To keep the Dell safe, welcoming and enjoyable for everyone, please follow our community guidelines:
While we want all visitors to enjoy the park, events or large gatherings are not permitted. This includes parties, picnics of more than a few people, or any activity involving:
tables, chairs or gazebos
decorations such as balloons
amplified music or entertainment
If you wish to hold an event in the Dell, you must obtain permission from Brent Council and secure any necessary licences required for health and safety compliance:
Email: parks.service@brent.gov.uk
Please remember that the Dell is a small pocket park; larger gatherings can unintentionally make regular visitors feel excluded. For bigger celebrations, consider local parks better suited to events, such as Kilburn Grange Park, Queen’s Park, Gladstone Park, or Roundwood Park.
Mapesbury Dell is a family-focused park, visited mostly by children and their carers.
We therefore kindly ask that you do not consume alcohol in the park, except during official Dell events organised by the Mapesbury Dell Trust, where the correct permissions have been obtained.
Because of the park’s size, ball games—especially football—can be unsafe for younger children and can damage our carefully maintained gardens and lawns.
Please help us protect the space by encouraging children not to play football during busy times or when requested. We rely on the good judgment and consideration of our visitors.
We love dogs at the Dell! Please keep them on a lead at all times and ensure that all waste is properly disposed of to keep the park safe and clean for everyone.
