Early November That is what the National Park Service publishes, read October 15, 2026. The gate goes in when the snow does, so the date moves from year to year. No 2026-27 dates were posted on the source page when it was read.
Mid-May Plowing and avalanche work set the day, and the agency announces it when the road is ready.
9 miles from Cooke City to Pilot Creek closed to wheeled vehicles in winter; open year-round WY-120 to Pilot Creek Parking Lot (4 miles toward Cooke City from the WY-296/US-212 junction). The rest of US-212 is handled like any other road in Montana and Wyoming.
