The Castell Coch and Craig Yr Allt Circular is a truly wonderful and scenic explore just outside of Cardiff, Wales.
This route perfectly combines historical intrigue with demanding outdoors activities, guiding you through the ancient woodlands of Fforest Fawr and up to the stunning panoramic views from Craig yr Allt.
I chose this trail for its dramatic ascent and the irresistible allure of the fairytale-like Castell Coch (Red Castle), a spectacular piece of Welsh heritage and tourism.
Key Takeaways
- My Core Activity: A moderately strenuous circular hike with a demanding, steep climb.
- The Route’s Distance: A substantial loop, estimated to be around 5–7 miles based on the terrain.
- Key Landmarks: Castell Coch (Mock-Medieval Castle), Craig yr Allt (Moorland Hill), Fforest Fawr, and the Taff Trail.
- The Path’s Surface: Forest paths, established long-distance trail (Taff Trail), and moorland track (can get overgrown at times).
- My Rating: Moderate to Strenuous, due to the steep climb and potential for rough, overgrown sections.
The Full Loop: My Ascent to Stunning Views
My explore on the Castell Coch and Craig Yr Allt Circular began at the car park by Castell Coch, setting a dramatic, historical tone immediately. This site is steeped in history: the original fortress dates back to the 11th century, and although the 13th-century castle was destroyed in the Welsh Rebellion in 1314, the current structure is an incredible, lavish, fairytale-like castle built in the 1870s. This mock-medieval castle, built to reproduce an old stronghold, still incorporates remains of a 13th-century castle. While mock-medieval, its dramatic appearance rivals the genuine historical sites like the Stanton Drew Stone Circles I encountered in Somerset.

The initial part of the route followed the Taff Trail through the dense woodland of Fforest Fawr and around Taffs Well. The Taff Trail is an impressive piece of infrastructure—a 55-mile (88km) long-distance walking and cycling route connecting Cardiff and Brecon, traversing the dramatic scenery of Bannau Brycheiniog.
After this relatively easy stretch, the real challenge began: the switchback ascent up the moorland hill of Craig yr Allt. This is described as quite a steep climb up onto the ridgeway, requiring a demanding piece of outdoors activities. The views, however, make it worthwhile.
Once on top, I followed the exhilarating Ridge Walk across Craig yr Allt, which provided truly stunning views over Cardiff, the Channel, and the distinctive outline of Garth Mountain. From this elevated position, I also had magnificent views overlooking Caerphilly.
The descent led me back to the lane and into the ancient beech woodland of Fforest Fawr. Navigating the smaller paths, exploring the woodland, I made my way back to the car park. It is important knowledge that some of the paths can get overgrown at times, so long trousers are advised for comfort.
I completed the full circuit (around 6 miles) in approximately 3 hours and 30 minutes, factoring in the effort of the steep climb and time for enjoying the views.

Getting There: Transport and Timing
Access to this countryside explore is focused on the car park at the trailhead. I chose a bright morning for my visit to ensure clear visibility for the stunning views from the ridge.
Driving and Parking Details
Driving is the most practical way to start this trail.
- Parking Situation: The trail starts from the car park by Castell Coch. Since the castle is a major visitor attraction, parking is usually well-established.
Public Transport Details
- Bus/Rail: While the Taff Trail connects to major transport hubs in Cardiff, reaching the specific Castell Coch car park via public transport may involve a lengthy walk or a combination of services. The flat, paved, and transport-accessible Bristol and Bath Railway Path offers a stark contrast in convenience.

| Transport Method | My Estimated Time from Leeds City Centre | My Cost | Notes |
|---|---|---|---|
| Car (Driving) | 20 minutes | Parking fees (if applicable) + Fuel | Most direct start for the circular hike. |
| Bus + Walk | 45+ minutes | Standard fare | Feasible, but requires checking local bus routes to the castle. |
I found driving to the Castell Coch car park to be the most efficient way to start the explore.
Beyond the Path: Running, Safety, and Long-Distance Access
This trail offers great terrain for advanced run training and acts as a gateway to wider outdoors activities in Wales.
Trail Running and Endurance
- My Run Assessment: The Taff Trail sections through Fforest Fawr are excellent for steady trail running. However, the steep climb up Craig yr Allt means this route is only suitable for runners looking for a challenging, hill-training session.
- Terrain Caution: Runners should be aware of the possibility of overgrown paths on the descent and wear appropriate gear, including long trousers for protection.
Taff Trail Connection
- The route provides a taste of the Taff Trail, which is an essential piece of knowledge for any serious walker or cyclist in Wales, as it connects to the vast national park of Bannau Brycheiniog.
Forest and Riverside Comparison
- The variety of paths in the ancient beech woodland of Fforest Fawr offers a richer, more challenging forest walk than the gentler, more maintained tracks of the Snuff Mills and Oldbury Court Circular.
