Hello all, I will be traveling to Ireland solo mid-late June for 4 nights before continuing on to a longer family trip in Scotland. International flight gets into Dublin on the 21st and I am flying out of Belfast to EDI on the 25th so I am planning on 2 nights in each Dublin and Belfast. I am in my mid-twenties, love museums/architecture/nature, and plan on enjoying traditional Irish music alongside some traditional Irish drinks.
First question is whether the day trips from Belfast to Giant's Causeway and other coastal sights are worth it. They all seem touristy, but may give a taste of the countryside for future trips. Secondly, I am planning on taking the commuter train from Dublin -> Belfast, are there any stops directly on the route that are easy and worth making? I am open to any and all other recommendations for the two cities. Thank you all!
