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.

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.

Coed Cymerau National Nature Reserve is a wooded area of approximately 26 hectares on the north side of the Vale of Ffestiniog through which the River Goedol runs. There is one path that runs through the forest but the rest of the area is primarily native broadleaved woodland and thick undergrowth, adjacent to the nature reserve is Coed Cymerau Isaf which is owned by the Woodland Trust.

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.

Ceunant Llennyrch National Nature Reserve is one of several woodland reserves in the Vale of Ffestiniog in Gwynedd, Wales and runs from Llyn Trawsfynydd to the River Dwyryd, near the village of Maentwrog. The reserve's broad expanse of woodland coats a steep-sided gorge, through which the Afon Prysor cascades. At one point, the river is flanked by one hundred feet (30 m) high cliffs, which face each other only 10 metres (33 feet) apart. The high humidity offered by the falls creates the perfect environment for numerous damp-loving plants, due to the high humidity and high rainfall, it is technically a temperate rainforest.

Gellilydan () is a village in the Welsh county of Gwynedd, in Maentwrog community. It lies 4 miles (6.4 km) south-south-east of Blaenau Ffestiniog. The village has a local pub by the name of Bryn Arms which was built by two brothers, Ellis and Norman Richards, who named the pub after their father.

Maentwrog () is a village and community in the Welsh county of Merionethshire (now part of Gwynedd), lying in the Vale of Ffestiniog just below Blaenau Ffestiniog, within the Snowdonia National Park. The River Dwyryd runs alongside the village. Its population of 585 in 2001 increased to 631 at the 2011 Census. The Community of Maentwrog includes the village of Gellilydan.

Saint Twrog's Church is in the village of Maentwrog in the Welsh county of Gwynedd, lying in the Vale of Ffestiniog, within the Snowdonia National Park. It is in the Deanery of Ardudwy. It is designated by Cadw as a Grade II listed building.A church was founded on the current site in the 6th century by Saint Twrog. It is believed that he was the son of Ithel Hael o Lydaw of Brittany. He was also the brother of Saint Tanwg of Llandanwg, Saint Tegai of Llandygai and Saint Baglan of Llanfaglan and Baglan.There are two other dedications to Saint Twrog: at Bodwrog in Anglesey and at Llandwrog. When Twrog first arrived in the village, the valley would have been very marshy, which provided him with the wattle that he would have needed to build his cell. Out the church near to the belfry door is a large stone known as Maen Twrog (maen being the Welsh for stone). Twrog is reputed to have thrown the stone from the top of Moelwyn crushing a pagan altar in the valley below; it is said that his handprints can still be seen in the stone. The parish of Maentwrog gets its name from this stoneThe yew trees in the churchyard are said to be over 1300 years old. They were a feature of the ancient pagan burial places, their evergreen leaves being a symbol of immortality; however, 1300 years ago the site would have been Christian not pagan. Another use of the yew trees was for military purposes as the yew timber was excellent for making bows, but because of the poisonous nature of the yew trees they were not popular among the people and were therefore grown in relative safety in places such as churchyards. The church that was on the site before 1896 was dedicated to Saint Mary, which has a connection to the Cistercian monks who were very numerous in the Maentwrog valley at one time. In the village there is also Saint Mary's well and across the valley is Llyn Mair (Saint Mary's Lake). In 1504, the church was described as a chapelry attached to the extensive parish of Ffestiniog. During the years 1572 to 1624, the notable Edmwnd Prys was rector of the church. He translated the metrical psalms into Welsh, and the present west window commemorates his work.The church was rebuilt in 1814 on the old foundations and was described as a neat stone edifice and was rectangular with a square embattled tower. There was no chancel at that time, the altar being placed in front of the present altar rails, with the door and porch being on the north side. On the west wall of the church there were three small windows. In 1896 a new chancel was built along with a baptistery and new stained glass windows were installed consisting of the east and west windows and the small "Good Shepherd" window. The vestry window "Son of Consolation" is in memory of William Edward Oakeley, benefactor of the parish, with whose help the church was restored in 1896, his wife Mary Oakeley executed the beautiful carvings. During this alteration, the bell was replaced by an eight tubular bells and the present organ was installed at the same time. The old bell was installed in the village school tower. The architect responsible for the alteration work to the church in 1896 was John Douglas who was also responsible for the design of the lych gate. There are some memorials on the north side of the church and on both sides of the altar which were transferred from the 1814 church, and there is a carving of Saint Twrog on the pulpit. A fragment of Edmwnd Prys' pulpit also remains. The parish register goes back to 1695. Outside in the graveyard are three Celtic Cross style memorials to members of the Oakeley family. There is also a very old attractive church entrance gate which opens on the main road in Maentwrog.

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.
