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

An easy 5.8-mile round-trip day hike to Shoshone Lake, Yellowstone's largest backcountry lake. The trail alternates between shaded forest and full-sun meadows, rewarding hikers with consistent moose, sandhill crane, and water bird sightings. Suitable for most fitness levels, but the distance and sun exposure require genuine hydration discipline.
Easy
Shoshone Lake is Yellowstone's largest backcountry lake, and this trail delivers reliable wildlife encounters—sandhill cranes, moose, and water birds are common. The meadow sections provide rare open views and flat terrain, making it accessible for most hikers while still feeling remote.
• Early morning (6–9 AM) offers maximum moose and crane activity. Afternoon visits are dusty and hot. • Binoculars are essential; crane identification and moose spotting reward close attention. • The lake comes into view around mile 4.5—this is the payoff. Rest here, hydrate aggressively, and turn back. Do not enter the backcountry. • Carry a water filter or bladder; the trail itself offers no reliable water mid-route. • Backcountry Situation Report (NPS) is updated daily; check it the morning of your hike for wildlife density and warnings.
Summer and fall; road access typically mid-May to early November (weather-dependent)
Suitable for older children (10+) with prior hiking experience. Moose and bear encounters are possible—brief children on wildlife safety and maintain close supervision. Teach them to make noise on the trail. Lake shore is gentle; no steep drop-offs. The flat terrain is kid-friendly; the sun exposure and 5.8-mile distance are the real challenges.
Hikers rate this as an achievable day hike with consistent scenic rewards and excellent wildlife viewing. The flat terrain makes it accessible for most fitness levels, though the 5.8-mile round trip requires stamina and water discipline. Reviewers consistently praise the moose encounters and pristine lake setting, but note that sun exposure and mosquitoes (summer) are the real obstacles.

Yes. No scrambling, no exposure cliffs, no steep climbs. The challenge is the 5.8-mile distance and full-sun meadow sections: if you can walk 6 miles steadily, you can do this.
Yes. Black and grizzly bears are present. Make noise constantly. Carry bear spray if comfortable. Stay alert; this is their home, and you're a visitor.
Yes, but file a hiking plan with a ranger. Start early (6 AM), finish before dusk, and carry a whistle or satellite communicator. Buddy up if anxious about wildlife.
Stop. Keep 25+ yards back. Never approach. Back away slowly if it approaches you. Moose kill people—respect the distance.
Not required, but recommended. Boggy meadow sections and the return descent benefit from pole support; poles reduce knee strain on the full distance.
Carry 2L+ water, a hat, sunscreen, insect repellent (June–August is brutal), and a basic first aid kit. Waterproof boots help on marshy sections and boggy areas.
Fit hikers: 3 hours. Moderate pace: 4 hours. With photo stops and wildlife gawking: 5–6 hours. Plan for the full window; don't rush the return in darkness.
