Fanad Lighthouse

Situated along the mouth of Lough Swilly, Fanad Lighthouse was first lit in 1817 (on Saint Patrick's Day, no less). Now, it's considered by many to be one of the world's most stunning lighthouses. For the best views, climb the 76 steps to the top of the tower. Guided tours are also available, as are overnight accommodations housed in three beautifully restored lighthouse keeper homes.
