Where to find public terrariums suited for photographers?

Hi all,

I have once tried photographing w/105 mm Nikkor macro and a handheld wireless flash in a public terrarium. It was placed somewhat out of the way in a rural area in Denmark and actually a bit hard to get to. It was very interesting though, but there was not time enough before closing time. And it was sheer luck that I was almost alone in the rooms that day and not together with too many other visitors, because that would have been a very cramped experience and the owners might then have asked me to stop my acitivities all together.

Do you know of some public terrariums (in particular European) well suited for photographers and with some especially interesting and accessible insects and reptiles etc. to photograph, and with the possibility of using tripod and/or flash? Or can you recommend a whole different technique?

I thank you in advance

Philip
