Arguably Ireland's most beautiful beach, hidden at the end of a dramatic cliff road on Achill Island. The sheltered horseshoe bay has incredibly clear turquoise water, white sand, and basking sharks occasionally visible offshore.
Keem Bay sits at the far western end of Achill Island in County Mayo, a horseshoe-shaped cove enclosed by the steep green shoulders of Croaghaun and Moyteoge Head. The sand is fine and pale, and because the bay is sheltered on three sides, the water clarity is exceptional, taking on a turquoise-to-emerald colour on sunny days that is unusual for the west of Ireland. The cove is compact rather than a long open strand, giving it an intimate, enclosed feel, and the surrounding cliffs block much of the prevailing wind, so conditions are calmer than the exposed Atlantic beaches elsewhere on Achill. The atmosphere is quiet and scenic rather than a party beach, drawing families, swimmers, and hikers using the cliff road as a scenic stop or as the starting point for the walk up Moyteoge Head. Amenities are minimal: there is a car park at the top of the access road and a seasonal lifeguard on duty during the main summer season, but no cafe, kiosk, or permanent toilet block at the beach itself. Basking sharks are occasionally spotted offshore in early summer, and the bay was historically used for shark fishing. The approach is via a narrow, winding cliff road from Keel that offers dramatic views before descending to the car park directly above the beach; there is no public transit to the bay, so a car is effectively required.

When to visit
June through August brings lifeguard cover and the calmest seas, while a weekday visit outside peak midday hours avoids the tour-bus crowds on the cliff road.
Accessibility
The car park sits directly above the beach with a short slope down to the sand; there is no paved path, ramp, or beach wheelchair, so the descent is difficult for wheelchair users or those with limited mobility.
