More than 200 youngsters from across Havering will be taking part in the procession, which has been put together by arts company Emergency Exit Arts and the Grand Union Youth Orchestra.
Entitled 'Carnival to Silk Road', it will bring together hundreds of local people and will feature elements of world music, dance and design from Caribbean, Chinese, Indian and Eastern European cultures, culminating with a performance on the main stage.
Dancers and musicians from Abbs Cross and Frances Bardsley Schools will join the procession, as will primary school children and around 30 youngsters who took part in a summer carnival club at Fairkytes Arts Centre, where they prepared their carnival costumes and learnt music and dance routines.
