Trekking is an activity in which people take multi-day hiking trips through
rural, often rugged territory. 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 also can be incorporated with other outdoor sports, such as rock climbing
or backpacking. This activity is different from other types of travel for several
reasons. As travelers move on foot through often-rural areas, trekking gives them
an up-close view of the scenery. Many trekkers travel through isolated areas and
get a travel experience that is much different from that of people who travel in
organized groups to popular destinations. This often allows trekkers to interact
with nature while doing things such as climbing a rock wall or navigating through
a mountain range.Treks also have been organized in other less-visited areas on almost
every continent.
