As you sail through this UNESCO World Heritage Site, it's easy to imagine you're in a Norse fairytale. The mountains soar above you, up to 1,700 metres. The water drops to depth of 260 metres beneath your feet. Even the waterfalls have intriguing names, such as the Suitor, the Bridal Veil and the best-known, the Seven Sisters. You sail past all three waterfalls, so have your camera at the ready. And if you have a sense that there's something familiar about Geirangerfjord's scenery, it was the inspiration for Disney's movie, Frozen.
