On the northside of Dublin, Bull Island is a lovely place to go for a good Sunday walk along the beach or even get a game of golf.
There is a great view of Howth to your left and Dublin City and South Dublin to your right.
It is also where my friend Sinead was proposed to by the love of her life :)
There is an interpretative centre on the island as well as a bird sanctuary. You can take the boat out here as well as you can see here.
You can get the Dart to Clontarf and keep walking along on the coast road til you see the Bull bridge over to the island. Or get the 130 bus from the city centre and ask the driver to tell you where to get out for the island.
If you are driving, be very slow, as the bridge between the mainland and the island is very narrow.
Also, bear in mind that many people have their first driving lessons on the beach, so watch out! :)
The Dublin harbour was always known for sitling up badly and having rough waters. So Captain Bligh (of Mutiny on the Bounty fame) built this wall in the bay to break the waters. This solved the problem promptly and soon enough a whole island formed behind the wall as the bay silted up against the wall as opposed to inside the harbour.
The mud in the tide pool between the island and the mainland became very rich in nutrients and is now one of the best Bird pubs in Dublin. If you have any interest in birdwatching you might want to pay a visit to the North Bull Island for loads of waterbirds and waders.
By the way, I'm still not sure what a "bull" is, if not a male bovine animal, but Dublin bay also has a much lesser known South Bull (Sandymount strand). I'll post a tip on Sandymount strand too as it is worth a visit but there is no island like on the North Bull.
Bull Island is an Island near Dublin Port. Just a tad to the North. On my map it's called North Bull Island, but I couldn't find any South Bull Island, so I guess looking for Bull Island will get you there eventually.
It's basically just an island. There's nothing on there except of course the inevitable golf course. You can't have a piece of empty land larger than 10 sqm without a golf course on it in Dublin. Goes without saying...
The island is beautiful though. You'd go there to look at nature, birds, plants, the views etcetera. Or just to walk on the beach, fresh summer breeze (storm) through your hair. The more active people among us could go there to practice their Kite surfing abilities. I really ought to try that once, if I ever get the nerve...
Go there if you have the time. I found it one of the more relaxing areas of Dublin. Great for a lost Sunday afternoon or a romantic (if you can stand a little sand in your eyes) stroll on the beach.
