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

A 0.5-mile paved boardwalk with 11 interpretive exhibits about Yellowstone's Northern Range—a grassland ecosystem sustaining one of the world's largest and most diverse free-roaming wildlife communities. This is an easy, accessible walk suitable for most ages and abilities, though the boardwalk surface is somewhat uneven with gaps up to 0.5 inches. The critical challenge is wildlife safety: bears and wolves require 100-yard distance, bison and elk need 25 yards—violate these rules and you've created a dangerous situation.
Very easy; accessible for most ages and abilities.
Explore Yellowstone's Northern Range, where one of the largest and most diverse free-roaming wildlife communities roams: bison, elk, bears, wolves, and more. Interpretive exhibits explain the ecological forces shaping this grassland ecosystem.
• Arrive between 6-8am for best wildlife activity and manageable crowds. • Bring binoculars; distance rules prevent close-up viewing but you can see animals from afar. • Take time with the tactile exhibits; they provide excellent sensory engagement. • Audio descriptions add significant context; allow extra time if using them. • Combine with nearby Mammoth Hot Springs and historic Fort Yellowstone attractions on the same visit.
