The Bioparc describes itself as a "zoo immersion" environment, where the barriers are hidden and the animals live in natural habitats so you can get closer to them and feel more involved.
We were definitely impressed. There is a great range of African animals in different habitats- Madagascar, Equatorial Africa and the Savannah. My photos don't do the place justice.
We enjoyed it so much (and are pretty sure that we'll be going a good few more times when we have visitors over) that we're almost certainly going to get annual passes. At just €50 each they are great value for money. I could sit and watch the giraffes roaming around for hours, and I almost certainly will do that.
The Bioparc is definitely worth a visit if you find yourself in Valencia. Children would absolutely love it as well. The only downside is that you aren't allowed to take your own food in and the prices were high (as they always are) for very small portions. That aside, it's a very enjoyable way to spend a day and I'm sure you'll see me mention it on here again!
