Day out in London

[FrkBrum]

I'm staying in London for a couple of days next week, and wednesday will be dedicated to relaxed caching in the sun (!). Can anyone recommend a park for the day? Looking at Hampstead Heath, Richmond Park, Holland Park, I don't know which to choose.
If anyone want to join in, that's great.

If it matters: female, late fifties body, very young soul

If you're looking for parks with caches in them then there's not a lot of choice as the Royal Parks won't have them, so Richmond Park is a caching desert (and it's quite a way out of London). Holland Park and Hampstead Heath is about all you have to choose from, and I've never been to either so can't comment
