We have 3 days to spend in the Irish countryside in July. We will be leaving Dublin and would like to work our way South, West, and North to Galway. Do you have suggestions about places to see and also the best way to travel? Is driving fairly easy? We were thinking of maybe hiring a guide/driver. Do trains serve you in this area? We like beautiful landscapes, hiking, visiting historic castles, as well as other spots of historic or natural interest. Thank you for your ideas.
