Belfast is safe for anyone to visit, whether you are traveling solo or in a group. As mentioned before, the Belfast people are very talkative and friendly, so if you want to make friends at a bar or pub, it would be very easy to get to talk to people.
For an authentic Belfast experience give yourself three days to soak up the history, culture and sights. Belfast has a compact heart, and many of its best sites are within walking distance of one another.
It also possesses vitality and spirit and is infused with more than just a wee bit of Irish charm. In fact, I discovered there are so many things to do in Belfast it's almost overwhelming if you only have a few days in the city. But even if you have only one day to spend visiting Belfast, it's well worth visiting.
