The UK's largest free celebration of the natural world will return to Bristol, Bath and online from 6-14 June 2026.

In 2026, we’re putting trees and forests at the heart of the festival!

So much of our natural world revolves around them – they protect our wildlife, slow climate change and provide endless health benefits. This year, we’ll be shining a spotlight on everything trees do for us, and how they link to our waterways, food, and communities in ways you might not expect.

Get your hands in the soil, explore the world of woodland creatures, get up close on a tree trail, learn something new in an expert talk or get inspired by an immersive screening… Look out for our full programme announced in April to discover nature near you.
