Looking up the Ring Of Kerry and seeing this on Wikipedia
The Ring of Kerry (Irish: Mórchuaird Chiarraí) is a 179-kilometre-long (111-mile) circular tourist route in County Kerry, south-western Ireland. Clockwise from Killarney it follows the N71 to Kenmare, then the N70 around the Iveragh Peninsula to Killorglin – passing through Sneem, Waterville, Cahersiveen, and Glenbeigh – before returning to Killarney via the N72.
The Ring is a popular day trip and numerous bus companies offer circuits during the summer months. As the narrow roads make it difficult for tour coaches to pass one another, all tour buses run in an anti-clockwise direction, travelling via Killorglin first.
Some recommend that car owners travel in the opposite direction, going first to Kenmare to avoid delays caused by tour buses. Others advise travelling counter-clockwise to avoid having to pass the buses.
In 2008 satellite navigation systems were blamed for directing bus drivers in a clockwise direction around the route.
