The valley above the beach was once home to a settlement of 'booley' huts used for seasonal cattle herding.
Basking sharks are frequently sighted in the bay between May and July.
The cliffs of Croaghaun, which frame the beach, reach an elevation of 688 meters above sea level.
The beach is periodically subject to significant sand shifts, sometimes completely revealing or burying large rock formations.
Keem Bay was a traditional site for the shark fishing industry, specifically the basking shark, which ceased in the mid-20th century.
The filming of 'The Banshees of Inisherin' utilized the scenic backdrop of the Achill coastline, boosting the beach's international profile.
The waters at Keem are part of the Wild Atlantic Way coastal route, specifically noted for marine biodiversity.
Keem Beach is a remote, horseshoe-shaped sandy cove situated at the western end of Achill Island in County Mayo. The beach is enclosed by the steep slopes of Croaghaun, the third-highest sea cliff in Ireland. The water is known for its clarity and is occasionally visited by basking sharks during the summer months. Access is via a single-track road that winds through the cliffside, offering panoramic views of the Atlantic Ocean. The beach is a designated Special Area of Conservation under the EU Habitats Directive. It features a unique microclimate sheltered by the surrounding peaks. Historically, the valley was the site of a seasonal fishing village known as a booley. It remains largely undeveloped, maintaining its status as a pristine natural environment.
From the high-viewpoint parking area on the cliff road before descending into the valley.
Navigate the final approach road slowly, as it is narrow and features sharp hairpin bends shared with two-way traffic.
Bring a windbreaker regardless of the forecast, as the Atlantic winds can be strong even on sunny days.
Check local tide charts, as the beach area is significantly smaller at high tide.
Do not park on the grass verges along the access road, as this blocks emergency vehicle access and is strictly monitored.
Practice 'Leave No Trace' principles; there are no public trash bins on the beach, so carry all waste away.
