Hi Sara,
As you can appreciate this is our winter so the temperatures will be lower than during our summer.
It is very rare that rain affects our transport for long, if at all, as we are used to a bit of rain! 🌦️
As long as you have a
suitable coat and put a few layers on, we are sure you will enjoy the Irish
weather.
Irish Rail runs the train services in the Republic of Ireland. Most trains run from Dublin to places such as Galway, Limerick, and Cork directly. It would be necessary to return to Dublin to get from one place to another but there are local bus services and day trip providers that could help out with your time on the west coast.
Transport for Ireland also has a journey planner and links to
Local Link for services information.
Lally Tours and
Galway Tour Company in Galway may be able to help with some tour information while in the city so you and your mom can visit some places while staying in the area.
Hopefully, this will help you decide on your itinerary more.
