I am sorry to say I had a terrible time at this program.
All we were allowed to do was clean the stables and 2 days out of 3 weeks I got to follow the vet around and see what he does. Any other activity I wanted to take part in some one asked me to pay extra, usually the mahouts.
I also was not very impressed with the standard of care. I appreciate they have lots of bulls and safety is their number one priority but I think there is a lot of room for improvement.
There was no support from some one like a volunteer coordinator and I will never go back to this project.
You do get plenty of free time but if that is what you want you can just do a tour of Sri Lanka and visit the sanctuary for a day.
I must add that my stay was 3.5 years a go so maybe things have improved. I hope so.
