The Nod Glas Formation (also known as the Nod Glas Black Shale, the Cadnant Shale, the Penarwel Mudstones or just Nod Glas) is an Ordovician lithostratigraphic group (a sequence of rock strata) in Mid Wales. The rock of the formation is made up of pyritous, graptolitic mudstone that is generally black in colour. It weathers to a soft, very well cleaved and coal-like material. The formation runs from Conwy in the north, down to Cardigan Bay in the area around Aberdyfi and Tywyn, though it is not a continuous over this area.The formation is the topmost of the Caradoc Series in North Wales, and the name refers to all the black shale beds in the area. In South Wales, the equivalent beds of shale are called the Dicranograptus Shales.

Coed Dolgarrog National Nature Reserve is a nature reserve which covers the steep western side of the Conwy Valley, outside the village of Dolgarrog, around 10 kilometres south of Conwy and 6.5 kilometres north of Llanrwst in Conwy County Borough, Wales.

The Cedryn Quarry Tramway (later largely used as the route of the Eigiau Tramway) was an industrial narrow gauge railway that connected the slate quarries at Cedryn and Cwm Eigiau to the quays at Dolgarrog in the Conwy valley.

Dolgarrog railway station is an unstaffed halt, and a request stop, on the Conwy Valley Line from Llandudno Junction to Blaenau Ffestiniog. The station is located on the east bank of the River Conwy just across the A470 road from Plas Maenan, which was the home of Henry Jack, the Managing Director of the Aluminium Corporation from 1916 to 1927, together with its associated enterprises including the Ffestiniog Railway and the Welsh Highland Railway. Plas Maenan is now a small country house hotel and restaurant with views across the valley.

The Eigiau Tramway might refer to the Eigiau Quarry Tramway or to the Eigiau Reservoir Tramway.

Adventure Parc Snowdonia, formerly Surf Snowdonia is an adventure park and tourist attraction, incorporating an artificial wave pool, at Dolgarrog in the picturesque Conwy valley, north Wales, owned by Conwy Adventure Leisure Ltd.

Dolgarrog Power Station in Dolgarrog, Wales was originally built in 1907 as part of an aluminium smelting plant. It uses water turbines to drive electricity alternators. Public supplies began in 1922 when power lines were constructed to transmit electricity from the power station to Colwyn Bay, Conwy and Llandudno. The station was vested in the British Electricity Authority and its successors following nationalisation in 1948. It is currently (2021) operated by RWE NPower UK.

Dolgarrog is a village and community in Conwy County Borough, in Wales, situated between Llanrwst and Conwy, very close to the Conwy River. The village is well known for its industrial history since the 18th century and the Eigiau dam disaster, which occurred in 1925. The population was 414 at the 2001 Census, increasing to 446 at the 2011 Census. The community extends up to, and includes part of, Llyn Cowlyd in the Carneddau. The village is served by Dolgarrog railway station, a halt on the other side of the river Conwy, The bridge allowing access to the station was slated for closure in 2021 due to it being structurally unsafe, but reopened after repairs in 2023.Surf Snowdonia, the world's first commercial artificial surfing lake, is located in Dolgarrog on the site of the old aluminium factory. Across the valley is the crag of Cadair Ifan Goch.

Afon Porth-llwyd is a river in Snowdonia in north-west Wales. It flows from Llyn Eigiau on the south-eastern edge of the Carneddau range to join the river Conwy. Its waters are trapped at Coedty reservoir before flowing down to pass under Pont Newydd in Dolgarrog. From Coedty reservoir some water is also diverted to Dolgarrog Power station (along with water from Llyn Cowlyd) via large black pipes.

Cadair Ifan Goch (Chair of Ifan Goch, the Giant) is a crag located above the Conwy Valley in North Wales in the community of Llanddoged and Maenan, and owned by the National Trust. The views extend across the whole of the valley to the Carneddau mountains, and even as far south as the Arenig mountains. The summit of the hill, a bit further up from the crag, reaches 207 metres (679 ft) above sea level. According to legend, Ifan Goch the giant sat on this ledge to cool his feet in the river Conwy below. Another version tells how he is alleged to stand with one foot on Cadair Ifan Goch on one side of the valley, and the other on Pen-y-Gaer on the opposite side of the valley in order to wash his face in the river.

Afon Dulyn (English : River Dulyn) is the outflow from Llyn Dulyn, a lake in the Carneddau mountains in north-west Wales. It is a tributary of the river Conwy. Just below Afon Dulyn the river is joined by Afon Melynllyn, a small river flowing from neighbouring Llyn Melynllyn. The river does not carry a great deal of water because water is transferred from Llyn Dulyn to the reservoirs of Llyn Eigiau and Llyn Cowlyd.

Tal-y-Bont is a small village in Conwy County Borough, Wales and lies in the Conwy Valley, west of the River Conwy, on the B5106 road, 6 mi (9.7 km) from the town of Conwy to the north, and six miles from Llanrwst to the south, and in the community of Caerhun. It lies adjacent to the village of Dolgarrog to the south, and below the small settlement of Llanbedr-y-Cennin to the west. The population is around 400. The 'Bont' (the mutated form of pont, Welsh for "bridge") in the name probably refers to the bridge over the Afon Dulyn, a tributary of the nearby River Conwy, which runs through the village. The village is served by buses and the nearby Dolgarrog railway station. Castell, the oldest section of Tal-y-Bont, has a bar/restaurant and a 5-acre garden centre. The village also has a shop and post office and a café, formerly Y Bedol Pub.
