About the reserve

Cors Dyfi is a wonderful nature reserve that is teeming 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 Project website is packed with information on the ospreys and the nature reserve they call home: click here.

The ospreys are typically around from April to September. Spring and summer are also the best times to see common lizards, grasshopper, reed & sedge warblers, yellow flag iris and four-spotted chaser dragonflies. 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 there are regularly otter and red kites on the reserve.

In April 2021, we introduced a family of beavers into an enclosure on the reserve; for more information, click here.

Cors Dyfi facilities include the fabulous Dyfi Wildlife Centre, Dyfi 360 Observatory, a bird hide and accessible Changing Places toilets. We have educational facilities on site and welcome group bookings. Dogs are welcome in the car park and the seating area to the front of the visitor centre, but with the exception of Assistance Dogs, are not permitted in the building or on the reserve. Water bowls are provided. There are 15 electric vehicle fast chargers in the car park.
