Autorentext
Tom Martens grew up in Belgium and first visited the Pyrenees in 2008 with a friend who had made him enthusiastic about the mountain chain. This first exploration was so enchanting that he has been back every year since. He has hiked extensively in the national parks and traversed the whole length of the Pyrenees several times. He has guided groups of youngsters on long, intensive hikes and climbed many of the high peaks. So far, he has spent 500 nights in the Pyrenees, mostly bivouacking. He has a special interest in mountain wildlife. Other regions where you can often find him hiking include Scotland and Estonia, where he currently lives.
