When i first started opening my garden for customers and locals, I used to put signs up everywhere, warning of problem areas, and also to say that no liabilty could be offered by me, so that visitors walked round at their own risk. eg, crossing a small bridge over a stream. Although we had covered the boards walked upon with chicken wire, I stressed on a sign, it could be slippery and that there were other routes if preffered etc....

I have a horrible feeling that putting up At your Own Risk notices does not absolve you from liability. (I have been told that if a child drowns in your garden pond even though you have a locked gate and Keep Out notices you are still liable) It is an unfair world. I think you would be well advised to ask a couple of insurance companies for advice, or at least ask at your citizens advice bureau. Alternatively, you might ask the organisers of your local Open Gardens scheme as this is a problem common to all who open their gardens. www.ngs.org.uk
