Isolated, rugged, and breathtakingly gorgeous, Skellig Michael in Ireland is like an image you could only conjure up in your imagination. In fact, it's so unreal that it has actually been a filming location for blockbuster fantasy and sci-fi films, including Star Wars. The site was discovered by monks many years before any of us were born and they chose it specifically because of how difficult it is to access. They certainly weren't messing about - Skellig Michael is so hard to reach that you'll be risking your life by attempting the journey.
As a UNESCO World Heritage Site, this beautiful, craggy rock has attracted thousands of tourists. But the only way to get there is by taking a one-hour boat ride across rough ocean, with very high waves. Once you get there, the slippery thousand-year-old stairs are another hurdle.
