Knock and Killantringan Bays Beach is a rural continuous sandy beach that spreads to over 1 km (0.6 miles). The southern side of Killantringan Bay transitions from a sandy beach to a rock platform. It is one of the widest beaches on this stretch of coastline and reaches a width of about 200 metres (656 feet) in places. On the headland to the south lies Killantringan Lighthouse, which was built in 1900, but now closed. In the bay across it, at low tide, you can observe the wreck of the Craigantlet; a container vessel that ran aground here on 26th February 1982. The beach can be accessed by car from the B738 with parking off the road to the lighthouse. Or there is a fine coastal footpath to the beach from Portpatrick three miles to the south.
