Norway has no shortage of fjords, but the longest and deepest of them is the Sognefjord. It stretches over 200km inland from the ocean, and the tiny town of Flåm lies at the end of one of its most scenic stretches. The best way to see the fjords is by boat, but before we got to that there was time for a taster with a walk along the waterside in Flåm. In one direction, steep cliffs rose out of the water, with trees clinging perilously to sheer rock faces. Just inland and away from the tides, a huge pool of perfectly flat water reflected the mountains and sky like a mirror. Then in the other direction a boardwalk led along the shoreline, past a wooden pier jutting out into the water and a line of red cottages, each with a boat tied out front. It was like walking into a brochure from the Norwegian tourist board, and this was just the preview.
