The reserve is a man-made freshwater lake formed when an embankment was constructed to drain the flat marshland in the surrounding area.
Blanket Nook used to mark the western side of the divide of the island of Eoghain or Inishowen from Donegal. These days, this curiously titled wetland is a well-known site for waders and wildfowl. The Kingfisher is sometimes seen at the lock gates on the reserve.
You can walk from one end of the embankment to the other, though there is very little car parking space currently available. A spur of the North West Greenway between Inch Wildlife Reserve and NewtonCuningham will pass over the Blanket Nook embankment and will result in the reserve becoming far more accessible to the general public.
If you are a little hungry after visiting the reserve why not pop into Kernans Restaurant in Newtoncuningham.
