Sweeneyâs bar of Claddaghduff will be your first port of call. Thereâs a nice shop there and a post office, beer, wine, petrol, diesel, gas and briquettes. From there you can check the tides and take in the view. Omey will come alive before your eyes. The size of the strand will become apparent if the tide is open. Be careful with the tide though, it can close with remarkable speed. Cross the strand by car or foot to enter Omey Island.
