Sitting in the broad expanse of Dublin Bay, Bull Island (also known as North Bull Island) has a lot going for it. For starters, it’s a biosphere reserve and a Special Area of Conservation. But the titles don’t stop there. This sandy island, which is connected to the mainland by a wooden road bridge, is also a National Nature Reserve and a National Bird Sanctuary, so, needless to say, it’s a pretty good spot to go birdwatching.

Go exploring around the mudflats and dunes here and you’ll feel like you’re a million miles away from city life, as you spot species such as the Brent goose, northern pintail, the European golden plover, short-eared owl and the magnificent peregrine falcon. The island is car-free so the best way to enjoy it is by bike from Dublin city centre – a journey of about 10km.

With its wilderness of hauntingly beautiful mountains, shimmering lakes and Baronial-style castle, Glenveagh is effortlessly romantic and endlessly mesmerising. Remote, rugged and boasting a variety of habitats from woodland to peatland, the park attracts a wide range of bird species from migrants to residents.

The golden eagle was reintroduced to Ireland in 2001 and the first birds were released right here in Glenveagh. While the park cannot claim any eagles to be resident at present, they frequently forage in the valley here.

Keep your eye out, too for the peregrine falcon, merlin, sparrowhawk and kestrel, and, if you’re visiting in May, you might be lucky enough to hear the distinctive singing of the male wood warbler – a sound that’s been likened to the spinning of a coin. There are lots of walking trails available, from the 3.5km lakeside walk to the 7km Lough Insagh Walk, making it a great place to relax, restore and enjoy the flora and fauna of this magnificent place.

The largest lough in the UK and Ireland, Strangford has beauty in abundance. Connected by a narrow channel to the Irish Sea, the lough is almost fully enclosed by the Ards Peninsula and is a wonderful mix of unique towns, ancient history and wonderful wildlife.

The mild conditions in winter make it the preferred destination for more than 70,000 seabirds who migrate here from northerly latitudes, including a high proportion of Brent geese from Arctic Canada. Spring is another great time to spot breeding birds, including nesting herons, tree sparrows and yellowhammers. And if you like your marine life as much as your bird life, you’re in luck – both common and grey seals can be spotted in the lough all year round.
