English or western, I think that the change in scenery and activity is the most valuable factor. I tend to work on many arena lessons on the trail as well (steadiness of gate, head set, and overall riding manners).
Additional lessons are learned too, as said above - getting used to new surroundings.
Trail riding is just a different learning experience than arena riding, but in my opinion just as valuable if you take it seriously.
