Pant y Sais National Nature Reserve shares many similarities with the nearby – but much larger – Crymlyn Bog to the west.
The reed and sedge beds are home to a range of wetland plants, birds and insects.
Running alongside Pant y Sais is the Tennant Canal. Along with a variety of birds and dragonflies, the banks of the canal are also home to the fen raft spider – Britain’s largest spider.
The best way to experience the reserve is to follow the boardwalk into the heart of the fen.
Pant y Sais is a National Nature Reserve.
National Nature Reserves are places with some of the very finest examples of wildlife habitats and geological features.
There are over 70 National Nature Reserves in Wales.
The best time of year to visit Pant y Sais is during the summer, when the reserve is alive with the sound of bird song.
Reed warblers and sedge warblers breed here, along with Cetti’s warbler, grasshopper warbler, reed bunting and water rail.
Scarcer visitors, normally associated with the East Anglian fens, include bittern, marsh harrier and bearded tit.
Summer is also a good time to see the various wetland plants. Amongst the reed and sedges, special wetland flowers include yellow iris, marsh cinquefoil and greater spearwort.
Look out for the big clumps of royal fern – a Pant y Sais speciality.
Britain’s largest and rarest spider, the fen raft spider, lives here but you are much more likely to spot butterflies and dragonflies during your visit.

The circular boardwalk takes you into the heart of the fen. Please stay on the boardwalk when out on the fen as there is dangerous wet ground.
From the other end of the boardwalk you can also follow the towpath which runs alongside the Tennant Canal. You can follow this along the whole length of Pant y Sais Fen, and beyond the reserve in either direction as far as Swansea or Neath.
The Wales Coast Path also passes the edge of the reserve.
The circular boardwalk is accessible to wheelchairs. The boardwalk leads from the B4290 – please take care crossing the road.
The other access to the reserve is along the towpath adjacent to the Tennant Canal. The towpath is not accessible to wheelchairs.
Pant y Sais is located adjacent to the B4290, ½ mile from its junction with the A483.

There is limited parking on this residential road, please park considerately. Walk back to the B4290 and walk up the pavement towards the bus stop which is on the side of the road where the houses are. The entrance to the boardwalk is behind some railings. Please take care crossing the road.
