Walthamstow Marshes has received gold, the highest award, at this year's London in Bloom Awards.
The marshes are one of six Lee Valley Regional Park sites to win gold this year. Sites have to score 85% or more in their assessments to get the top award. The 2026 results mean all six sites have held gold status for a decade.
Shaun Dawson, chief executive of Lee Valley Regional Park Authority, said: "These awards are a fitting tribute to the staff and volunteers at Lee Valley Regional Park Authority who work tirelessly to maintain these important sites."
He also pointed to how varied the park's landscapes are. He described one site as "a hidden gem in urban East London, a former industrial site which is now a haven for wildlife". The other was a large country park, once used for munitions testing, that now has walking trails, cycle paths and a range of habitats.
This is the latest in a run of recognition for the park authority. In July it received ten Green Flag Awards, including one for Queen Elizabeth Olympic Park, which it manages jointly with the London Legacy Development Corporation. Myddelton House Gardens in Enfield has also kept its Green Heritage Site Accreditation, which recognises how historic features are managed and promoted, with support from Historic England.
Lee Valley Regional Park's spaces are free to visit all year round. They cover thousands of acres that can be explored on foot, by bike or on the water.
