If you want to encounter witches and warlocks, spirits and spectres, then our October open day is the time to put on your spookiest  costume and head for London's oldest allotments. There, as darkness descends, you can follow our Halloween pumpkin trail, all eerily lit with Jack-O-Lanterns.

Those wishing to get into the spirit will also find a barbecue, a bar serving beer and mulled wine, and tea and cakes. Entry is free.
