A great place often used by my brother Chris, who has autism and complex needs. 

From the farm:

Our aim: To enable disadvantaged people gain proven and measurable benefits through becoming more physically active and engaged through farm work and interaction with animals and nature. 

Where: Our 7 acre purpose built site near Heathrow Airport provides many activities in a safe non judgemental environmentActivities: Tailored to suit individual abilities and needs

Outcomes: measurable and recorded. An example is horse riding lessons where initial fear is always overcome and the benefit achieved by the rider is very clear
