Mia and Leo's first overnight tramp is a great success, despite Mia's misgivings that younger brother Leo will be too slow. On the way to Whiowhio Hut, however, they meet other trampers, all of who have a problem with either their preparation or gear. As Mia and Leo's family are well prepared they are able to help the other trampers. Award-winning author of nature books for children, Gillian Candler, teams up with illustrator Gavin Mouldey and the New Zealand Mountain Safety Council to create this entertaining and informative story for 5-10 year old.
