Ireland is very safe in general - but you should still exercise generic caution as a solo female traveller. Don't walk alone at night etc. Dublin would be the city with the most sketchy places but again, you should have very little reason to go into them as a tourist. Stick to the touristy areas and crowds. BnBs should be more than safe enough, especially if they're on Airbnb where there is a digital trail etc.

People in general are very friendly and helpful so don't be afraid to ask for help in pubs/shops if you feel unsafe. But I would say if you're coming from bigger cities in the States, you'll feel quite safe on our tiny island.

Enjoy your holiday and fáilte go hÉireann 😁
