Giant's Causeway in May

Early morning or late afternoon. The tour buses arrive between 11am and 3pm, turning the main viewing area into a photo queue. Get there by 9:30am and you'll have the stones mostly to yourself. April through September offers the best weather, but July and August are tourist hell. May and September hit the sweet spot — decent weather, fewer crowds, and the cliff-top flowers are in bloom. Winter has its own magic. The storms create massive waves crashing against the causeway, and you'll practically have the place to yourself. But dress for Arctic conditions — the wind chill is no joke. Avoid weekends if possible. Saturday crowds are insane, especially when cruise ships dock in Belfast. Tuesday through Thursday are consistently quieter. Check the tide times. Low tide exposes more of the causeway stones and makes for better photos. High tide brings the waves right up to the columns — dramatic but you can't walk out as far.
