Henrhyd Falls is the tallest waterfall in southern Wales with a drop of around 90 feet 927 m). It's managed by the National Trust and visible via a short walk down into the gorge below. It's not bike suitable but is worth leaving the bikes for a look. The mobile cafe at the car park serves snacks, ice cream, burgers, and drinks. They also run a campsite.

Good walking shoes and a hiking stick, easy to tumble if your old. https://youtu.be/Atw5aOeGxcU?si=TAtRZze21RnrDzyE

Definitely take a breathable waterproof jacket and water. Excellent weather all around the UK the day I hiked, but the weather can change quick the higher you climb.

The gorges around Hirwaun are located at the southern edge of the Brecon Beacons National Park, a region known as "Waterfall Country." You'll find numerous steep-sided valleys and gorges carved by rivers, often featuring spectacular waterfalls. The geology showcases significant processes where deep valleys have been formed by the relentless action of water over time, primarily through old red sandstone and limestone grit.
Yes, the area is renowned for its waterfalls. Highlights include Henrhyd Falls, the highest waterfall in South Wales, plunging 90 feet into a wooded gorge. Another popular spot is Sgwd Uchaf Clun-Gwyn Waterfall, which comprises two sets of falls, with the upper falls thundering dramatically into the River Mellte. The Gorges of the Four Waterfalls Walk also features several impressive cascades like Sgwd yr Eira, where you can walk behind the water.
The gorges offer a variety of walking and hiking experiences. For instance, the trail to Henrhyd Falls takes about 10 minutes from the car park, with a longer valley trail lasting about an hour. The famous Four Waterfalls Walk near Ystradfellte is a major highlight, involving trails that lead to multiple waterfalls within stunning gorges. Many trails involve descending into valleys, such as the 170 steps to Sgwd yr Eira.
While traditional canyoning might be limited, the natural topography of these gorges lends itself well to activities like gorge walking or scrambling. This involves navigating river courses by scrambling over rocks, swimming through pools, and sometimes jumping into water, offering a comparable thrill of exploring water-filled, narrow valleys. For more information on this type of activity, you can visit Visit Wales.
Many of the trails and waterfalls are suitable for families, though some sections can be challenging. For example, Henrhyd Falls is considered family-friendly, but caution is advised due to slippery rocks near the waterfall. Trails like the Four Waterfalls Walk are popular with families, but some descents, such as the 170 steps to Sgwd yr Eira, require a reasonable level of fitness. Always check specific trail conditions for younger children.
The gorges and waterfalls can be visited year-round, but each season offers a different experience. Spring and autumn provide lush scenery and comfortable temperatures for walking. During winter, the waterfalls can be particularly dramatic with higher water flows, but trails may be slippery and require appropriate gear. Summer is popular for outdoor activities, but water levels might be lower. Always check local weather conditions before your visit.
Yes, some areas within the gorges offer opportunities for wild swimming. For example, Pwll Berw Falls is noted for its amazing wild swimming pools. However, trails down to these pools can be loose and steep, so good footwear is essential. Always exercise caution, check water conditions, and be aware of potential hazards when wild swimming.
Visitors frequently praise the immersive natural beauty, the spectacular waterfalls (especially those you can walk behind like Sgwd yr Eira and Henrhyd Falls), and the tranquil ancient woodlands. The diverse ecosystems, rich with mosses, liverworts, and lichen, along with various bird species, also contribute to the appeal. Many find the walks incredibly rewarding, describing them as 'worth every step'.
Beyond exploring the gorges, the Hirwaun area offers a range of outdoor activities. You can find numerous gravel biking routes, such as those detailed in the Gravel biking around Hirwaun guide. There are also extensive running trails, including the Ystradfellte Waterfall loop, which you can explore in the Running Trails around Hirwaun guide, and road cycling routes like those found in the Road Cycling Routes around Hirwaun guide.
While popular spots like the Four Waterfalls Walk can get busy, exploring areas slightly off the main routes or visiting during off-peak times can offer a more tranquil experience. Consider exploring less-trafficked sections of the Brecon Beacons or seeking out smaller, local gorges. For example, the Blaen Taf Fawr Valley offers a small gorge with a waterfall and can be part of a challenging hike with fantastic views.
Access points for the gorges and waterfalls often have dedicated car parks. For the Four Waterfalls Walk, popular starting points with parking include Ystradfellte, Porth Yr Ogof, or Pontneddfechan. For Henrhyd Falls, there's a car park from which the waterfall is about a 10-minute walk. Always check for specific parking information and any potential fees or restrictions before your visit.
