The bay forms a sheltered horseshoe, a mile-long curve set against Errisbeg’s soft, brown slopes. Its twin, Gurteen Bay, rests just beyond a narrow neck of dunes. Gurteen also has a pale shore, but we find it often emptier, making it suitable for a swim, particularly when Dogs Bay draws more strollers.
The water permits a ten-minute swim in June and September; July and August extend that to twenty. Given the Atlantic wind and the absence of shops, plan for a full afternoon.
