I have visited a number of horse farms in the Lexington area as a result of booking tours with companies that take you to two or three horse farms. However, I have not been able to see some of the better farms that way, and that would include ones like Lane's End, Three Chimneys, Gainesway, etc. I am not sure if you can even book private tours of any of those. Is there some easy reference available that shows which horse farms offer private tours, and any limitations on those tours (days of week, timing of tours, etc.)?
