The Avenues conservation area is one of more than 20 protected parts of Hull, recognised for historical features and architectural character.
Among the visitors weaving their way through hidden paths are friends Emily Medcalf and Eleanor Sharpe, who pause to enjoy ice creams as they compare their favourite gardens.
“We’ve seen some lovely flowers,” Emily says, smiling.
“The highlight was one garden – it was really bright, with a lovely turquoise shed.”
Eleanor nods. “It’s lovely to see what everyone does with their garden, considering it’s in a small area.”
Across the road, Clare Hamilton, who lives nearby, sits on a patch of grass in front of a bush of purple lavender.
She comes every year.
Looking up, she says: “We love the Open Gardens, walking around, seeing all the beautiful flowers and sculptures.”
“It’s something really special to have in the community.”
