My horses go to trail rides, the mountains, compeditive trail competitions, etc with no problems, but it takes a while for a new horse to get used to completely new everything when they first come.
If I get a new horse I put them in with my other horses the first day and am riding them that day and every day after. They have to get use to stuff and get in the swing of things right away.
