After a week focused on the aftermath of the deadly mass shooting in Orlando, President Obama leaves Washington on Friday for a three-day family tour of New Mexico's Carlsbad Caverns and California's Yosemite national parks.

The president will be joined by first lady Michelle Obama and their daughters, Malia and Sasha, on the trip, which was scheduled before the attack that killed 49 people at a nightclub in Orlando last week.

White House officials said the first family’s vacation is aimed in part to bring attention to the 100th anniversary of the federal park system, both in terms of the conservation of natural lands and the economic effect of tourism. Federal officials said 305 million people visited national parks across the country last year, an all-time high.

The Obamas are scheduled to make their first stop at the Carlsbad Caverns in the Guadalupe Mountains on Friday afternoon, before flying to California, where they will spend two days at Yosemite. They are scheduled to return to Washington on Sunday evening.
