- World Championship Hill Climb
The Legacy
A Tradition Born in the Tetons
What began as a friendly contest between local riders in 1975 has grown into one of the most iconic snowmobile competitions in the world.
Each March, the Jackson Hole Snow Devils transform Snow King Mountain into an arena of speed, grit, and community spirit. Over 300 racers from across the U.S. and Canada test their skill against a mountain that refuses to yield — cheered on by more than 10,000 spectators who fill the slopes and streets of Jackson Hole.
Unlike corporate-run races, the Hill Climb is powered by volunteers. For nearly fifty years, proceeds have funded scholarships, avalanche training, and local nonprofits — proof that horsepower and heart can go hand in hand.
Racers
Every spring, more than three hundred competitors arrive from across North America—RMSHA pros, semi-pros, and fearless first-timers—all chasing a summit only few will reach.
Spectators Annually
Jackson Hole comes alive with fans lining the mountain and cheering from every ridge. For four days, the valley turns into the loudest, most passionate crowd in winter motorsports.
of Competition
From Thursday qualifiers to Sunday’s King of Kings Finals, the event unfolds in nonstop waves of adrenaline, camaraderie, and celebration of pure mountain horsepower.
Donated Since 1975
As a nonprofit, the Snow Devils turn every throttle pull into impact—funding scholarships, avalanche safety, and local charities that strengthen Jackson Hole year after year.

There’s nothing else like it. A mountain transformed into a motorsports coliseum. Racers claw for traction up 1,574 feet of vertical terrain — an ascent so steep it’s earned global respect and local legend status.

Where Legends Are Made
Snow King Mountain
A Proud Partner of the World Championship Snowmobile Hillclimb
The Hill Climb takes place on the Exhibition Run — a slope so steep it’s visible from nearly every corner of town. Racers blast off from the base, rocketing toward the summit as engines scream and snow dust hangs in the air.
The climb is a staggering 1,574 vertical feet with a 45-degree incline through the notorious Rock Garden, a section where gravity wins more often than the riders do. Only about 60% of competitors reach the top — and those who do earn instant legend status.
