She received the help of a guide and her brother to place water caches along parts of her route. In 2006, she followed part of the Andes from Chile to Machu Picchu 7000 km for eight months. She hiked through the Andes of South America for eight months in 2006. In 2000, she walked border-to-border across the United States in four months, and she spent seventeen months of 2002–03 walking across Australia, covering a total distance of 8,700 miles (14,000 km). Her subsequent travels included canoeing through Algonquin Provincial Park in Canada, camping in Patagonia, and hiking the United States' Pacific Crest Trail. Marquis cites a trip she took to New Zealand in her twenties as the first time she "actually got in touch with the wild": she spent a month in Kahurangi National Park without bringing any food. At age seventeen she traveled to Turkey, where she rode a horse across the Central Anatolia Region. She began exploring at a young age, and at sixteen years old she took up a job with a European train company so that she would be able to travel for free. Her father worked as a watchmaker for Swatch and her mother was a housewife, and she had two brothers. Marquis was raised in Montsevelier, a village in the Canton of Jura in northern Switzerland. In 2011, she gave a TED talk and in 2014 she was named one of National Geographic's Adventurers of the Year. From 2010 to 2013, she walked 20,000 kilometres (12,000 mi) alone from Siberia to the Gobi Desert, into China, Laos, Thailand, and then across Australia.
