The Southside coastal areas stretch from Sandymount Strand all the way out to Greystones and are well linked with the DART commuter rail system, which provides beautiful scenery along with swift transport. Seaside towns like Blackrock, Dún Laoghaire and Dalkey have many scenic walks, restaurants and pubs along with historical monuments as well as being the starting point in James Joyce's famous Ulysses.
Seafood lovers with appreciate restaurants such as Caviston's in Glasthule and Ouzo's in Dalkey where the fish is freshly caught daily by local fishermen and is directly traceable. Getting a Teddy's ice cream before walking Dún Laoghaire Pier is a Dublin institution and taking a dip at Seapoint is a must when the weather is good. You can watch dingy regattas and take a trip to Dalkey Island from Bullock Harbor depending on the weather conditions.
These sleepy towns often come alive at night with plenty of pubs and bars to choose from. If you want to go clubbing then Dún Laoghaire and Bray are your first ports of call whereas Dalkey has a string of authentic Irish pubs that are full of locals.
