Jacquetta Megarry climbed Kili four times between 1999 and 2008, by Marangu, Machame, Rongai and Lemosho routes. She has trekked at altitude also in Nepal, Peru and Morocco, and has taken part in medical research on how altitude affects climbers. She devised the Rucksack Reader format to suit the needs of long-distance walkers, and has also published a series of Rucksack Pocket Summits for those who wish to climb the Seven Summits.
"Colourful, concise and comprehensive: this is the guidebook that I took up Kili with me." Sir Chris Bonington
