Start fundraising
The Ashdown Forest Foundation is the official fundraising charity of Ashdown Forest, one of the largest open access areas in South East England. Without your help, Ashdown Forest as we know and love it will not survive. Please help us preserve this beautiful Forest for all, for the future.

Story

Nature in the UK is in crisis. The ongoing and serious loss of biodiversity and habitats nationwide is having a huge impact on our environment and wellbeing.

But you have a chance to make a difference. Ashdown Forest is a unique and precious landscape supporting a diverse range of rare and protected species. With your support, the Forest can thrive and remain a haven for wildlife.

Challenge yourself to a 32km guided walk taking in the Forest's historic clumps of pine trees, and help us to raise funds to inspire the next generation of young nature lovers and conservationists. The main walk starts at Friends Clump at 8am on Saturday 27th September.

The Mini Clumps Challenge

Families can join in too, in a 3km walk where you can learn about the Forest and why it is so important for our national environment. Join us at the Ashdown Forest Centre between 11am and 4pm on Saturday 27th September to take part!

Make sure to register

Register here to secure your exclusive place. Only 30 places are available for the main walk; and we also encourage families to register in advance for the mini challenge.

Your fundraising will help us to work with local schools, support our Youth Rangers to make an impact, and encourage children and young people to take care of nature for the future.

Fundraise for us today to become a part of our story, and help save Ashdown Forest for tomorrow.
