Dinas Oleu Walk, Barmouth, Snowdonia
Climbs steeply uphill from Barmouth through woodland and rocky sections to panoramic viewpoints over Cardigan Bay and the Mawddach Estuary. The gradient makes this unsuitable for buggies and challenging for young children, though fit families will manage the short distance. Dogs welcome on leads. Dinas Oleu was the National Trust's very first property, and the clifftop views reward the effort—stunning sunsets and sweeping coastal vistas make this a local favourite.
