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 prominent landmark in the centre of Machynlleth, the Clock Tower was built in 1874 to mark the coming of age of the eldest son of the Fifth Marquess of Londonderry. It marks the southern termination of the Snowdonia Way long-distance trail. For supplies, there are plenty of places to stock up in the town.
