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.

My favourite descent of the whole Trans Cambrian route. We did it in June, during a very dry spell. It was epic fun, with huge pink flowers all the way down, wonderful trees and the babbling river topping off the whole sensory experience. Heaven.
