Visitors to Reykjavík are thrilled by the pure energy at the heart of Iceland’s capital city: be it from the boiling thermal springs, the natural green energy, or the lively cultural scene and fun-filled nightlife. The world’s northernmost capital, it's framed by the majestic Mount Esja, which keeps a watchful eye on the city, and the blue waters of Faxaflói Bay. On a sunny day, the mystical Snæfellsjökull glacier appears crystal-like on the western horizon, while mountainous moonscapes spread to the southeast.

Attractions span beautiful public libraries, fascinating museums and plenty of sports. Boston is destined to grow ever more beautiful as more and more of the ungainly elevated highways are replaced with lush parks.
