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.
The best way to experience the reserve is to follow the boardwalk into the heart of the fen.
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 walking trail is waymarked from start to finish.
Look out for the information panel at the start of the trail.
Find out about walking trail grades.
You can follow the Tennant Canal towpath along the length of Pant y Sais Fen, and beyond the reserve in either direction as far as Swansea or Neath.
The Wales Coast Path passes the edge of the reserve.
You can join it underneath the bridge over the canal.
Find out more about the Wales Coast Path.
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.
