Hi,
The next outing is a walk around the St James area, I have a more detailed plan but it covers this area:

A few ideas would be borrowed from
https://mylondonwalks.com/walks/a-walk-through-st-jamess/ but we wander whereever we want to.
There are no Orpington trains on Sunday 9th July, hence the date. Would meet at Charing Cross Station around 10:00am.
