Hike the Llwyn-on Reservoir loop for expansive views of deep blue waters, framed by the rolling hills of the Brecon Beacons. This easy 3.4-mile (5.5 km) route takes about 1 hour and 26 minutes to complete, with a gentle elevation gain of 129 feet (39 metres). You will pass through tranquil conifer plantations and mixed woodlands, enjoying the fresh smells of the forest and the lapping sounds of the water. Look for quaint footbridges and splendid views as you approach and walk over the dam. The trail features a mix of hard, compacted surfaces, as well as some looser, unpaved sections.

Parking is available near the trailhead, making it easy to start your adventure. For additional amenities, the nearby Garwnant Visitor Centre offers more parking, refreshments, and a cafe, serving as a good alternative starting point. You might also find a cafe or a roadside service van with refreshments along the route itself. This accessible trail is suitable for all skill levels, ensuring a pleasant experience for everyone.

The Llwyn-on Reservoir is the largest of three reservoirs in the Taff Fawr Valleys, built in 1926 following cholera outbreaks in Cardiff. Its clean waters provide a habitat for various birds, including great crested grebes, goldeneye ducks, and coots; keep an eye out for otters too, and use the available bird hides for observation. A section of the Taff Trail runs along the western side of the reservoir, offering connections to other routes, and you can also discover environmental sculptures on the Wern and Willow walks. Despite its local popularity, the area remains an under-visited gem, offering a peaceful hiking experience.

The lake attracts numerous water-loving birds, which can be observed from the bird-watching stand. It is also worth looking out for the environmental sculptures that can be found on the „Wern“ and „Willow“ trails.

A lovely hard packed trail, tucked away from the often busy Taff and Trevethic trails, the path follows the Taff for a good few km's, before coming to an end. great views of the autumn colours on the hills above too.

While on the Taff Trail the viaduct suddenly looms out of the trees, another fantastic example of the amazing construction skills of our industrial past, take a moment to stop and have a proper look.
