A bit beyond the SE23 boundary, but if you find yourself at a loose end this weekend (24th/25th September) or next (1st/2nd October), around 70 artists are exhibiting at various locations in Catford.
There is lots of info on the Arts Trail website and you can download the full listings leaflet here.
We had a great turn out at no.19 where I was being hosted. No face-painting on offer, but still had tons of support from local residents!
I took part in the Sydenham Arts Trail a couple of years ago, and had the same experience as you @anon93536262. Forest Hill suffers a bit from being right on the edge of the Dulwich, Sydenham and Catford open house events unfortunately. We usually get a good turn out on Havelock Walk for the Dulwich event though, albeit with a fair amount of promotion ourselves locally…
This is going on next week too!
