Tree Festival returns to Sussex for summer 2026

Celebration of the beauty, value and impact of trees offers a host of events for everyone to enjoy.

The programme for the 2026 Tree Festival – a celebration of trees in Sussex – has been revealed.

A fantastic selection of events will be taking place in May and June. Highlights include a family-friendly talk and walk with renowned Sussex naturalist Michael Blencowe, a Forest School taster session in Steyning and our Tribute to the Trees event in Preston Park, Brighton.

CPRE Sussex director Paul Steedman said: “We are thrilled to once again offer everyone living in Sussex the opportunity to celebrate the wonderful trees we have on our doorstep. Trees are more than just beautiful – they provide shelter for wildlife, they help to slow climate change, and they boost our health and wellbeing. I hope everyone will join us for this year’s exciting programme of events.”

This year’s programme includes guided walks, storytelling and creative workshops. There will also be exhibitions at Worthing Museum and Hastings Museum and Art Gallery – plus the return of our I Love This Tree Because…photo competition.
