Things for English language students to do when visiting Dublin

When students come to attend an English language course at the DLTC Language School, we advise on places to visit in the local and wider area. Here are some of the better things to do:

Phoenix Park: to the west of Dublin. You can take the red tram (LUAS) line to get there and one of the nicest ways of seeing the park is by bike - you can hire bicycles in the park for 1, 2, 3 hours at a time: http://www.phoenixpark.ie/)
The Guinness Factory in Dublin 8. It costs 14 euros (for which you get a 'free' pint of Guinness in the rooftop bar). Take the red LUAS line or one of the many buses from the city centre - walking takes at least 30 minutes from Trinity College in the centre of Dublin: http://www.guinness-storehouse.com/en/Index.aspx)
Kilmainham jail: Dublin 8. The historic prison has been converted into a museum that remembers Ireland's struggle for independence from Britain. http://www.kilmainham-gaol.com/why.htm)
Malahide Castle: North Dublin - you can take the DART (train)to Malahide Station: http://www.malahidecastle.com/)
Powerscourt Gardens: Enniskerry, these are beautiful gardens set at the base of the Wicklow Mountains. Typically beautiful Irish landscape. 6 euros (Take the number 44 bus that goes from Townsend Street or the bus from Bray DART station (only leaves about every one hour so check your times on http://www.dublinbus.ie/ . For Powerscourt see: http://www.powerscourt.ie/gardens/)
Powerscourt Waterfall: Enniskerry, beautiful waterfall set against the Wicklow Mountains. 5/6 euros (Difficult to get to without a car but you can take the above buses to Enniskerry and then its a 7 km walk through beautiful countryside - be careful on the small roads!)http://www.powerscourt.ie/gardens/waterfall/)
Howth: North Dublin, a fine place to eat and buy seafood. There is a beautiful walk around the headland and every few weeks a DLTC Language School teacher will bring English language students around this walk for free. Take the train (DART) to Howth
Newgrange: near Drogheda, these are tombs that are older than the pyramids of Egypt some of which you can enter (there are tours from the bus station in Dublin http://www.knowth.com/newgrange.htm)
Cliff of Moher: Incredible cliffs on the west coast of Ireland that fall into the Atlantic ocean (take a bus to Galway and after a bus to the cliffs - this will take at least a full day and we would advise two days - or you can take a one or two day bus tour: http://www.cliffsofmoher.ie/)
