Beautiful set of “off the track” cascading falls of the Afon Caerfanell that on this side is some falls that you would normally see whilst on the usual trail that’s mapped. The terrain is very difficult and you will come across slippery mossy underfoot with the odd ditch so be careful and keep your eyes open for any recently fallen trees that may stop you from getting any further unless your like me and love a good assault course then by all means go for it, I’ll assure you that you will not be disappointed! Good footwear is essential.

The Stunning Blaen-y-Glyn Uchaf- located in Talybont has many different routes, with plenty to discover views are breathtaking. Another beaut and tip to visit is.. The Blaen-y-Glyn Uchaf waterfall circular and the Wellington Bomber Memorial Trail is fantastic walking route in Wales that will take you through the mountainous terrain of Brecon Beacons National Park to visit the crash site of a World War II Canadian bomber plane. While out walking you discover paths looping around Bwlch y Ddwyallt and Waun-Rydd to arrive at bomber site.

This is actually a nice segment that goes from Blaen y Glyn car park to the top of Fan Nedd. More than likely, this is the quickest route you can take to get some height in the Brecon Beacons. The route is quite steep, but you have some nice waterfalls to see to take your mind off things, and when you get to Fan Nedd, you are literally on a plateau where the walking gets much easier. This is the start of the walk to the Wellington Bomber War Memorial, too.

As our lovely Zoe has outlined, The Blaen-y-Glyn Uchaf and Wellington Bomber Memorial Trail is a great walk to do, and it is also not that difficult. The war memorial itself is one of the most scenic viewpoints in the Brecon Beacons.

Bwlch y Ddwyallt is the name commonly applied to the high point of the plateau of Gwaun Cerrig Llwydion in the eastern part of the Brecon Beacons in south Wales. It is a top of the mountainside of Waun Rydd. Walkers should take note that this route is a bit seasonal, as the river is tricky to cross when water levels are high in the spring/autumn.

Rassau is ideally located near several impressive waterfalls, particularly within the Brecon Beacons National Park. Key examples include the Blaen-y-Glyn Waterfalls, a series of cascades where the Nant Bwrefwr and Afon Caerfanell rivers meet. Further afield in 'Waterfall Country', you'll find the famous Four Falls Trail, home to waterfalls like Sgwd yr Eira, and the dramatic Henrhyd Falls, the highest in South Wales.
Yes, many waterfall trails in the area offer challenging terrain. The Blaen-y-Glyn Waterfalls area, for instance, features steep gradients. The Path to Craig y Fan Ddu, which includes waterfalls, is also quite steep. The Four Falls Trail in Waterfall Country is a challenging walk that typically takes at least three hours, with uneven terrain and significant ascents and descents. For those seeking a more rugged experience, the Afon Caerfanell Cascades offer very difficult, off-track terrain with slippery, mossy underfoot conditions.
While many trails can be challenging, some options are more accessible. Parc Cwm Darran Waterfall is generally easier to access, though it can dry up in summer. For easier hikes in the broader area, you can explore routes like the 'View of the Brecon Beacons – Craig y Cilau: Crags and Caves loop' or the 'Coed Fedw-ddu loop from Brynmawr', which are listed as easy hikes in the region. You can find more details on these routes in the Easy hikes around Rassau guide.
Waterfalls are often at their most impressive outside the peak summer season. Spring offers lush greenery and active wildlife, while autumn showcases vibrant golden and red forests. Winter provides a dramatic view with powerful rivers and potential icicles, though conditions can be more challenging. During summer, some smaller cascades like Parc Cwm Darran Waterfall can dry up completely.
Yes, one of the most unique experiences in the wider region is at Sgwd yr Eira (Fall of Snow) in Waterfall Country. This impressive waterfall allows visitors to walk directly behind the curtain of water. However, the path can be extremely slippery, so caution and appropriate footwear are essential.
The terrain around the waterfalls can vary significantly. Expect uneven ground, steep gradients, and potentially muddy or slippery sections, especially after rain or near the water's edge. Areas like Blaen-y-Glyn Waterfalls and the Afon Caerfanell Cascades are known for their challenging and strenuous paths. Good, sturdy footwear with excellent grip is highly recommended.
Parking is available at various starting points for waterfall trails. For instance, the Path to Craig y Fan Ddu starts from Blaen y Glyn car park. For the Four Falls Trail, Gwaun Hepste car park is a common starting point. It's advisable to check specific locations for parking availability and any potential fees before your visit.
The region around Rassau offers a wide range of outdoor activities. Besides hiking to waterfalls, you can explore numerous trails for gravel biking and mountain biking. For example, there are challenging gravel biking routes like the 'Talybont Reservoir loop' and various MTB trails such as the 'Clydach Cycle Path loop'. You can find detailed information on these activities in the Gravel biking around Rassau and MTB Trails around Rassau guides.
Many trails in the Brecon Beacons National Park, including those leading to waterfalls, are dog-friendly. However, always keep dogs under control, especially near livestock or on steep, slippery paths. For instance, near Devil's Bridge and Waterfall, caution is advised with dogs due to the fast-flowing river and steep sides. Always check local signage for specific restrictions.
Given the often challenging and wet terrain, decent, waterproof hiking shoes with good grip are essential. Layers of clothing are recommended to adapt to changing weather conditions, and waterproof outerwear is advisable, especially if you plan to walk behind a waterfall or visit during wetter seasons. Bringing a map, compass, or GPS device is also wise, as fog can roll in quickly in higher areas.
Yes, some waterfall areas are close to historical points of interest. For example, the Blaen-y-Glyn Waterfalls are part of a wider area that includes the Wellington Bomber War Memorial site, offering a blend of natural beauty and historical significance for those interested in World War II history.
Amenities can be limited directly on the trails. For instance, the Four Falls Trail has no en-route toilets, so visitors should use facilities before starting. It's best to plan ahead and carry sufficient water and snacks. Larger villages and towns surrounding the Brecon Beacons will offer cafes, pubs, and other facilities.
