Often refers to multi-day hiking trips through rural, often rugged territory. It can be as athletic and adventurous as participants decide. Many people who are trekkers engage in longer trips through entire regions of the world, using trekking as a way of getting from place to place.  It is different from other sorts of travel, tending to be less-structured, as weather conditions and topography help influence travel plans more than plane flights or hotel availability. By moving through rural areas, trekking gives travellers an up-close view of incredible scenery. Many trekkers travel through isolated areas, giving them an experience much different than those who travel in organized groups to more-popular destinations. It often allows them to interact with nature, doing anything from climbing a rock wall to navigating across a mountain or entire mountain range.
