Must-Read about Notting Hill Carnival(狂欢节)

Route

The carnival procession itself begins at 9am on both Sunday and Monday. It starts on Great Western Road, winding its way along Chepstow Road, then on to Westbourne Grove, and then down Ladbroke Grove. See our Notting Hill Carnival map for the full route.

Bus 

While extra services will be in operation, no buses will enter the Carnival area from first thing Sunday morning until the first service on Tuesday morning. On both days bus services begin from Notting Hill Gate in the south and from Harrow Rd (close to Elgin Avenue) in the north.

Bike

Last year the nearest bike-parking stations – Chepstow Villas and Pembridge Road – were removed for Carnival, so don’t rely on being able to park your bike nearby this year.

Safety

Avoid carrying expensive items, such as jewellery and digital cameras. Take a bag with a secure zip to keep your more valuable possessions in and avoid putting your valuables in your back pocket. 

Do tell police if you see an incident. Officers will be stationed throughout the Carnival area. Don’t try to walk against the flow of the crowd, as you won’t get far. Drink plenty of water on the day too, especially if the sun makes an appearance.

Children

Children’s Day on Sunday is recommended for families as the smaller crowds and kid-friendly floats(游行花车) create a fun atmosphere. Arrange meeting points in case you become separated. The smaller the buggy(婴儿车), the better. Ear defenders may be necessary for very young children.
