Take the N11 to Wicklow Town. Drive past Heaton's, Lidl and Tesco (on your left) and continue into the main street of Wicklow Town. Where the road forks (there is a 'triangle' of fenced-around trees in the middle of the road), turn Left.
Continue through the small crossroads until you see The Bridge Tavern immediately coming up on your Right. Turn Right just at the tavern. (If you miss the right turn and drive over a bridge, come back around and turn Left at the Bridge Tavern.) Continue along the road with the harbour on your left.
You will see Hopkins Homevalue Hardware coming up on your Right. Turn Right immediately after Hopkins Homevalue Hardware. Take the next Left. Almost immediately you will see, on your Right, two Big grey Gates. The SOL centre is in here. Parking is available outside the venue, or in the area on your left just as you turn up from Hopkins. You can also find parking if you just continue up the road (keep Left at the fork) for about 100 yards. There's a parking area on the left overlooking the bay.
