Here is the answer from Nepal trekking company:

Trekking is an outdoor recreational activity of hiking or walking for more than a day. It can be a short or an extended journey, and may or may not involve camping outdoors. In Nepal, trekking is the most widespread activity for tourists, obviously due to its privilege of being home to the Himalayas. There are many different ways to do a trek and the trekking culture often varies from country to country.
Trekking usually consists of a series of ascents and descents walking 5 to 7 hours (9 to 14 kms per day on average with a guide, cook and porters and on some occasions, pack animals. The objective of trekking is not just the particular destination, but the journey itself. You travel at a modest pace, observing nature, rural communities, and spectacular mountain panoramas. Trekking is the best way to experience Nepal’s beauty either on beaten trails or off the beaten path, which are known as virgin tracks. Nepal is a trekker’s paradise. The organic rhythm of foot travel is a wonderful way to explore and make meaningful contact with the country and its friendly people. A trekking route will often pass through forests of rhododendron, bamboo, oak, and hemlock, visiting one or two villages each day.
