Dublin, Ireland
If Irish culture is on your list to explore, Dublin is the place you should be in. It has plenty of options ranging from diners to boarders, exquisite tea shops and parks for a solo woman traveller. But then again, as a solo traveller be thorough with your research so that you are totally prepared for the trip.
Deemed as the best literary city by UNESCO, you can follow in the footsteps of George Bernard Shaw, Oscar Wilde and James Joyce on one of the famous walking tours that trail throughout the city, especially by the banks of Portobello canal.
