Hiking around Hafod Elwy Moor National Nature Reserve explores a large expanse of upland heather moorland in Denbighshire, North Wales. The landscape is situated between the Llyn Brenig and Llyn Alwen reservoirs, characterized by open moor, areas of heathland, and acid bog. A public bridleway crosses the reserve, and several shared-use trails begin from nearby reservoir car parks.

You can head back to llyn brenig before you get to the section as a short cut, this but is not to be missed. Flows really nice, cutting through some old forest before a fun section along the lake.

Though it was not a tough or technical ride, it did take me into territory I had never visited before and was a lovely antidote to the 'fleshpots' of Gwydir Forest or Coed-y-Brenin. Some lovely gentle singletrack, beautiful views and I didn't see another rider for the whole trip - although tbh I did set off at 08.30 on a Wednesday!!

Alwen Reservoir is the largest human-made lake in Wales and it makes for a lovely walk. There's a car park at its eastern end and the 6-mile (10 km) loop of the reservoir is wonderfully scenic and suitable for the whole family. The mixture of lake views, woodland and open moorland make it a real treat.

This bridge across the 900-acre (364 ha) Alwen Reservoir enables a beautiful and tranquil loop of the Wales' largest artificial lake. The views across the water and to the surrounding woodland and hills are lovely.

The grand, ornate stone dam of Alwen Reservoir couldn't be more of a contrast to the neighbouring Llyn Brenig Dam. It's well worth taking a minute or two to take in this magnificent feat of engineering, that was completed in 1920. The reservoir here was built to provide drinking water for Liverpool and the Wirral.

The trails range from easy to difficult, offering something for most abilities. You'll find short, relatively flat walks like the 3.2-mile (5.1 km) Alwen Dam loop from Rhydlydan, as well as more challenging, longer routes across the moorland. Most hikes are graded as moderate, involving some elevation gain and mixed terrain.
Yes, many of the best routes in the area are loops. A great moderate option is the Alwen Dam – Alwen Reservoir loop from Rhydlydan, which is a 4.6-mile (7.4 km) circuit. For a longer day out, the 14-mile (22.7 km) Two Lakes Trail also offers a fantastic circular journey through the landscape.
Yes, dogs are welcome, but they must be kept on a lead at all times. This is crucial to protect ground-nesting birds, such as the rare red and black grouse that inhabit the moor, and for the safety of grazing livestock.
The main access points with parking are the Llyn Brenig Visitor Centre and the Alwen Reservoir car park. Both serve as excellent starting points for many of the waymarked trails that explore the reserve and the surrounding reservoirs.
Yes, the area is suitable for families. The shared-use trails starting from the Llyn Brenig Visitor Centre are generally well-maintained. The shorter paths around the reservoirs, away from the most rugged moorland, are good options for those with younger children.
The terrain is primarily upland heather moorland, which can be wild and rugged. Expect a mix of well-defined bridleways, grassy paths, and some boggy sections, especially after rain. It's a vast, open landscape, so be prepared for exposure to the elements. Proper waterproof hiking boots are essential.
Hafod Elwy is a key habitat for birdlife. Keep an eye out for skylarks, kestrels, and merlins. The reserve is one of the last places in Wales to see both red and black grouse. In the boggy areas, you might also spot interesting plants like sundew and butterwort.
To see the moorland transformed with vibrant pink and purple colours, plan your visit for late summer, typically in August and early September. This is when the common heather and bell heather are in full bloom, creating a spectacular display.
There are no facilities within the nature reserve itself. However, the Llyn Brenig Visitor Centre has a café where you can get refreshments before or after your hike. For pubs and other options, you would need to drive to nearby villages like Cerrigydrudion or Rhydlydan.
The reserve is a natural, wild space with no facilities on the moor itself. The nearby Llyn Brenig Visitor Centre provides public toilets, a café, and information about the area. It's best to arrive self-sufficient with all the food, water, and gear you'll need for your hike.
The trails around Hafod Elwy Moor are highly rated by the komoot community, with an average score of 4.5 stars. Hikers often praise the vast, open scenery, the sense of wildness, and the well-marked paths around the reservoirs.
Yes, according to local folklore, a memorial cairn on the moor marks the spot where a man named Ffowc Owen froze to death in the 1770s. The story goes that he was heartbroken after being forbidden from marrying his true love.
