Lost Adventures is a travel agency and was founded by Mikkel Legarth from Denmark, with the mission providing immersive and unforgettable wilderness experiences that connect travelers with Africa's natural beauty and diverse cultures while also supporting wildlife conservation efforts.

Mikkel's commitment to wildlife developed during a 9-month placement at a wildlife volunteer project in Namibia in 2008/09, where he built a bond with a leopard called Lost. This experience led him to shift from his dream of becoming a commercial pilot to supporting the wildlife that had come to mean so much to him. The resulted in co-founding the Modisa Wildlife Project in Botswana with Valentin Gruner in 2010.

The project aimed to promote and support Botswana's wildlife while easing conflict between humans and animals through cooperation with local and foreign researchers. Modisa Wildlife Project gained international attention after a Daily Mail front-page story in 2013 featuring Sirga, a lioness and member of the Modisa family. The story went viral and ended on CNN, BBC, Børsen and RTL to name a few which led to Mikkel's TEDx Talk and the creation of the award-winning series "Saving Sirga: Journey into the Heart of a Lion" previously featured on Netflix, Animal Planet, ViaSat Nature and Amazon Prime.

In 2018, he founded Lost Adventures, named after the leopard he met in Namibia, to continue his wildlife conservation efforts and to share his love for the African continent with others.
