Hiking is for me walking on routes designed for hikers. Trekking is, for me, walking non-designed routes, like we do, me and my wife. We walk along beaches by the side of the ocean, woodland paths or just finding our ways, on country roads... and so on. But also on designed routes. Mostly about 25 kilometres (15 miles) a day for one week. There is always 100s of photos from each year trekking adventure and my wife make a photobook from our photos. That is a nice thing! So that we in the winter, when the storm is howling from northwest and the rain is hitting the windows hard, we can sit there by the fire and remember the summer vacation we were on foot. I like that!
