Cors Dyfi
PLEASE NOTE, CORS DYFI RESERVE IS CLOSED AT THE MOMENT WHILE WE BUILD THE NEW OBSERVATORY. WE HOPE TO OPEN AGAIN SOMETIME IN MAY.
THE DYFI OSPREY PROJECT WILL BE OPEN AS USUAL FROM MARCH 25TH ONWARDS. SORRY FOR THE INCONVENIENCE.
Cors Dyfi (Dyfi bog) is a wonderful little nature reserve that is teaming with wildlife for most of the year. This is where the Dyfi Osprey Project is situated.
Once estuary, reclaimed grazing, then conifer plantation and finally wildlife-rich wetland, the land at Cors Dyfi has seen many changes over the last few hundred years. Today 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're lucky, you may also spot an otter or dormouse!
When to visit
The Ospreys are typically around from April to September. Spring and Summer are also the best times to see many of Cors Dyfi’s other plants and animals, such as Common Lizard, Nightjar, Grasshopper, Reed & Sedge Warblers, Yellow Flag and Four-spotted Chaser. The Trust’s Water Buffalo graze the reserve during the Summer.

Visiting Cors Dyfi
The reserve is open year round, 24 hours a day; the osprey project is open from April to September, 10am to 6pm. During osprey project opening hours, there is a suggested donation scheme (£2.50 individual, £5 families and £10 season ticket) to help cover the costs of running the project; entry is free at other times.
With the exception of the elevated bird hide, the site is fully accessible to wheelchair users. Facilities include visitor centre with a small shop & basic refreshments; there is a disabled toilet.
Well-behaved dog owners are welcome - remember, you dog doesn't know that it is a nature reserve, so please help us retain this privilege by keeping him on a lead and clearing up any mess.
