The family vacation comes a week after the oldest daughter, Malia, graduated from the private Sidwell Friends School at an outdoor ceremony that the family attended.

“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 have ever received,” Obama said in a Facebook video about the trip.

“I want to make sure that the whole world is able to pass on to future generations the God-given beauty of this planet I want to make sure that the whole world is able to pass on to future generations.”

Speaking at the park, Obama said park rangers were also experiencing the effects of climate change: meadows are drying out, bird migrations are shifting elsewhere and higher temperatures are sending some animals to higher elevations.

Since taking office in 2009, Obama said his government has protected well over 100 million hectares of public lands and water, more than any other previous US administration.

The park service was created in August 1916. Yosemite, near Fresno, California, is among the 10 most popular parks, with about 4 million people visiting annually. It is known for its waterfalls, but also boasts ancient giant sequoia trees and a vast wilderness area.

The park visits will cap a difficult week for Obama that opened with Sunday's shooting deaths of 49 party-goers at an Orlando, Florida, nightclub by a lone gunman.
