(CNN) — President Barack Obama and his family are heading west Friday to visit two of the United States' national parks for Father's Day weekend.
With the National Park Service turning 100 in August, Obama wants to highlight the agency's preservation measures and make the case for fully funding its efforts.
"I want to make sure that the American people are able to enjoy the incredible national parks, the incredible beauty, the mountains, the oceans that have been one of the greatest gifts that we've ever received," Obama said in a June 9 Facebook video.
"And I want to make sure that the whole world is able to pass on to future generations the God-given beauty of this planet."
The U.S. Interior Department, which oversees the park service, reported Friday that national park sites and other non-park service sites under its authority hosted an estimated 443 million recreational visits last year, a 20 million-visit increase from the year before.
The visits were responsible for $45 billion in spending and supported about 396,000 jobs across the country, according to the report.
The Obamas hiked on Cadillac Mountain in Maine's Acadia National Park in July 2010.

A smaller version of Yosemite was first protected in 1864, during the height of the Civil War, and it became the nation's fifth national park in 1890. That was prior to the establishment of the National Park Service in 1916. Carlsbad Caverns in New Mexico became a national park in 1930.

When President Woodrow Wilson signed the Organic Act creating the National Park Service on August 25, 1916, there were 14 national parks, 21 monuments and two reservations. Rangers recorded 326,000 visits to those sites that year. (As of June 17, there are now 411 sites.)
Under his authority granted by the Antiquities Act of 1906, Obama has protected more than 265 million acres of public lands and waters, more than any other president, the White House said.
The Obamas visited the Grand Canyon in 2009.
