The Fairy Glen is a site of special scientific interest due to its unique bryophyte flora, specifically rare mosses and liverworts.
The river that forms the gorge, the Conwy, is known for its dramatic changes in water level following rainfall, which can significantly alter the appearance of the falls.
The gorge acts as a microclimate, remaining notably cooler and more humid than the surrounding Betws-y-Coed area.
Despite its proximity to the village, the narrowness of the gorge creates an acoustic environment that muffles outside traffic noise.
Ffos Anoddun, commonly known as the Fairy Glen, is a secluded, steep-sided wooded gorge carved by the River Conwy in North Wales. The site features a series of cascading falls and pools nestled within a dense canopy of mossy trees and fern-covered rock faces. A network of rough, natural paths traverses the ravine floor and slopes, offering varying vantage points of the river's turbulent flow. The gorge is privately owned and requires an entry fee, which is collected via a turnstile system at the entrance. The geological composition is primarily rock formations typical of the Conwy Valley's rugged topography.

Wear footwear with high-traction soles as the paths and wooden stairs become extremely slippery when wet.
Bring small coins or a contactless card, as the entrance turnstile is automated and requires payment to gain access.
Use an insect repellent during summer months to manage midges, which congregate in the damp, shaded valley.
Do not visit during or immediately after heavy rainfall as the paths can become flooded and the river current hazardous.
Stay on marked trails to protect the fragile moss and fern ecosystem; do not attempt to swim in the river due to dangerous currents.
