Don't be daunted by how far out of Central London this park is - it's totally worth the trip! Richmond is a really lovely area full of greenery and picturesque streets, and this has to be my favourite park in London. You can spot deer just hanging out and plenty more interesting wildlife. I hear that David Attenborough lives in Richmond - which is clearly proof that it's the best spot for nature in the city.
If you're lucky and it's a sunny day, it's the best place to go for a picnic - Bushy Park is the second biggest park in London so there's plenty of space to find a quiet spot to yourself, or perhaps a fun tree to climb.
