The original bridge, known as the 'lower bridge', is believed to date back to the 11th century and is locally attributed to the work of the Knights Hospitallers.
The water drop into the Mynach gorge totals approximately 90 meters across five major tiers.
The site was a frequent destination for 18th-century tourists, including William Wordsworth, who described the waterfalls in his poetry.
The geological formation consists of Lower Palaeozoic rocks, which have been deeply incised by glacial meltwater.
The temperate rainforest climate in the gorge supports high levels of biodiversity, including Atlantic bryophytes.
Devil's Bridge Waterfalls features a unique three-tiered bridge structure where three separate bridges were built on top of each other between the 11th and 20th centuries. The site showcases the confluence of the River Mynach and the River Rheidol, which drop 90 meters into the gorge. A steep nature trail with over 600 stone steps, known as Jacob's Ladder, provides access to the waterfalls and the base of the gorge. The Victorian bridge, constructed in 1908, sits directly above an 18th-century stone bridge and the original medieval arch. The surrounding temperate rainforest ecosystem is designated as a Site of Special Scientific Interest due to its rare moss and lichen communities. Visitors can observe the power of the cascading water from various platforms embedded into the steep canyon walls.

Wear sturdy hiking boots with aggressive tread, as the stone steps are frequently wet, slippery, and uneven.
Use the handrails provided throughout the descent, as the gradient is steep and physically demanding.
Carry a waterproof jacket regardless of the forecast, as the waterfall spray creates a localized microclimate.
Attempting the full circuit if you have mobility issues or limited physical fitness, as the return climb is strenuous.
The site is typically closed during the winter months and may close periodically during periods of extreme high water or severe weather.
Remain on designated paths to protect the fragile moss and lichen habitats; keep dogs on short leads.
