Hi
Just wanted to recommend Go Ape to everyone. I don't know if it has been mentioned before, but my 2 dds absolutely loved it. We did the one at Buxton in Derbyshire, and apart from me being absolutely petrified, the kids thought it was the best thing ever. It is so refreshing to find an activity that is really challenging for older kids. Although I think it is most challenging for adults - the kids seemed happy to run round it and particularly enjoyed the "extreme" activities.
The zip wires were the longest I have ever seen.
Go, but don't go if you are frightened of heights.
