There is a rocky headland to the north providing some shelter to the beach. The south end of the beach is very popular with kite surfers.

There is a large public car park and the beach is also served by a bus connection from Dublin City centre. The beach is lifeguarded during the summer months. Lifeguard times are posted on the beach noticeboard.
