Hi bea
We live in Northern Ireland and like to spend short breaks in various local areas of interest. Last October we based ourselves on the Ards Peninsula and rented this fantastic property on the outskirts of a small coastal village called Ballywalter (if I remember, about 15 miles from Portaferry). We chose here as it was about halfway down the peninsula and meant we could choose to go back up towards Newtownards/Belfast on some days or down towards Portaferry on others, without feeling we were spending all our time in the car.
Our boys are 2, 5 and 7 yrs and they loved the whole Ards area. There is a beach and small play park just across from the property we stayed at as well as access to walks through the grounds of the mansion house where it is situated.
Things we packed into our 4/5 day break included:
Ruined Abbey at Greyabbey...boys loved scrambling around this.
Exploris (sea life centre at Portaferry)...small but very good...especially the hands-on tank. Didn't do the ferry this time as have had boys on it before, but still went down to watch it.
Ballycopeland Windmill.
Narrow Guage Railway at Drumawhey Junction.
Ark Open Farm...includes good picnic and play facilities.
Scrabo Tower...drive then short walk to top...great views.
This page from the local council site will give you loads of other details of places of interest and things to do/see. Also, the menu on the website has links to accomodation etc in area and, a 'what's on' section which tells you of anything interesting happening each month.
Phew, all of the above plus Belfast and it's various attractions to..methinks you should come for a month!
I have no doubt you will all enjoy your trip whatever you do...have a fantastic time.
