Bothar nA hAillite, "the road of the cliffs", is an ancient green road that threads the Burren's bare limestone pavement above the Atlantic just outside Doolin, Co. Clare.
Bothar nA hAillite is an old route known for its limestone pavement and ecosystems, reached off the R479 near Ballyryan/Oughtdarra in the Burren. The surface is rugged and uneven, so wear sturdy shoes and treat it as a scenic out-and-back.
The route opens onto sea and cliff views near Doolin; Doolin Pier and Crab Island, with its 19th-century coastguard hut ruins, lie just offshore.
The Burren is home to rare plant species and wildlife, and the area is a draw for photographers; spring gives the best display of wildflowers.
Nearby Doolin Pier is a Geosite where you can walk on the limestone pavement and explore rock pools; ferries to the Aran Islands and Cliffs of Moher cruises run daily through the summer.
