Relax in Iceland's idyllic Blue Lagoon and enjoy an evening Northern Lights cruise from Reykjavik. After an afternoon bathing in the warm, turquoise waters of the geothermal lagoon, take a 2.5-hour night cruise to look for nature's magical light show. With luck on your side, catch a display of the red, blue and green lights as they dance in the dark skies over the sea. Learn about the lights from the onboard commentary as you watch from deck.
