Reykjavik
The world's northernmost capital and the gateway to almost every Icelandic itinerary — Hallgrímskirkja's spire dominates the skyline, the Harpa concert hall fronts the harbour, and the geothermally-heated outdoor swimming pools (Sundhöllin, Vesturbæjarlaug, Laugardalslaug) are the city's social hubs all summer. Most central hotels run on the Nordic Swan or Green Globe certification and tap directly into the municipal geothermal hot-water grid.
