www.causewaycoast.holiday says; Castlerock starts where the River Bann meets the sea, 5 miles west of Coleraine on the way towards Limavady and Londonderry (see the MAP). It is surrounded by nature in many forms and is within the Benevenagh Area of Outstanding Natural Beauty (AONB). There is a small selection of local shops, tea shops, restaurants, pubs, a Village Green and Community Centre in the heart of the town proper. The excellent championship golf course and the exceptional Blue Flag beaches at Castlerock, Downhill, Benone bring flocks of visitors to the town.The Settlement History of Castlerock can be seen though its remaining architecture.Heritage walking tours around town showcase the late 19th century buildings such as Castlerock Train Station (1853), the Presbyterian Church (1880), Christ Church (1882), Twelve Apostles (1882) and The Villas (1860).  The Railway and Tunnel Construction was constructed around 1845.Above the beach the famous row of houses named the "Twelve Apostles" sit. They are cute inside and quite small, although some have been renovated and extended in the back to take full advantage of the divine location. The award winning, just under a mile long, golden sands, friendly people and breathtaking views are all good reasons to visit Castlerock, not to mention the absolutely fresh air! The castlerock sand dunes are west of the River Bann estuary.  Portstewart Strand is on the other side of the estuary.Castlerock Beach won the Rural Beach Seaside Award in 2014 based on the 'Keep Northern Ireland Beautiful' 15 criteria.
