People of all ages enjoyed boat trips, canoeing, paddle boarding and fishing. There was also live music, children's entertainment, displays, food and stalls.
The festival is now in its fifth year and aims to celebrate all the canal can offer the local community, with the Trust particularly keen to promote the benefits being by the water can have for people's mental and physical health.
Ros Daniels, Canal & River Trust's director, London and south east, says: "We're delighted so many people came down to the canal in Hayes to enjoy the festival. We couldn't run it without the support and passion of people from the local community, so a big thanks to everyone who contributed.
"The challenge now of course is to encourage those who visited the festival to come down to the canal more regularly. There is a huge array of things to do, whether that's paddle boarding or fishing, or using the towpath for a run, walk or to escape the busy streets.
"We know from research published recently that people are happier and more relaxed when they are by water, so getting out by the canal can have real benefits for your health and well-being. I'd encourage anyone to give it a try."
David Brough, Chairman of Hillingdon Canals Partnership, said: "The Hayes Canal Festival proves beyond doubt that whether you're on the water or on the land the canal can offer something for almost everyone. Sunday's event was a delight and it was great to see all sections of the diverse community of Hayes coming together to have fun."
The event was supported by Hillingdon Canals Partnership, Hayes Town Partnership, Inland Waterways Association, High Point Village and Hillingdon Community Trust.
