The Ashdown Forest Clumps Challenge walk 2025

Join a guided walk around Ashdown Forest's 12 historic clumps!

You will be guided by a team from Ashdown Forest and The Ashdown Forest Foundation. Together we will raise funds for the Foundation in support of developing the next generation of aspiring young nature lovers and conservationists.

The challenge is in part inspired by former CEO James Adler, who successfully undertook the Clumps Challenge with his partner Jenny. James sadly died in 2023 at the age of 42. James was also a passionate advocate for supporting young people to come to know and love Ashdown Forest and the wider world of nature and conservation in general.

We will set off from Friends car park at 8am and – some 32km and 12 Clumps later – will finish back at the same spot by 6pm. We'll stop off for a well-earned lunch break at the Forest Centre in Wych Cross, where a much shorter “Mini Clumps Challenge” will take place throughout the day. More information about the mini challenge can be found here: https://ashdownforestfdn.org/2025/08/21/join-the-mini-clumps-challenge/

To take part in the main Clumps Challenge, please register in advance. Places cost £30 per person. Secure your place now at https://theashdownforestfoundation.beaconforms.com/form/81168d7d

If this looks too much of a physical challenge, you can still help us raise funds via Just Giving: https://theashdownforestfoundation.beaconforms.com/form/81168d7d

Help us smash the £3,000 target!
