Dag Marc,
It's wonderful that you are coming to Ireland with your family!
For accommodation in Wicklow National Park, there aren't any places to stay within the park itself, but I would suggest going to nearby towns like Glendalough, Laragh, and Roundwood. You can find accommodation through our
search tool or by using
B&B Ireland and
Let's Go Self Catering. You can also wild camp in some areas of
the national park if you and your family are up for it. :)
For footwear, I recommend light hiking shoes with good grip, great to discover cities and the Wicklow mountains at the same time. Are there walking trails that you are interested in? The
National Parks website lists all of them, just in case.
For traveling without a car, you can take a bus from Dublin to Glendalough with
St Kevin's Bus and from Dublin to Cork with Bus Eireann or Irish Rail. Feel free to use the
Journey Planner of Transport for Ireland for info on routes, tickets and schedules.
Please us know how your plans are coming along or if you need to discuss what I just shared. 😊
Groet,
Antoine
