Avalanche closures are routine, not rare
UDOT counts 64 avalanche paths crossing SR-210, and more than half the highway sits under avalanche threat. Closures for avalanche control, sometimes with little notice, are a normal part of a canyon winter, not an emergency exception.
Snow tires or chains are the law, November 1 to May 1
Utah requires snow tires or chains in the canyon for that entire window, and UDOT can restrict travel further to snow tires, chains, or 4-wheel drive only when conditions call for it. Follow UDOT Cottonwoods and the signs at the canyon mouth. Restrictions can change within the hour.
A toll and more buses are coming
UDOT's Little Cottonwood Canyon plan adds a peak-period toll (proposed around $25 to $30 on busy ski days, not year-round) and more frequent buses, every 10 to 20 minutes instead of every 30, as part of a longer-term plan that also includes a proposed 8-mile gondola. Phase 1 details were still being finalized as of spring 2026. Check UDOT's own Cottonwood Canyons page for what's actually in effect this season.
Are chains or snow tires required in Little Cottonwood Canyon?
Yes, by state law, from November 1 to May 1 every year. UDOT can tighten that to chains or 4-wheel drive only when conditions require it.
How high are Snowbird and Alta?
Snowbird's base is 7,760 feet, Alta's is 8,530 feet. Both are up SR-210, 13.6 miles from the canyon mouth in the Salt Lake Valley.
Is there a toll for Little Cottonwood Canyon?
Not yet as a fixed daily charge, but UDOT's approved plan adds a peak-period toll on busy ski days as part of a phased rollout, alongside more frequent bus service. Check UDOT's Cottonwood Canyons page for what's actually running this season.
