Hi, I am moving to the Middle East and we are going to be building a house there. We have enough room for a horse barn but the arena is only 10.5m by 11m. Is that too small for a horse arena? We will only be riding the horses and we will not be giving lessons or jumping are anything like that. We will often take them outside and ride them in a big open are like the desert (since our land isn't that far away). Thank you in advance for answering. And by the way, I am getting Arabians since that is all that is available in the area I'm going to be living in.
