About the reserve

CORS DYFI IS CURRENTLY CLOSED. Our new Dyfi Wildlife Centre was due to open in April 2020, but due to Covid-19, we were not able to. We look forward to welcoming you to the new centre in 2021, in line with Welsh Government easing of lockdown. For more information, click here.

Cors Dyfi is a wonderful little nature reserve that is teaming with wildlife. Over the last few hundred years it has seen many changes, from estuarine salt marsh to reclaimed grazing, then to conifer plantation and more recently into a wildlife rich wetland reserve. The reserve is a healthy mixture of bog, swamp, wet woodland and scrub supporting a plethora of animals and plants. Including the magnificent Osprey, which bred on the reserve for the first time in 2011. If you are lucky you may also spot an otter or dormouse.

Our Dyfi Osprey website is packed with information on the ospreys and the nature reserve they call home: click here.

The Ospreys are typically here from April to September. Spring and Summer are also the best times to see Common Lizards, Nightjars, Grasshopper, Reed & Sedge Warblers, Yellow Flag Iris and Four-spotted Chasers. The Trust’s Water Buffalo graze the reserve during the Summer. The winter brings a host of small birds to the feeders as well as Barnacle Geese and Hen Harriers to the wider reserve. During the winter you may even glimpse the elusive Bittern in the reed beds. Year round we regularly see Otters and Red Kites on the reserve.

Cors Dyfi Facilities include Dyfi 360 Observatory, two bird hides, visitor centre with a small shop & basic refreshments and accessible toilets. We have educational facilities on site and welcome group bookings. Dogs are welcome in the car park and visitor centre, but with the exception of Assistance Dogs, dogs are no longer allowed on the reserve. Water bowls are provided.
