Coed Cymerau National Nature Reserve

Dduallt railway station (English: Black hill) (pronounced [ˈðɨ.aɬt]) is a passenger station on the narrow gauge Ffestiniog Railway in northwest Wales, which was built in 1836 to carry dressed slate from Blaenau Ffestiniog to Porthmadog for export by sea. Dduallt is at a height of 540 feet (160 m) and a distance of just over 9.5 miles (15.3 km) from Porthmadog.

The River Dwyryd (Welsh: Afon Dwyryd, meaning a river of two fords, is a river in Gwynedd, Wales which flows principally westwards; draining to the sea into Tremadog Bay, south of Porthmadog.

Coedydd Maentwrog, on the north side of the Vale of Ffestiniog, is the largest wood in the Vale (which runs from the coast at Porthmadog inland to Blaenau Ffestiniog in Gwynedd). The national nature reserve consists of two separate sections: Coed Llyn Mair, and a group of three forests (Coed Ty Coch, Coed Bronturnor and Coed Glanrafon). It offers a variety of habitats, rising from the wooded valley onto open moorland and reaching towards the foot of Moelwyn Bach mountain. A nature trail and a network of public footpaths (some of which are steep and slippery when wet) are features of the reserve. Animals such as the rare lesser horseshoe bat and the wood warbler can be spotted here, and the gorge is noted for its liverworts and lichens. The reserve is located near Maentwrog, and is accessible by car via the A487. It may also be reached year-round by bus and by train from Easter to November, with occasional service during Christmastime and school holidays.

Moelwyn quarry is a defunct slate quarry located to the south of the village of Tanygrisiau, north Wales. Some initial prospecting was carried out in the 1820s and again in the 1840s, but it was 1860 before a company was formed, and chambers were excavated. The quarry was never a financial success, and operated sporadically until its demise in 1897. Despite the poor results, a spectacular series of seven inclines were constructed, to enable slates to reach the Ffestiniog Railway. The quarry was hampered by lack of a good water supply, and the mill was constructed between inclines 4 and 5, where water could be obtained from Llyn Stwlan. As in many quarries, barracks were provided, but these were occupied by whole families, living on the mountain, rather than used as lodgings for the quarrymen during the working week. Even in its remote location, there was still a concern for education, with basic literacy classes being run in the 1860s.

The Ffestiniog Power Station (Welsh pronunciation) is a 360-megawatt (MW) pumped-storage hydroelectricity scheme near Ffestiniog, in Gwynedd, north-west Wales. The power station at the lower reservoir has four water turbines, which can generate at full capacity within 60 seconds of the need arising. The scheme has a storage capacity of around 1.44 GWh (5.2 TJ) at maximum output for four hours, and the capacity to power the whole of North Wales for several hours.The station, commissioned in 1963, was the first major pumped storage system in the UK. The upper reservoir is Llyn Stwlan, 170,000 cubic metres (6,000,000 cu ft), which discharges 27 cubic metres per second (950 cu ft/s) of water to the turbine generators at the power station on the bank of Tanygrisiau reservoir. The building of the lower reservoir increased the size of Llyn Ystradau and flooded the route of the Ffestiniog Railway which had to build a deviation around the reservoir and power station. The plant is operated by First Hydro, a UK company owned by a joint venture of International Power and Mitsui & Co., and has an average efficiency of 72–73%, i.e. it uses 39% more electricity (when pumping the water back up to the Llyn Stwlan) than it actually produces.

Tanygrisiau railway station (grid reference SH683449) is a passenger station on the narrow gauge Ffestiniog Railway The line was built in 1836 to carry dressed slate from Blaenau Ffestiniog to Porthmadog for export by sea but official passenger services began in 1865. The station serves the slate mining village of Tanygrisiau and was opened in March 1866. It closed to passengers on 15 September 1939. The new station opened for passenger traffic on 24 June 1978 and was the passenger terminus until 25 May 1982. Tanygrisiau station is at a height of 669 ft (204 m) and a distance of 12 miles 10 chains (19.5 km) from Porthmadog. The new station is on a different alignment and grade from the old, the two alignments joining just to the north of the Blaenau end of the station. The old line was on a continuous downward gradient from that point through the station, but the new line is on an uphill gradient (to pass the nearby power station) and is more sharply curved. One of the old buildings still remains, visibly lower than the new trackbed. Tanygrisiau station has an operational passing loop but is normally operated as an unstaffed halt and trains only call on request. Intending passengers are advised to check with the Ffestiniog Railway Company before embarking on their journey. The station is close to the Cwmorthin water falls, and the train passes Tanygrisiau hydro-electric pumped-storage power station and Llyn Ystradau.

Campbell's Platform (grid reference SH673418) is a private, unstaffed halt on the Welsh narrow gauge Ffestiniog Railway, which was built in 1836 to carry dressed slate from Blaenau Ffestiniog to Porthmadog for export by sea. It is 9 miles and 7 chains from Porthmadog and is at 510 feet above sea level.
