Claddaghduff is the kind of place where you arrive because you heard about the island, not because you were passing through. It sits on the north Connemara coast, a scatter of houses above a rocky beach, and the reason you came — Omey Island — lies 1 km offshore.
At low tide, the island is connected. The strand uncovered by water becomes a quarter-hour walk to Tempall Fheichin, a ruined church from the 7th century, and the holy well beside it. The island has been inhabited since prehistoric times. A few people still live there — houses perched above the rocks, a handful of permanent residents whose neighbour is the Atlantic.
In August, the horse race takes over. Riders line up on the strand and run the beach, the way they have for generations. It is not a formal event with grandstands. It is riders, horses, a beach and wind.
The scenery is the point. Rocky coastline, bog inland, the Atlantic as the third element. Come at low tide, walk the strand, sit at the church and look west. There is nothing to buy here, nowhere to eat. That is the whole appeal.
The reason to come back. The things every local will eventually tell you about, usually after the second pint.
Wear waterproofs. Bring a sandwich. Tell someone where you're going if it's the mountain.
There is no bad time. There are different times.
The island is quieter, the weather is milder than you'd expect, and you can time the walk without summer crowds.
August brings the horse race. Book a bed if you want to stay through it. Otherwise summer is fine, just windier and wetter.
The shoulder. The light is clear, the water is more reflective, and the wind gives the bog-walk teeth.
The weather is serious. The strand walk is still possible, but the conditions change fast. Come prepared.
