  description: Lahinch is Ireland's surf town—a County Clare beach that has served as the country's surf capital for decades, introducing generations of Irish surfers to the sport. The wave is remarkably consistent for its wild Atlantic location, receiving swells from across the ocean and producing workable peaks for all abilities. The town has embraced its surf identity completely, with quality shops, schools, and a community that revolves around wave-riding culture. The Cliffs of Moher nearby and traditional Irish pubs in town make this a complete surf destination experience.
