About This Route
From Trail of the Cedars boardwalk near Lake McDonald, this 5.9-mile round-trip route climbs steadily through old-growth cedars to Avalanche Lake, framed by Bearhat Mountain's waterfalls. Intermediate runners enjoy the mix of gentle grades and forested singletrack, but NPS strongly discourages running due to high bear density and steep drop-offs. The elevation gain of 730 feet challenges pacing; maintain awareness to avoid fatigue-induced errors.
Safety Considerations
Grizzlies frequent this popular trail; runners have surprised them, leading to charges. Shout 'Hey bear!' rhythmically and carry UDAP bear spray holstered for quick draw. Hypothermia looms from glacial lake swims or stream crossings; frigid waters (below 50°F) trigger cold shock. Rocky switchbacks pose fall risks; scout for loose scree. Afternoon thunderstorms are common; start early. REI experts advise synthetic layers only, no cotton. Monitor for altitude effects above 4,000 feet. Obey NPS group size rules for bear country (at least four people recommended).
Essential Gear
Hiking poles like Black Diamond for steep sections double as bear deterrents. Waterproof trail runners from Salomon Speedcross grip wet rocks. Emergency bivvy and headlamp for delays.
Emergency Tips
For lightning, descend quickly to lower elevation. Bear spray failure? Use rocks or sticks to fight. Signal rangers via whistle (three blasts); Avalanche Lake area has spotty cell service.
