The historic Dyfi Bridge (Pont ar Ddyfi) near Machynlleth dates back to 1805, following earlier timber and stone structures from 1533 and 1681. It served as the main A487 crossing until it was permanently closed to vehicles in February 2024 and replaced by a new £46 million modern viaduct upstream to prevent frequent flood closures.

Came up here on loaded up trail bikes. Absolutely stunning climb but would probably say best to take the parallel gravel path if on an offroad bike. A tourer with a granny gear or a road bike would have the most fun here. Two distinct sections, the bit leading up to the gate has long stretches of steep followed by stretches of 1-3%, and after the gate its stepped in 10-20% ramps. Think the steepest bit is just before the little waterfall.

A former slate village with a certain type of raw beauty, Corris is a little tourist honeypot. It is set within the Dyfi Forest and boasts a few attractions such as a craft centre, a centre for alternative technology, along with a narrow-gauge railway and museum. Ohhh did I mention bike trails? It has a never ending supply of them!
