As one of three tributaries to the River Ruel, Alt a Chaol Ghleann passes 15m below the parapet of Dunans Bridge, swirls around the skirts of the tallest tree in the UK and pelts down a broad rock-strewn ravine, one side of which is owned by the proprietors of Dunans. With three fishing pools on this short stretch, including the one that until recently held the record for producing the Ruel’s heaviest Salmon, a canopy of native woodland stretching some hundreds of feet above, and a dramatic hidden, almost tropical microclimate, the visitor feels transported into an extraordinary, water-suffused enclave.

As Laird or Lady of Dunans Castle you’ll have free access to the ravine on the Dunans side, along with access to fishing rights by appointment with the proprietors.
