Let me just say that each case is different but I am an insurance agent and I have done several boading facility. The insurance for boading and liability insurance really isn't too bad, however pony rides are ridden as a supplement to the policy. I have yet to have a facility decide to do the pony rides after seeing the requirements and the cost of the insurance. Pony rides have a much greater risk of injury and the a high risk of "pain and suffering". A general quote is very difficult to say because of so many variable ie, where do the rides take place, helmets required, number of ponies, handle experiment.
