South Beach in Greystones, County Wicklow, is a one-kilometer stretch of mostly sandy shoreline that runs south from the town's harbour and marina, lapped by the Irish Sea. The beach is broad and offers a picturesque, family-friendly setting, having earned a Blue Flag designation for clean water annually since at least 2016. For paddlers, the primary access point is from the South Beach car park, which operates with a pay machine. A short path from this car park leads underneath the adjacent DART railway line via an underpass, providing safe and direct access to the sand. The carry distance from the car park to the water's edge is short. The beach is also directly accessible from the Greystones DART station. Amenities for visitors include public toilets and a children's playground adjacent to the park. A specially marked blue path indicates a way onto the beach for wheelchair users and those with pushchairs. The beach has a seasonal ban on dogs from June 1st to September 15th, and dogs must be on a lead at other times.

The overall character for paddling is influenced by its exposure to the Irish Sea. The neighbouring North Beach is known for stronger waves suited to surfing and paddleboarding, suggesting that South Beach may offer somewhat more sheltered conditions, though it remains an open coastline. The water gets deep fairly fast from the shore, a factor paddlers should consider when launching and landing. During the summer bathing season, the beach is monitored by lifeguards, but this service is seasonal. No specific regulations restricting paddling were mentioned. The harbour area to the north, home to the Greystones Sailing Club, presents a nearby destination for paddlers launching from South Beach, offering a blend of leisure and maritime activity to explore. The beach's aesthetic is one of clean sands and well-maintained surroundings, backed by the railway line and the town.
