Yellowstone National Park is opening select roads to automobiles tomorrow, April 15. The Park’s spokeswoman Amy Bartlett explains exactly what roads are now open.

“We actually open up roads in a staggered opening to allow time for the plow crews to get rid of the snow,” said Bartlett. “Folks can get from Mammoth and West Yellowstone to both the Grand Canyon of the Yellowstone by way of north, as well as Old Faithful by way of Madison. Beyond Canyon down through Lake and Grant, and the south entrance, remains closed at this time.”

According to Bartlett, spring time is one of the best times to visit Yellowstone.

“You’re going to avoid a lot of the crowds you might encounter in summer time,” Bartlett said. “We actually had our first bison calf spotted a few days ago. The bison are starting to calf so you might be lucky enough to see one of those little red dogs running around. It is just a great time. Starting Saturday April 16 through April 24, it is actually National Park Week, so the fees into the park will be waved.”

It may be sunny in Missoula, but Bartlett says snow is still on the ground at the park. Visitors can check the road report section on the parks website to make sure driving conditions are safe.
