Cross the Arctic Circle and go whale watchingHúsavík is a pleasant small town famous for its whale-watching opportunities, and we’ll be calling here in the morning. The town looks out over Skjálfandi bay, which enjoys visits from humpback and minke whales, white-beaked dolphins, harbour porpoises and occasionally blue whales. If you’re lucky, you might see one or more of these giants at sea, and you can learn more about them at Húsavík’s Whale Museum. Húsavík is also regarded as the gateway to many of the highlights of the north, including Jökulsárgljúfur National Park, the waterfall of Dettiffos, and the horseshoe-shaped valley of Ásbyrgi, which according to Icelandic myth, was made by the eight-legged horse of Odin. Later, we’ll sail along the coast of Grímsey island without landing, passing across the Arctic Circle as we do so, before continuing to our next destination.
