Be alert, especially this time of year around Mammoth Hot Springs. Elk calves may be hidden close to buildings, under or next to vehicles, and around blind corners. You must remain at least 25 yards from all wildlife. If an elk charges, retreat!
Certain trails, backcountry campsites, and fishing areas in the western part of the park near Biscuit Basin are closed until further notice to allow for an investigation following a bear-caused human injury.
Expect a single lane of traffic with up to 15-minute delays, 24 hours a day, seven days a week, from April 1 through late October 2026. Oversized/overweight vehicles (8'6"+ wide, 75'+ long, 80,000 lbs+ gross vehicle weight) will not be able to cross the bridge during this time.
Although an entrance pass is required to enter Yellowstone National Park, vehicle reservations are not needed. You are encouraged to purchase an entrance pass before arriving, but you may also purchase passes at any entrance station upon arrival.
