Pwll y wrach

Pwll y wrach is a waterfall on the River Ennig beside the town of Talgarth in southern Powys, Wales. It sits below the Black Mountains escarpment, on the edge of Bannau Brycheiniog (Brecon Beacons) National Park. The Welsh name means "the witch's pool", and visitors also know it as the Witches' Pool.

What will you see?

The river drops in two separate streams over a ledge of hard rock into a deep, shadowy plunge pool. Over thousands of years the falling water has cut that basin out of the softer Raglan Mudstone beneath. The fall sits in a wooded gorge, so it only comes into view when you are close, and moss covers most of the stones in the damp air.

The surrounding woodland is a nature reserve of oak and ash, protected as a Site of Special Scientific Interest and run by a Wildlife Trust. Entry is free.

Why is it called the Witches' Pool?

Local tradition says people accused of witchcraft were ducked in the pool below the fall. That is folklore rather than documented history, but it gave the place its name.

How do you get there?

Talgarth is the easiest starting point. Leave the car in the free car park in town, because the reserve itself has only a few rough parking spots. A surfaced, easy path runs from the main car park into the reserve. The final stretch to the waterfall is uneven, muddy after rain and slippery in winter.

Published routes vary. A short walk from Talgarth covers roughly 4.5 km in a little over an hour. A longer loop runs about 9.6 km and takes around three hours, and you can cut it short after the falls and head back to town. Expect stiles, and keep dogs on leads where sheep graze.

When should you visit?

The woods are rewarding all year, but spring is the highlight, when bluebells blanket the ground. After heavy rain the fall carries the most water. Wear shoes with good grip. Dippers and grey wagtails are regular sights along the river.

What else is nearby?

Talgarth Mill, a restored 18th-century watermill, stands in the town. Nearby Bronllys has the remains of a 12th-century castle. Both fit easily into a day out with the waterfall walk.

Frequently asked questions

Is there an entrance fee for Pwll y wrach? No. The reserve is free to enter.

Can you park at the reserve? Parking on site is very limited and rough. The free car park in Talgarth is the better choice, followed by a walk.

Is the route suitable for children or pushchairs? The surfaced path from the car park into the reserve is easy, but the track up to the waterfall is uneven and muddy, so pushchairs will not manage it.

Can you swim in the pool? The pool is for looking at, not swimming. The rocks are slippery and the water is deep, so enjoy it from the bank.
