Ilulissat’s rainbow-coloured houses are scattered right at the mouth of a 40km ice fjord. A phenomenal 35 billion tonnes of icebergs pass through here each year, calved from the Jakobshavn Glacier. What’s more, this Unesco World Heritage sight is easily accessible on a short hike from town – though you might prefer to watch bus-sized 'bergs from one of the boat tours plying the bay.The town is next to the sea filled with icebergs from the most active glacier in the world, Sermeq Kujalleq. Excavations show that people have inhabited the area for thousands of years, and it was once the largest town in Greenland. The town is also known for having almost the same number of sled dogs as people: the town is home to 4,600 people and nearly 3,500 sled dogs.
