Hafod Elwy Moor National Nature Reserve, located in the moorland above the town of Denbigh in Denbighshire, North Wales, is part of the Mynydd Hiraethog Site of Special Scientific Interest, formerly managed by the Countryside Council for Wales and now under the jurisdiction of Natural Resources Wales. Established in 1999, it comprises an 82-hectare (200-acre) patch of upland moor lying between the lakes of Llyn Brenig and Llyn Alwen. A conifer forest planted by the Forestry Commission borders the moor to the south and east.With plant life dominated by heather and bilberry, the reserve provides important habitat for ground-nesting birds. Birds found in the area include the Northern wheatear, and some black grouse. The reserve is classified as a Category IV site by the International Union for Conservation of Nature, meaning that the area regularly needs active interventions to support particular species. Conservation efforts focus on increasing black grouse populations. In addition to these ground-nesting birds, the reserve is home to merlins and other small birds of prey such as peregrine falcons, kestrels, and hen harriers.The reserve is open to the public, but has no facilities; except for one bridle path, it is difficult to traverse on foot. The nearest roads are the A543 and the B4501, with access via the Brenig Visitor Centre off the B4501.The name "Hafod Elwy" references a hafod, or Welsh summer farmhouse. According to local folktales, captured in a ballad, Hafod Elwy was home to a man named Ffowc Owen in the 1770s, who could not marry his true love and froze to death on the moor. A memorial cairn for Owen is said to be present on the moor.

The Denbigh Moors (Welsh: Mynydd Hiraethog) are an upland region in Conwy and Denbighshire in the north of Wales, between Snowdonia and the Clwydian Range. It includes the large reservoirs Llyn Brenig and Llyn Alwen, and the Clocaenog Forest, which has one of Wales's last populations of red squirrels. It also contains the open heath Hafod Elwy Moor National Nature Reserve. Its highest point is Mwdwl-eithin, at 532 metres (1,745 ft) above sea level, making it higher than Exmoor. Another summit is Moel Seisiog, at 467 metres (1,532 ft), which is also the source of the River Elwy (53°05′N 3°42′W). On its western edge, overlooking the Conwy Valley, lies the Moel Maelogan wind farm. Three other summits reach over 500 metres – Craig Bron-banog (502 metres), Gorsedd Bran (518 metres), and Foel Goch (Marial Gwyn) (519 metres). The ruined hunting lodge of Gwylfa Hiraethog (known locally as Plas Pren due to its original timber construction) lies at a height of 498 metres (1633 feet). Built by the grocery tycoon Hudson Kearley lies on the moors, and nearby is one of the highest inns in Britain, the Sportsmans Arms. As well as the large reservoirs of Llyn Brenig and Alwen Reservoir there are two sizeable natural lakes – Llyn Alwen and Llyn Aled, and two small ones, Llyn Bran and Llyn y Foel-frech – as well as another reservoir, Aled Isaf Reservoir (lower Aled Reservoir).

The Clocaenog Forest is in west Denbighshire and east Conwy, Wales on Mynydd Hiraethog. It takes its name from the village of Clocaenog, near Ruthin.

Nantglyn is a small village and community in Denbighshire, Wales. The population of the community taken at the 2011 census was 323. It is situated in a rural location about 4.5 miles (7.2 km) away from the nearest town, Denbigh. Nantglyn is located on a small river, the Lliwen.

Brynbach was a National Campsite of the Scout Association, situated near Saron in Denbighshire in North Wales. The 200-acre site had its heyday between the 1930s and the late 1950s. It had naturalistic wooden entrance gates designed by Lord Baden Powell, the founder of Scouting.The camp had a summer-house (later moved to Gilwell Park), a 1 m (3 ft 3 in) deep boating lake, and a spring-filled swimming pool. An outline of the Fleur de Lys, the Scouting emblem, was created by planting Golden Larch trees in the surrounding woods.

Mwdwl-eithin (532 metres (1,745 ft)) is the highest point on the Denbigh Moors (Welsh: Mynydd Hiraethog) of North Wales. This gently rising mountain lies about 10 miles (16 km) east of Betws-y-Coed. On its summit is a trig point and a ruined building which still provides shelter against a storm. A few metres away is a large raised stone cairn. The whole area is underlain by Silurian mudstone which was extensively glaciated during the last British glaciation. The whole area is now very wet moorland dominated by heather (Calluna and Erica spp.) and rushes. Three of the surrounding valleys and depressions have been used for drinking water storage reservoirs, Llyn Alwen, Llyn Aled and Alwen Reservoir.

Llyn Aled is a lake on Mynydd Hiraethog in the Conwy County Borough. It is situated north of the A543 and 7 kilometres (4.3 mi) to the north-east of the village of Pentrefoelas. It is a natural lake; however, a dam was built at its northern outlet to increase its size. It has an area of 112.7 ares (1.127 ha) and is 1,227 feet (374 m) above sea level. One can reach the lake via the A543. There are a number of varieties of fish in the lake, including pike. The lake was used by the Llyn Aled Sailing Club (Clwb Hwylio Llyn Aled), but the club closed down due to a dwindling membership and the proximity of the much larger Llyn Brenig. The Clwydian Way runs along the north side of the lake. Llyn Aled feeds the Llyn Aled Isaf reservoir. The lake is also the source of the River Aled, which flows northward.
