Wind down with a soothing dip in the pastel waters of the Blue Lagoon. Heated by geothermal vents, these man-made pools are the ideal place to rest and relax, just outside of Reykjavik, and with included transportation, there's no need to stress out over how to get there.

Journey south from Reykjavik and out toward the Reykjanes Peninsula's Blue Lagoon, where natural hot springs are surrounded by craggy piles of black volcanic rock. Change into your favorite swimsuit and dip into waters that have been pumped up from depths of up to 6,000 feet (2,000 m). Use the lagoon's soft silica bottom as a natural exfoliant or just float around, taking in sweeping views of Iceland's rugged interior.

Consider grabbing a refreshing drink from the swim-up bar or indulge in a spa treatment or massage. When you're ready to return to Reykjavik, hop in the onsite shuttle and enjoy the comfortable ride back to the city.
