I’m sure you had, as me, a very long half-term holidays if you live in London. The problem is in winter when you need a lot of indoor activities. And everything is so expensive in London. So we need cheap alternatives. I found this Museum that I didn’t even know it existed until yesterday.
Horseman Museum is in Forest Hill, London. It is free and it has really nice galleries to go with the children. You can discover animals, musical instruments, lots of ethnographic objects at the Africa Gallery and it has a little aquarium as well, but you need a ticket for that. My favourite was the Centenary Gallery.
As well, you can download a free App in the App Store and entertain the kids, looking for objects through all the galleries in this game. My 5 year-old loved that and kept him entertained for an hour!
Super recommended place to go with little ones.
