Jeffry Oonk

A passionate outdoorsman, Jef works as a trekking, trail running, nature, and dog sledding guide across some of the world’s most remote landscapes. He holds a Master’s degree in biology and spent a decade as a wildlife photographer, tracking great apes before transitioning to guiding safaris in East Africa. With years of experience and a deep connection to the natural world, Jef is committed to helping others explore and appreciate diverse environments—from Arctic tundra to desert, from Scandinavia to Antarctica, and from the Himalayas to his native Netherlands.
