R121 road (Ireland)

The R121 is a regional road in Ireland. It is located entirely within County Mayo, on Achill Island. The road forms a loop off the R319, which is the primary road serving Achill.

The R121 begins at a junction with the R319 near Achill Sound. From there, it travels northwest, passing through or near several small settlements including Bunnacurry, Dooagh, and Keem Bay. Keem Bay, a popular tourist destination, is located at the westernmost point of the R121. The road then turns east, continuing through more sparsely populated areas on the northern side of Achill Island. Finally, it rejoins the R319 northeast of Achill Sound, completing the loop.

The R121 is a single-carriageway road. Significant portions of the road are narrow and winding, particularly in the vicinity of Keem Bay. Travelers should exercise caution and be prepared for slow speeds and limited passing opportunities. The scenic views along the R121, particularly of the coastline and surrounding landscape, are considered a major attraction of the route.

The road's length is approximately [Insert verifiable road length here, if available]. Information on road maintenance and improvements would be managed by the relevant local authority, Mayo County Council.
