You can reach Howth using the DART, a fast train service, from Dublin's city center. Return ticket costs â¬4.70 from Connolly, Tara or Pearse stations in the City Centre and is valid one day. There are trains every 15 minutes. Take the train north to Howth. You will arrive near the Harbour. The train takes between 25 and 30 minutes from Connolly Station.
Notice: There is one train going to Howth, and the other going to Malahide. They both go in the same direction, but do not halt at the same stations. If it's not written "Howth", it's not going there.
Alternatively, you can take a bus from Connolly, line 31 will take you up to Howth's Harbour and line 31B up to Howth's Summit. Tickets can be bought in the bus prepare your change. There is approximately one bus every half-hour or so.
The bus needs to travel through heavy traffic and across a tram line to get to the stop opposite Connolly station and so the time can vary when it arrives, it is best to be at the Connolly bus stop at the time the bus is due to leave and be vigilant as many busses crowd the stop and some may not stop -- be assertive when hailing the bus.
The 31 and 31B both start from the same location; Eden Quay. It is just off O'Connell Street. With your back to the O'Connell Statue and facing O'Connell Bridge turn left and follow the river, you should be on the side of the road away from the river. Continue past the T-junction, where you should see the Abbey theatre. The bus stop is the second before the railway bridge.
