Greystones South Beach is a Blue Flag beach on the Wicklow coast, approximately one kilometre in length, composed of a mix of sand and shingle. It is situated adjacent to Greystones Harbour and is easily accessible from the town and the Greystones DART station. A dedicated car park is available, though it is paid parking. For paddlers launching from shore, there is a wheelchair-accessible boardwalk leading to the beach, which facilitates the carry of equipment. The beach is lifeguarded during the official bathing season, which runs from June 1st to September 15th. Public toilets are present, and a children's playground is adjacent. The water quality is consistently monitored and has an EPA classification of Excellent. The beach is a popular, family-friendly destination with a lively town atmosphere and cafés nearby.

For paddlers, the primary consideration is the exposure to the open Irish Sea. The beach has no surf, indicating generally calm conditions suitable for kayaks and stand-up paddleboards, though this also means it is exposed to wind. The launch is across a sandy and pebbly shore, with the carry distance dependent on the tide. The beach is a serious location for bass fishing, particularly in surf and coloured water, which suggests that conditions can change and that paddlers should be aware of anglers, especially at night. A specific hazard is the potential for significant weed accumulation in the water, which can be dense and pervasive, making navigation difficult. The beach is used for organised paddling events, including SUP sessions, confirming its suitability for the activity. A key nearby feature is the start of the famous cliff walk to Bray, offering dramatic coastal views from the water. Paddlers can explore the coastline north towards Bray Head or south along the Wicklow coast, with the sheltered area of The Cove in Greystones being a potential nearby destination.
