'Go Ape' at Bristol Zoo

Currumbin Sanctuary in Australia has one that opened late last year. They didn't need to put in poles - they built platforms up in the trees. It has increased visitation (and revenue) significantly and I was told that during school holidays they can have as many as 300 on the course at the same time. I tried it out and found it to be a lot of fun, although some muscles were aching a few days later.
