Just got word of a new web site that has some interesting features. Say you're in Belfast for breakfast and plan to be in Dublin for supper. That's only a couple of hours driving time, so you want to stop at some sights on the way. My Discover Ireland will help you do that.
This web site has a nice graphic interface, is very customizable, and will show you what attractions lay along your route. The sample search from Belfast to Dublin reveals a couple of dozen choices for your journey.
Their database has a lot of small locations, as well as major ones, you you can get as detailed as you like. You can zoom in and out, change your starting and ending points, and even add your chosen attractions to the itinerary. It will show you the distance in both kilometers and miles, driving time, and fuel costs for the trip. You can select or deselect the categories for your attractions, viewing cultural destinations, museums, historic sites, outdoors, and general attractions. Too much detail? Zoom in, or deselect some categories. Too little? Add some back in.
I discovered you need to be specific about your starting point and destination For instance, even though Derry shows on the map where it belongs, putting it in as a starting point showed it some place in Limerick. Apparently, there's a tiny little town there called Derry. If you put Londonderry, UK, it finds the right place.
I put in Wicklow, Ireland, and instead of the town, it placed my destination several miles east. Apparently, you have to specify Wicklow Town to get that instead of the mountains, but Wicklow Town doesn't come up in the autofill suggestions.
So I wouldn't navigate by this, at least not yet, but it gives some marvelous information on what you'll find along the way. Check out My Discover Ireland for your next trip.
