About 20mins from Dublin, head south on the M50 until it merges into the M11 / N11, approximately 6 kms south take exit 7 for Greystones which brings you on to the R768 after approximately 2 kms you will come to the R761, take this south to Greystones (3kms). In Greystones take the R762 towards Greystones Harbour – stay on this coast road for a further 300m until you get to Marine Road / the Carrig Eden. The entry point for this shore dive is from the steps next to the small stony beach. At off-peak times you should be able to get on street parking close by.
The sea bed and beaches around here consists mainly of (grey!) stones, so visibility can be pretty good by east coast standards.
Setting out from the steps below the Carrig Eden, take a south easterly course for about 10 mins, at which point you should reach a reef in about 8m to 10m. A southerly tide here can cause you to miss the reef, in which case you should turn back and explore the more sheltered area closer to the shore where there is plenty to see in depths of up to 6m (at high tide).
The nearest RNLI station is Wicklow, which can be contacted at 0404-67163, the Irish Coast Guard can be contacted by phoning 999 or 112.
