As this is a mainly wet site, wellington boots are recommened all year round.  The path is indistinct, uneven and prone to being slippery in places.  Boardwalks provide access across the wetter areas.


From Llandrindod Wells lake, follow the road to the golf club. Go over the cattle grid and park in the lay-by on the right just past the church.

Follow the public footpath through churchyard, exit into field. Turn right and leave field through hidden wooden gate on right. Descend steps and bear right on the track, bear left almost immediately following the public footpath signs around the farmhouse.

Turn left on track and follow this track for 400m until you see the reserve on your right. Look out for our interpretation board.

About the reserve

The lake in this reserve was created by damming up the stream back in the 1950's for fishing.  Today, the lake is very small with much of the reserve being swamp, fen and wet woodland.

In the winter, the mire is an important roost site for large numbers of snipe, jack snipe and pied wagtail.  Widgeon, teal and other water birds find the open water attractive and water rail love to hide in the tall vegatation around the edge of the water.

The summer months sees dragonflies and damselflies dancing above the water and butterflies enjoying the flowering plants and rich wetland.

Bird species include bullfinch, skylark, linnet, reed bunting and song thrush, with red kite, buzzard and raven on occassion.

Frogs and smooth newts can be found among the sedges, northern marsh-orchids, broad-leaved cotton-sedge and bog violets growing on the damp soils.

Pentrosfa Mire's rarest species is a lichen discovered on willow twigs which is new to science (a member of the Arthonia genus).  Over 100 species of lichen have been found on this reserve.
