Yellowstone opens April 17

Yellowstone is reopening in pieces, not all at once, and the first cars get in at 8 a.m. on Friday, April 17, 2026, if weather holds. The two gateways opening that morning are the North Entrance at Gardiner, Montana, and the West Entrance at West Yellowstone, Montana. (nps.gov) That sounds bigger than it is. Most park roads are still closed in early spring, and the National Park Service says additional roads will open through May, with dates still tied to snow and plowing. (nps.gov) From those two openings, visitors can reach Mammoth Hot Springs, Lamar Valley, Norris Geyser Basin, Grand Canyon of the Yellowstone, Old Faithful, and the Northeast Entrance toward Silver Gate and Cooke City, Montana. That means a traveler coming in from Gardiner or West Yellowstone can cross a large north-and-west slice of the park, but not the whole loop. (nps.gov) Yellowstone works like a mountain road system with one giant ring and several spokes, so one closed segment can block an entire route. In mid-April, the road between the North and Northeast entrances is already open year-round, while the West Entrance roads are the big seasonal change arriving on April 17. (nps.gov; nps.gov) The reason for the staggered opening is simple: Yellowstone sits high, storms can still hit in April, and road crews are clearing snow from mountain passes before regular traffic is allowed back in. The park’s current alert says most roads were still closed to all vehicles as of March 16 while spring plowing was underway. (nps.gov) The park is also warning people not to plan this like a July trip. Many trails and boardwalks are still snow covered in April, services are limited from early November through late April, and temporary road closures can happen without notice if conditions turn bad. (nps.gov; nps.gov) Even when the road is open, the drive may not be quick. Yellowstone says visitors should expect delays of up to 30 minutes from road improvement projects, on top of the usual spring slowdowns from ice, gravel, and animals using the pavement as a travel corridor. (nps.gov) That last part is not a metaphor. The park says bison, elk, bears, and other wildlife often walk directly on the roads in spring because roadside snowbanks make it harder for them to move off the pavement. (nps.gov) The safety rules are strict because Yellowstone is one of the few places where a traffic jam and a bear sighting can be the same event. The National Park Service says stay at least 100 yards from bears, wolves, and cougars, and 25 yards from all other wildlife. (nps.gov) If you are trying to visit in the second half of April, the practical move is to pick one entrance and build the day around the roads that are actually open from that gate. Yellowstone is open 24 hours a day all year, but the park says road status can change quickly, so the real trip plan starts with the current conditions page, not the map in your head.
