Lovely woodland walk, can be a bit boggy in places. The dog absolutely loved it. Little streams for the dog to splash in.

Ruperra Castle was built in 1626 by the Steward to the Earl of Pembroke, Sir Thomas Morgan. It's actually a mock castle – a residence with a castle-like appearance rather than a fortress. Now, the castle lies in ruin and is quite something to behold.

St John's church in Machen is easy to spot as you hike past thanks to its distinctive spire. The church was built in the mid-1800s when the local population swelled in response to industrialisation. It's still an active community today, and has some interesting features.
