Today, take a boat trip and be captivated by the sight of mountain peaks reflected in the glassy waters of Naeroyfjord, a UNESCO World Heritage site. The name Naeroyfjord takes its origins from the Norse god of seafarers and the sea, Njord. The fjord itself, formed by glacial erosion of the surrounding bedrock, is 18 km long and only 250 m wide at its narrowest point, with its depth reaching up to 500 m. Surrounding mountain peaks rise up to 1400 m and waterfalls crash down sheer cliff faces. The boat cruise will finish in the fishing village of Flam, where you can ride the famous railway up to Myrdal (at extra cost). This is one of the most picturesque (and steepest) railway journeys in the country. Alternatively, you could explore on foot to discover nearby waterfalls and ancient moraines. Fishing enthusiasts will love the opportunity to throw a line in the crystal waters, sit back and soak up the serenity (a fishing licence is required and costs around 150 NOK). In the afternoon, catch the bus back to Gudvangen and spend the rest of the day as you please.
