The Ffestiniog runs through several miles of attractive terrain to Blaenau Ffestiniog. From Blaenau you can either proceed north on the standard gauge Conwy Valley Line to the coast at Llandudno or you can return to Porthmadog. A round trip (Porthmadog - Blaenau - Porthmadog) will take approximately 4 hours (more if you break the journey along the route) and it is therefore an excellent way of occupying a day.
The Ffestiniog Railway is a heritage railway based on 1 ft 11+1⁄2 in narrow-gauge, in Gwynedd, Wales. It is a major tourist attraction located mainly within the Snowdonia National Park.
