Dublin to Donegal
 

We're driving from Croke Park, Dublin to Lough Eske, Donegal on Wednesday, March 14, 2018. What's the best route to take? Any suggestions for good stop-off places along the way? (Anything we absolutely shouldn't miss?) What are the most interesting villages? Any recommendations for lunch?

We've never traveled in Ireland before and want to make the most of our time there.

Many thanks for your advise!
