Hi Juliette,
Right off the top of my head, I started think of some of the awesome
day trips from Dublin! There are several that came to mind, and are easily visit-able through public transport.
With your interest in castles, you may want to check out Trim Castle (from Mel Gibson’s Braveheart) or spend your time exploring Powerscourt House & Gardens.
For sure you could have a lovely evening in either County Meath or County Wicklow. With B&Bs and more available, feel free to make use of our
accommodation search tool to help you find the perfect spot for an overnight.
Give us a shout if we can help you with anything else.
I'm curious as to what our members here would suggest. We'd love to hear from you!
