Patrick Taggart: A beautiful, almost deserted, south facing bay about 0.6km across, framed at either end by rocky causeways. A sandy cliff above the sandy beach provides nesting for sand martins. The grassland beyond is rich with wildflowers. A great place for skylarks.
Don't swim out of the bay eastwards; you will get caught up in strong currents entering/leaving Strangford Lough. Swimming over the reef at the east end of the bay is fun but choppy. Don't climb on the unstable cliffs
Kate Rew: Recommended by Rachel Smith: Best part of a mile long beach and you swim off a nature reserve. Starfish underneath, crabs that wave at you and seals in abundance as you swim up the channel... It's an empty beach, and crystal clear water and you can swim at any tide.
It's a nature reserve so to get to the swim you have to do a beautiful 20 minute walk: it's a wild swimmers dream.
If you swam too far out of the bay (like a kilometre) you could get into difficulties with currents .
