Wales Scenic Rail & Steam Coast
A car-free journey from Cardiff, traveling north along the Cambrian Coast Line and transferring to narrow-gauge steam trains to Conwy.
Relying entirely on mainline railways and narrow-gauge steam trains, this route winds from Cardiff via Shrewsbury to the west coast, heads north along Cardigan Bay, crosses the mountains to the Conwy Valley, and departs via Chester. The railways themselves are the highlight, but services are infrequent and transfers are many, requiring careful planning of timetables. Perfect for rail enthusiasts and car-free travelers; this route bypasses Pembrokeshire and the Gower Peninsula.
Narrow-gauge railways operate from around late March to October, and do not run full schedules every day.
