Trekking is about enjoying a great walking holiday. Treks can be day hikes, overnight or extended hikes. An example of a day trek is hiking during the day and returning at night to a lodge for a hot meal and a comfortable bed. Trekking can be more enjoyable when undertaken while being generally physically fit. Physical preparation for trekking includes cycling, swimming, jogging and long walks.
To ensure the safest experience possible it is generally a good idea to have some form of experience with basic survival skills, first aid, and orienteering when going for extended hikes or staying out overnight. It's also expected that backpackers leave no trace while enjoying the outdoors.
