As the hours tick down toward a potential government shutdown, the National Park Service (NPS) is gearing up to clear out its staff across all national parks, but the parks will keep their gates open.
National parks across the country will remain open to visitors under a shutdown but most facilities — including bathrooms — will be shuttered, according to the Interior Department’s 2018 contingency plan.
That means visitors who planned to visit a national park over the holidays will still be able to do so but will have to go without guidance from any NPS officials.
