The Sunken Road (View of Claerwen Dam) is situated in the remote Claerwen Valley, approximately ten miles southwest of Rhayader in Powys, Wales. It offers commanding views of the Claerwen Dam, the largest and newest dam in the Elan Valley complex. The road leading to the dam crosses the Nantgwyllt stream, hinting at a submerged house beneath the waters.
The Sunken Road is primarily an off-road track known for its challenging conditions. It is often eroded, rocky, and frequently wet, with large puddles that require careful navigation. For walkers, this means potentially getting your feet wet or finding ways around obstacles. For mountain bikers, it offers a good off-road riding experience due to its varied and sometimes waterlogged terrain.
Yes, due to the track's often wet and rocky nature, it is highly recommended to wear waterproof footwear. Many visitors suggest wearing specialized waterproof socks, such as SealSkinz, to ensure your feet stay dry and comfortable, whether you're walking or cycling.
The Claerwen Dam is the largest and newest dam in the Elan Valley, standing 56 meters high and 355 meters long. While its exterior features dressed stone to aesthetically blend with the older Victorian-era dams, its interior is a concrete structure. It holds almost as much water as all the other Elan Valley reservoirs combined, significantly increasing Birmingham's water supply capacity.
Construction of the Claerwen Dam began in 1946 and was completed in 1952, employing 470 men. It was built to meet the increasing water demands of Birmingham and the West Midlands after World War II. Notably, Italian stonemasons were involved in the intricate dressed stone work, as many British stonemasons were occupied with post-war rebuilding efforts. Queen Elizabeth II officially opened the dam on October 23, 1952.
Yes, the Claerwen Dam features a viaduct supported by thirteen elliptical arches. The central arch houses a viewing platform, offering excellent panoramic views of the reservoir and surrounding landscape. During winter, when the reservoir is full, excess water cascades over the dam's stepped face, creating a series of impressive waterfalls.
The Sunken Road itself, being a rocky and often wet off-road track, might be challenging for very young children or those looking for an easy, paved walk. However, the wider Claerwen Valley and Elan Valley Estate offer various walking routes, some of which are more family-friendly. It's best to check specific route details for suitability.
The Elan Valley generally welcomes dogs, but they should be kept under control, especially due to the presence of livestock and wildlife. On The Sunken Road and other trails, it's advisable to keep dogs on a lead to ensure their safety and respect the natural environment and other visitors.
While specific parking for The Sunken Road viewpoint isn't detailed, visitors typically park at designated car parks near the Claerwen Dam or other points within the Elan Valley Estate and then access the trails. It's advisable to arrive early, especially during peak seasons, as parking can fill up quickly.
The Claerwen Valley is quite remote. While there might not be immediate cafes or pubs right at the dam, the wider Elan Valley Estate, particularly closer to Rhayader, offers options for refreshments. It's a good idea to bring your own snacks and drinks, especially if planning a longer hike or cycle.
The Claerwen Valley is part of the Claerwen National Nature Reserve, known for its diverse plant and animal life thriving in the peaty and acidic soil.
