(CNN) - Nearly 331 million people visited the National Park Service's 417 sites around the United States in 2017, a slight dip from the 331 million record-breaking visits during its centennial anniversary year in 2016.

Park service officials expected the slight decline after the centennial celebrations during the previous year. In 2016, the park service recorded its third consecutive all-time attendance record, and 77 national park sites set new records for annual recreation visits. (Of the 417 sites in the National Park Service, 385 count visits.)

While attendance numbers remained relatively stable, people actually spent more time in the parks in 2017 -- more than 1.4 billion hours last year, an increase of 19 million hours over 2016.

"Our National Parks are being loved to death," said US Interior Secretary Ryan Zinke in a statement, whose agency oversees the National Park Service.

"As visitor rates continue at a high level, we must prioritize much-needed deferred maintenance including aging facilities, roads and other critical infrastructure. President Trump's proposal to establish a Public Lands Infrastructure Fund is a step in the right direction. This is not a Republican or Democrat issue, this is an American issue, and the President and I remain ready to work with anyone in Congress who is willing to get the job done."

Zinke was referring to the $11.6 billion in deferred maintenance at the nation's 417 National Park Service sites, which include the 59 headliner National Parks as well as national recreation areas, seashores, parkways, memorials, battlefields and more. Increased attendance at the destinations, only 118 of which charge admission, means that many locations can't keep up with repairs.

To make the point, the National Park Service released cost estimates for deferred maintenance at each of the top 10 most popular park sites and national parks.

Top three parks attract more than 40 million visits

The Blue Ridge Parkway (16 million visitors) took back the number one slot from 2016 winner Golden Gate National Recreation Area, which came in second place with nearly 15 million visitors last year.

Great Smoky Mountains National Park (11.4 million) came in third place, followed by Gateway National Recreation Area (9.2 million) and the Lincoln Memorial (nearly 8 million).

The top 10 park sites attracted more than 5 million recreation visits each, including Lake Mead National Recreation Area, George Washington Memorial Parkway, Natchez Trace Parkway, Grand Canyon National Park and the Vietnam Veterans Memorial.

Trump's first year in office

President Barack Obama created more than a dozen National Park Service monuments during his eight years in office, including four in his final days. Some of those sites honored the country's civil rights struggle, African-American history, Japanese-American history and the fight for women's rights.

While President Donald Trump hasn't created any new NPS monuments during his first year in office, he did sign legislation to expand park service sites. Among his actions: He signed congressional legislation creating a new national historic park for Martin Luther King Jr., expanding what was a national historic site. He also signed legislation to create an African American Civil Rights Network within the National Park Service.

What's attracted a lot of attention doesn't involve the National Park Service at all. Trump signed two presidential proclamations on December 4 after declaring that he would reduce the size of two Bureau of Land Management monuments in Utah. (Like the National Park Service, the Bureau of Land Management is within the Department of the Interior.)

The two presidential proclamations split Bears Ears into two national monuments and Grand Staircase-Escalante into three separate monuments.

In response, a group of Native American tribes filed a lawsuit against Trump and several administration officials claiming that his decision to shrink the Bears Ears National Monument significantly is "in violation of the United States Constitution and the Antiquities Act of 1906."

Separately, US conservation organizations sued Trump and Zinke for actions regarding the Grand Staircase-Escalante National Monument. (Obama created Bears Ears, and President Bill Clinton created Grand Staircase-Escalante.)

Free for fourth-graders

Every fourth-grader around the country can still get a free one-year national parks pass for the student and his or her family under the "Every Kid in a Park" program, which has attracted more than 350,000 fourth-graders in its first two years of operation.

Correction: A previous version of this story incorrectly referred to Bears Ears National Monument and Grand Staircase-Escalante National Monument as part of the National Park Service, which is part of the Department of the Interior. They are part of the Bureau of Land Management, which is also within the Department of the Interior. This story also has been updated to clarify and add context about President Donald Trump's actions regarding National Park Service and Bureau of Land Management sites.
