Directions from Belfast By M2 and M5 to Whiteabbey and Carrickfergus, and then on towards Whitehead. At Whitehead, you will see signs for Islandmagee; ignore them and keep driving in the direction of Larne. A few miles beyond Whitehead, you will come to a junction. Here, Ballycarry is to the left, and the sign to the right says Portmuck. This is Lower Island Road. Follow it (B90) over the bridge until you come to a crossroads, with a Vivo store on the right.
Turn left at this first crossroads (with the Vivo store) and keep going straight for about five miles. This road – called the Low Road – will lead mostly upwards to the highest point on the island. As the road starts to descend, you will get your first full view of Brown’s Bay, the Glens of Antrim and possibly the Mull of Kintyre. As soon as you do, look out for a road to the right (just past two houses on the right); this is Lunnon Road – it is signposted to Portmuck & Seabreeze.
Drive up it to the end (about half a mile). You are now in the village of Mullaghboy. Turn left, and within a minute you will be at the end of the village. There is a road to the left going to Brown’s Bay, do not take it. Take the road straight ahead which will have a cul-de-sac sign on it and will be signposted ‘Portmuck’. It winds all the way down a steep hill to the harbour. There are a number of sharp bends. At the last of these before the stretch down to the harbour there is an unpaved lane to the right. Go up the lane to the first concrete driveway on the left. Seabreeze is the two-story white house at the top of this driveway.
If by any chance you are confused, keep going down to the car park at the harbour, turn round and come back up the road. At the first right hand bend, you will see an unpaved lane to the left. Follow it for about two hundred yards to a concrete driveway on your left; our house is the only one at the top of the concrete lane.
Directions from Larne: Follow the shore road towards Carrickfergus (not to Belfast!) until Ballycarry. Where the right turn goes off to Ballycarry, turn off to the left to Islandmagee. This is the Lower Road mentioned above. From here, follow descriptions above.
