Introduction

Ashdown Forest is not known for permanent waterfalls, but after prolonged rain the landscape briefly transforms. Beneath the open heathland plateau, sandstone ledges and clay layers shed water quickly, feeding short-lived streams that cut into wooded ravines and momentarily bring hidden waterfalls to life. Miss the timing and these features disappear again, leaving little trace beyond damp rock and leaf-stained pools.

This walk followed one such stream after heavy December rainfall, linking three very different waterfalls: the hidden plunge of Mungo’s, the stepped Garden of Eden fall beside a footpath, and an unnamed woodland drop further downstream. Each only flows properly for a short window after rain, making timing far more important than season or popularity.

The short video below captures all three waterfalls in motion, followed by mapped references for context. The sections that follow look at each waterfall in turn, combining the walk itself with notes on geology, nature, and what makes these fleeting moments worth photographing in Ashdown Forest.
