Afon Eden is a tributary of Afon Mawddach. It runs in a mainly southerly direction from Trawsfynydd to Y Ganllwyd where it joins the Mawddach. It is a spate river strewn with boulders and with a peaty stain to the water. The upper reaches have some deep pools as the river meanders slowly through the peat before increasing in speed towards the lower end.

There are some nice deep pools and glides which hold brown trout typically up to three quarters of a pound. There is a run of sewin and salmon towards the end of the season.

Please note that wading is not permitted as the river has the highest density of the endangered Freshwater Pearl Mussels found in Europe. Fishing from the bank is possible and relatively easy. The upper beat is fairly open while the lower beat is heavily wooded in places.
