Professional explorer Leo Houlding is no stranger to climbing. He’s been doing it since he was 10 years old and has made many major expeditions across the globe including to the summit of Everest, remote Arctic and Antarctic peaks, Yosemite, and jungles of South America. Posted on Ripleys.com, this past year, Leo decided to celebrate his 40th birthday by showing his two children, Jackson and Freya, and wife Jessica, what he loves most: climbing cool mountains and exploring new lands. The family spent four days together scaling the north ridge of Piz Badile, part of the picturesque Alps on the border of Switzerland and Italy.

Despite being only three and seven years old at the time, respectively, Jackson and Freya, successfully climbed this nearly 11,000-foot-tall mountain. Freya became the youngest person to climb the Piz Badile unaided, and Jackson was the youngest person to ever make it to the top!  Read more about this family that climbs together by clicking here.
