On Greenland’s west coast, Ilulissat (once known as Jakobshavn) welcomes travelers with astonishing ice scenery and a sense of scale that feels almost otherworldly. The town sits beside Disko Bay, where immense icebergs drift silently past, glowing pink and gold in the Arctic light. The name “Ilulissat” means “icebergs,” and it could not be more fitting. Here, every turn toward the sea offers a fresh view of towering ice forms, each one sculpted by nature into something fleeting and beautiful.

Royal tombs in Lapaha offer a glimpse into the lineage of Tonga’s kings, while village life remains guided by customs that have changed little over centuries.
