Cavern Cascade

Cavern Cascade is a waterfall and a romantic, partly man-made grotto on the Hafod estate in Ceredigion, mid Wales. It belongs to the landscape that Thomas Johnes laid out in the late 18th century for visitors who loved picturesque scenery. Welsh heritage records list it as a post-medieval folly, and it also appears under the name Hafod Uchtryd Cavern Cascade.

What is Cavern Cascade?

The effect was staged like a piece of theatre. A mining-style adit was driven through the rock below the falls, forming a grotto, so walkers watch the stream tumble past from inside the cliff. Such tricks suited an age that treated wild nature as art and routed its walks to deliver surprises. A local name for the spot, Lefel Lampwll, refers to the level, or adit, which fits the tunnel's origins.

Where is it?

The cascade lies roughly 1.5 km from the site of Hafod mansion, deep in a wooded valley. The nearest village with visitor facilities is Devil's Bridge (Pontarfynach), a few kilometres away. Coordinates are about 52.339 N, 3.800 W.

What else is nearby?

The Hafod estate is known for woodland walking routes that follow paths first laid out in Johnes's day. A walk to the cascade combines easily with other viewpoints and traces of the old estate. Devil's Bridge itself is known for three bridges stacked one above another across a waterfall gorge.

When should you visit?

Spring, early summer and the days after rain show the stream at its fullest. Forest paths can be muddy, so wear proper walking boots. In winter the days are short and stone steps may be slippery.

How should you prepare?

Carry a map or offline route, as phone signal in the valley can be poor. Check current access information for the estate's trails before you travel.
