“The tickets are selling out very quickly,” said Gina Kerzman, a spokesperson for Glacier National Park. Tickets for June have already been snatched up, but more may become available. Other national parks from Zion to Rocky Mountain are implementing a similar system. Phil Francis is the chairman for the nonprofit Coalition to Protect America’s National Parks. He said it’s a good thing to manage visitation for parks across the Mountain West, especially during the pandemic. “It's a better chance that people can maintain their social distance following the CDC guidelines. It provides for [a] better visitor experience," Francis said.
