President Obama trekked the Alaskan wilderness on "Running Wild With Bear Grylls," which aired on NBC Thursday night.
The episode, which was filmed in September, is part of Obama's ongoing push to highlight the effects of climate change — while showing the more adventurous side of the president.
Obama and Grylls ate wild salmon that was picked at by a bear, shared tea made out of catkins and discussed fatherhood, fears and Gryll's habit of drinking urine.
"He said it was one of the best days of his presidency," Grylls told reporters on Monday, according to Reuters. "There were times along the route I had to pinch myself and think, actually, this is the president of America'."
