Hi,
This year there are two main Winter lights festivals in London.
New is the
Battersea winter lights which runs from Thursday 25th January to Sunday 25th February.
The perennial
Canary Wharf winter lights runs from Wednesday 17th January to Saturday 27th January.
I might be going to Canary Wharf on Friday 26th January and to Battersea on Friday 9th February, weather permitting. If anyone wants to tag along, just let me know.
