There is something special about escaping the city and spending time in the Welsh countryside. A Craig-y-Nos Walk is one of the best ways to experience the beauty, history and tranquillity of the Upper Swansea Valley. On one of the hottest days of the summer, a group of friends travelled from Swansea to Craig-y-Nos Country Park to enjoy a gentle circular walk through woodland, lakeside scenery and historic parkland.
As someone who grew up nearby, it was wonderful to share this beautiful corner of South Wales with friends who had never visited before. Although the soaring temperatures encouraged us to keep our walk fairly short, the stunning surroundings and fascinating history made it a memorable day out.
A Relaxed Lunch Before Our Walk
Before heading to the country park, we stopped in nearby Ystradgynlais for lunch at Loaf Kitchen & Bar. It proved to be the perfect way to begin the day before exploring the park.

Discovering Craig-y-Nos Country Park
Nestled on the edge of the Bannau Brycheiniog National Park, Craig-y-Nos Country Park occupies the former Victorian pleasure gardens of Craig-y-Nos Castle. The 40-acre park was once the private estate of world-renowned opera singer Adelina Patti, whose influence can still be seen throughout the landscape today. The park is now managed by the Bannau Brycheiniog National Park Authority and offers gentle walking routes, lakes, woodland, riverside paths and picnic areas for visitors to enjoy.
Walking through the grounds feels like stepping back in time. Every corner reveals another glimpse of Victorian landscaping carefully blended with the natural beauty of the Upper Swansea Valley.
Following the Short Circular Walk
We chose the easy circular route, which is ideal for families, casual walkers and anyone looking for a leisurely stroll. The path winds through mature woodland, alongside tranquil lakes and across open lawns, with plenty of benches where you can pause and admire the surroundings.
Although the official circular walk is only around 2.2 kilometres, it offers plenty to see along the way and can easily fill an afternoon if you take your time. The accessible paths and gentle gradients make it suitable for most visitors.
With temperatures climbing throughout the afternoon, we decided not to rush. Instead, we enjoyed the slower pace that the park naturally encourages.
The Rivers That Shape the Park
One of the most distinctive features of Craig-y-Nos Country Park is its waterways. Two rivers flow through the historic grounds, helping to shape the landscape and create the peaceful atmosphere visitors enjoy today.
The smaller of the two is the River Llynfell, which emerges from the extensive underground cave system beneath the nearby Dan-yr-Ogof National Showcaves Centre for Wales. After travelling through the limestone caves of the Black Mountain, the water resurfaces and continues its journey through the park. The clear waters of the Llynfell support a variety of wildlife and contribute to the rich biodiversity found throughout the area.
The larger River Tawe also passes through the country park. Rising high on the slopes of the Black Mountain within Bannau Brycheiniog National Park, the River Tawe begins its journey in the uplands before flowing through the Upper Swansea Valley. As it meanders through Craig-y-Nos Country Park, the river adds movement, colour and tranquillity to the landscape. Eventually, it continues south through communities including Ystradgynlais, Pontardawe and Swansea before reaching Swansea Bay.
Together, these two rivers play an important role in shaping the park’s natural environment. Their waters nourish the surrounding woodland, support local wildlife and enhance the beauty of a landscape that has attracted visitors for generations.
A Landscape Shaped by History
One of the things my friends found most fascinating was learning about the remarkable history of the estate.
During Adelina Patti’s ownership, Craig-y-Nos featured everything expected of an impressive Victorian country estate. There were ornamental gardens, glasshouses, a croquet lawn, rose gardens, fishing ponds and a remarkable collection of native and exotic trees, including walnut, mulberry, eucalyptus and acacia. Later, the castle became a tuberculosis sanatorium, giving the estate another important chapter in Welsh history.
Knowing this history adds another dimension to the walk. Every bridge, pathway and lakeside view feels connected to the many people who have lived, worked and recovered here over the decades.
Nature’s Beauty and Nature’s Challenges
While the park remains incredibly beautiful, there was one sight that saddened us all.
Many of the mature trees had suffered extensive storm damage. Along several paths we saw large trunks that had been cut into sections after being blown down by severe weather. Seeing these magnificent old trees lost was disappointing, especially knowing that many had stood for generations.
Hopefully, where possible, replacement trees can be planted over time. Although they will never replace the original century-old specimens overnight, future generations deserve the opportunity to enjoy the same mature landscape that has made Craig-y-Nos so special.
Even with this damage, the woodland still provides an impressive display of colour, texture and wildlife.
Time to Sit and Enjoy the Lakes
The heat eventually persuaded us to slow down even more.
Rather than completing every path, we found ourselves drawn to the benches overlooking the peaceful lakes. Watching the water shimmer beneath the summer sunshine while listening to birdsong created one of those simple moments that reminds you why places like this are so important.
Sometimes the best part of a walk is simply stopping to appreciate your surroundings.
A Well-Earned Ice Cream
No summer walk is complete without a refreshing treat.
After returning to the car park, we visited the café overlooking the lake and enjoyed delicious artisan ice cream from Llanfaes Dairy. Sitting outside with beautiful views across the water was the perfect way to finish our afternoon together.

Final Thoughts
Craig-y-Nos Country Park remains one of the hidden gems of the Upper Swansea Valley. Whether you’re interested in history, photography, wildlife or simply enjoying a peaceful walk, the park offers something for everyone.
Even on an exceptionally hot day, when our walk was shorter than planned, spending time with friends in such beautiful surroundings made the visit worthwhile. The combination of Victorian heritage, mature woodland, peaceful lakes and accessible walking trails creates a destination that is easy to recommend.
If you are visiting the Bannau Brycheiniog National Park or exploring the Swansea Valley, Craig-y-Nos Country Park deserves a place on your itinerary. Take your time, enjoy the scenery, and don’t forget to finish your visit with an ice cream overlooking the lake.
