Trekking is journeying on foot, horse or pedal cycle or skiing over terrain which is moorland or more than 600 metres above sea level; and from which it would take more than 30 minutes travelling time to reach any accessible road or refuge; but it does not include skiing on a prepared and marked-out ski-run.
The most familiar trekking activities include hill walking, mountaineering, fell running, orienteering, pony trekking, off-road cycling and off-piste skiing.
