When President Obama left the bubble of the White House to “run wild” in Alaska with adventurer and wilderness expert Bear Grylls, things got, well, a little wild.

The full episode of the Commander-in-Chief’s “Running Wild with Bear Grylls” appearance does not air until Dec. 17, but the host offered a taste of what the two got into during their Alaskan trek—including eating a piece of salmon that a bear had nibbled before they got to it.

“I found an old fish that a bear had munched on beforehand and cooked it up for him,”Grylls wrote for the Sunday Times Magazine. “We shared water bottles, food…everything.”

According to Reuters, Grylls told reporters Monday he and the President were accompanied by about 50 Secret Service agents, a food taster, snipers and a helicopter during the day-long adventure designed to give the President a close look at the natural environment and the impacts of climate change.

Grylls said the President was “up for anything” during the trek.

“He said it was one of the best days of his presidency,” Grylls said. “There were times along the route I had to pinch myself and think, actually, this is the President of America’.”

Obama’s episode airs Dec. 17 at 10 p.m.
