Also I have been to the Botanical garden in Zurich!! I was bore done day decided to check it out and was very impressed!! kept me amused for a few hours and would definitely return again!

have to say though my favourite thing of all time to do in Basel is still visit the zoo!! those damn Elephants have me hooked!! in summer love just going watching them take a bath (if I have time )
so funny after a while you realise it's a good idea to stand back but there will always be people right up the front who get soaked by elephant bath water mixed with pee and poop :P
hope this helps
