If you’re open to a private tour, I’d really recommend Little Gem Tours. I went with them and it honestly ended up being one of the best trips I’ve ever done. They do small, personalised tours all around Ireland (North included) and you can stay in B&Bs, little villages, even castles if you want.What I loved is that it didn’t feel like a big organised tour at all, more like travelling with a local who knows the history, the farms, the hidden places and the good walking spots. You can include cultural stops, rural life, light hiking, whatever you’re into.Worth checking out if you decide to go the private/small group route!
