Most of you seem to think the same way I do. When I say trail rides are "fun" as opposed to "work," I just mean we don't really do anything we would typically do in the arena out on the trails. A horse needs to be stimulated mentally, and if you go in the arena 5 days a week and do the same thing over and over, it becomes "work" and eventually, the horse will resent it. It needs to be mixed up. The trail ride is a reward, my horse doesn't have to carry herself like we're in a dressage test, she just gets to walk. Or trot, or canter, or jump. My horse loves to be ridden. She actually gets really depressed if I go more than a few days without riding, but I make sure that I take her out whenever I have time, whether it's a long trail ride up in the hills, or just a ride behind the pastures after an arena ride.
