This aquarium is well located near the centre of Biarritz, and hosts a great selection of creatures. We spent a long visit enjoying watching lots of the animals and were impressed by the way some of them were carefully housed to accentuate the visual display. For example the jellyfish tank was lit with colours which cycled through red, blue, purple and so on which led to some great photos, and selection of silver fish had just the right while lighting to make them sparkle. The big shark tank was well set up with a variety of windows providing multiple view points and preventing a build-up of too many people in one place. The tropical fish tank was brilliant with a large variety of colourful fish which I could have sat and gazed at for a long time.
There were a couple of down sides: the touch pool didn't have much going on, food / drink provision was limited (vending machines only), and if I'm honest the seals didn't have a great deal of space in their tank. However overall this was a good collection and solid value for just over ten Euros.
