trail ma viac vyznamov, napr:
A trail, in the most general sense, is any linear route for travel. Even highways are sometimes called trails. However, in common usage, a trail is an unpaved, narrow pathway, usually through a wild area, for use by hikers, horseback riders, bicyclists, motorcyclists, or other sport users (Trail Riding). Many trails are off-limits to everyone other than hikers, and few trails allow motorized vehicles.
