Cardiff: Hailey Park to Blackweir Bridge on the Taff Trail

Start at Hailey Park’s public car park off Radyr Road in Llandaff North. Take the surfaced park path to the River Taff, then turn left onto the signed Taff Trail towards Cardiff. This return walk follows the river through the southern end of Hailey Park and beneath Llandaff Bridge, with views across the water towards Llandaff’s riverside meadows.

Stay on the main riverside trail as it bends past the Millennium Milepost and continues beneath Western Avenue. Use the path under the A48, rather than the steps up to the road bridge. Beyond Gabalfa Woods, follow the river’s broad bend to Blackweir Bridge. Cross the pedestrian bridge for the view of Blackweir and the edge of Pontcanna Fields, then turn back and retrace the same trail to Hailey Park and the car park.

Allow about 2 hours 15 minutes for roughly 7 km, including a brief pause at the weir. The route is mostly level and surfaced, with slopes through the underpasses. It is a shared walking and cycling route, so keep dogs close and leave room for passing cycles. Do not approach the weir or enter the river. Riversides and underpasses can flood or become slippery after heavy rain; follow any local closure signs.

Hailey Park has no public toilets. Check the car park signs on arrival and take water. Plan the walk in daylight and observe any park gate or event restrictions around Blackweir.
