With our 3yr old I visited the zoo yesterday. It was a chilly but beautiful sunny day and we explored the zoo together for 5 hours. Driving a little electric car on her own, taking the zoo train and riding a dolphin on the merry-go-round. Pancake for lunch obviously.
Biggest adventures were walking the rope bridge over the bear pit,
and following a hidden trail she discovered which led over tree stems across a pond, through a little cave and what she called the ‘jungle’, to the very back corner of the tiger enclosure (a path dimensioned more to her length than my so I had to duck most of the way). There we came upon a sleeping tiger which we watched and discussed for a long while.
