Get out and see the animals! I love to go see the animals on a sunny day; the latest zoo I have been to is Fuengirola Biopark. And it is probably the best zoo I have been to yet.
The animals are in habitats as opposed to enclosures, there is a great range of animals from tigers to frogs. If you do go you, have to go on a Lima tour, you get to go inside Madagascar Island and learn about the limas as they jump all around and over you!
The great thing about the Biopark is how close you can get to the animals; you can see the habitats from many different angles. Get up close to the meerkats and do your best to compare the market impression, see the big blue birds with afro hair and stand inches away from the big crocodile!
