A trail is symbolic of being on some sort of a journey. Since a trail is usually related to something that is found in a more natural setting, the journey that is being expressed in this dream is more closely related to something personal about your nature—an inner journey as opposed to your public life.
The quality of the trail and the things that happen while you are on this trail will give you more insight into what this dream means.
[1]If you dreamed of walking on a trail, you can achieve your goal(s) if you persevere.
To dream of losing or wandering off a trail is a warning against wasting your time in meaningless activities and/or relationships.
