Walthamstow is very luck to have some fantastic open spaces, parks, and forests. Here I’ve listed my favourites, but why not go exploring and see what you can find.

St James Park was my local childhood play area. During school holidays Lloyd’s Park theatre entertained hundreds of us. I have started visiting E17 again in recent years and am delighted the two parks still exist and hold the same attractions as back in the 1950s.
