Bushcraft with horses?

Ok, so we all have some dream holidays and 101 places we want to see before we die etc etc Among some other things I would love to do there is this one adventure idea that keeps coming back to me...If I ever find someone crazy enough to do it with me that is!

So what is it? I would love to do a couple of weeks long survival sort of trail: think tents and bareback horses, no tv, no computers, no much civilisation... Nowhere stupidly remote but somewhere unspoilt like Wales perhaps...
