I think it is important to make sure that your horse is well-adjusted. The first time I moved my horse, I was riding right away. The second time I switched her, it took me several weeks to be able to move into my regular training routine again. The stable setup is a lot different for her now than it used to be and the adjustment took a little longer. I think you'll have to see how comfortable your horse is. Just be cautious as he is in a new situation. Good luck!
When I moved my horse into my last boarding-barn situation, I took him out the same day and went on a group trail ride. It wasn't really planned - I just went to check on him and was invited to join a group that was going out for a short evening ride.
Unless it involves a long haul to get to our destination, there's no reason why I wouldn't take my horse out the day of arrival for just a bit of exercise. When we haul 6+ hours for a camping trip, though, we usually give them the rest of the day to just "chill" and start riding the following day.
It also helps to know your horse, and how it responds to the change.
Ride right away. If you're going to a show, you won't let your horse adjust for days or weeks, why should a new barn be any different? Even just a light hack to get the hotse's attention on you right away would be good.
When I got Ronan delivered to me, I rode within an hour of signing the sales papers.. When he got moved to the new facility I tacked up right away and went for a ride. Posted via Mobile Device
My trail horse I'll give him the day and night to settle in then a few days later I'll walk the main trail with him so there aren't any real surprises then we'll go for a ride. After we've got the main trail down we'll start exploring other places. My show horse will just get some ring work done when we first get there to get used to the new horses in the ring and then ridden once he's relaxed and stretched out.
