The US National Park Service has laid out a schedule for when you will need a reservation to drive into or through Yosemite this year.

Park officials in Yosemite are warning visitors of what they say is "one of the most dangerous animals" in the park — and it's an unlikely culprit.

After months of delays and confusion, the Trump administration has finally announced that visitors will be required to have reservations to enter Yosemite National Park this summer, although on fewer days than last year.
