The Jakobshayn Glacier calves icebergs into Disko Bay – a popular whale-watching spot on Greenland holidays. Trek up Avangnardlit for magnificent views or visit Uummannaq with its colourful mountainside homes. Northeast Greenland is the world’s largest national park. Epic fjords bordered by 2,000m high mountains shelter narwhals and walrus. Vivid turquoise glaciers splinter into the 100m-high 'Iceberg Alley' – and the Northern Lights.
