Mandy Moore: actress, musician, and now, accomplished mountain climber.

The This Is Us star took to Instagram over the weekend to detail her ascent up Mount Kilimanjaro, saying it had been a dream of hers to climb the 19,341-foot peak—the highest in Africa—since she was 18.

"Oddly, I’ve never felt more determined to tackle such a physical challenge before and yet the combined elements of exhaustion and extremely cold weather made it much trickier than any of us were prepared for," she wrote of the nearly eight-hour trek. "All of that aside, ultimately reaching the threshold of the true summit was more emotional and overwhelming than I had thought possible."

Moore's fiancée, Dawes frontman Taylor Goldsmith, was also along for the trip, as were a few of Moore's "best friends."

"Kilimanjaro demands a lot from those who traverse her trails. You have no choice but to show up. And we did," she concluded. "There’s nothing more empowering than realizing that we are all capable of so much more than we give ourselves credit for."
