seeking solitude; the bear risk and exposed parking lot keep casual crowds light, leaving the experience raw and unfiltered.
None required. Standard Yellowstone entrance fee applies.
Not applicable. Personal vehicle or hitchhike required to reach the trailhead.
You're in prime black and grizzly bear habitat—assume bears are present. No water sources on the trail itself, forcing you to carry every drop. Steep, rooty final ascent becomes slippery when wet or icy. Small pullout parking creates bottleneck on weekends. Lake edge has no barriers—watch for falls or slips.
Rooty, steep final section with loose rock. Not wheelchair accessible. Uneven forest floor throughout.

Yes, ages 8+. The 1.2-mile distance is manageable, but kids must be comfortable walking uneven, rooty terrain. The bear risk means constant adult supervision and strict noise protocol—no exceptions. Kids can't wander. You must hike the full loop; no shortcuts.
Yes, regularly. This is prime black and grizzly bear habitat. Make continuous noise, carry bear spray, and never approach wildlife. Solo travel is possible but higher risk. If you're nervous, group up with other hikers.
Yes: bear spray, 2L+ water, sturdy boots with grip for descent, trekking poles, and a map/compass or GPS. The trail is straightforward but navigation backup matters in wildlife country. Bug spray is mandatory July-August.
The 150 feet compressed into 1.2 miles creates a short, sharp climb with a steep finish. Fit hikers breeze it. Moderate fitness: doable with breaks. Bring trekking poles for the descent—they matter.
Bone dry until the lake. Carry every drop you need plus reserves (minimum 2L, ideally 3L). You cannot rely on finding water on this trail. Filter the lake if you refill, though most hikers avoid drinking from the destination.
High likelihood of elk, bison, or mule deer, especially dawn and dusk. Bears are present but rarely confrontational if you're loud. Stay 25 yards from elk/bison, 100 yards from bears. Calves (June-July) mean aggressive mothers nearby.
Technically yes, but the Northeast Entrance Road closes seasonally. Most reliable access: mid-May through September. Winter hiking requires snowshoes and avalanche awareness on the approach road; check road closure dates before driving.
