Travelers and residents of Wyoming, Montana, Idaho and surrounding states should start preparing now for the seasonal shutdown of Yellowstone National Park’s road network. Beginning in mid‑October, the majority of park roads will close for the winter and remain shut until the spring melt, leaving only the north‑entrance corridor open year‑round.

Roads Open Through Mid‑October

For the 2026 season, the following routes stay open from April 17 through October 31:

• West Entrance to Madison
• Madison to Old Faithful
• Madison to Norris
• Mammoth Hot Springs to Norris
• Norris to Canyon Village

These primary arteries give visitors access to the park’s most‑visited geyser basins and historic sites.

Later‑Closing Roads

Additional roads remain open a bit longer, but will still close before winter fully sets in:

• East Entrance to Fishing Bridge (Sylvan Pass) – open May 1 to October 31
• Canyon Village to Bridge Bay – open May 1 to October 31
• South Entrance to West Thumb – open May 8 to October 31
• West Thumb to Old Faithful (Craig Pass) – open May 8 to October 31
• West Thumb to Lake Village – open May 8 to October 31
• Tower‑Roosevelt to Tower Fall – open May 8 to October 31

These routes serve the park’s southern and eastern sectors, including the scenic West Thumb area and the Tower‑Fall region.

High‑Elevation Passes Close Early

Two high‑elevation corridors close on October 12, reflecting their greater exposure to early snow and severe weather:

• Canyon Village to Tower Fall (Dunraven Pass)
• Beartooth Highway (US‑212) and Chief Joseph Scenic Byway (WY‑296)

Both passes are subject to change if weather conditions deteriorate faster than expected.

How to Stay Informed

Drivers approaching the park should monitor conditions closely. State transportation departments provide real‑time maps and mobile apps:

• Wyoming – WYDOT 511 map or app
• Montana – 511MT map or app
• Idaho – 511.Idaho map or app
• Grand Teton corridor – WYDOT 511, the 511 app, or the GRTE roads map

For the most current road status, consult the live road‑status map on the park’s website, call the park information line at (307) 344‑2117, or sign up for text alerts by sending “82190” to 888‑777.

Safety Tips from the National Weather Service

The National Weather Service reminds travelers that winter weather can arrive quickly in the mountains. Carry chains, keep fuel tanks topped off, and dress in layers. If conditions become hazardous, turn back early and seek shelter.

Why These Closures Matter

Seasonal road closures protect both visitors and park resources. By limiting vehicle traffic during the snow season, the park reduces road wear, minimizes wildlife disturbances and helps maintain the pristine winter landscape that draws photographers and outdoor enthusiasts from across the country.

Plan ahead, check the latest updates, and enjoy Yellowstone’s spring thaw when the roads reopen.
