Retreat at Blue Lagoon

Surrounded by milky-blue mineral water, this 62-suite spot feels more like an alternate universe than a luxury hotel. The structure’s hyper-contemporary design flows into the black rock of the Reykjanes Peninsula, and TV-free rooms encourage visitors to gawk at the green-fringed moonscape. Drag yourself away: The main draw remains the private access to Iceland’s famed Blue Lagoon, where you can enjoy an in-water massage while floating in a warm pool far from the selfie-snapping crowds. At the spa, visit the subterranean steam cave and settle in for a three-part scrub using minerals, algae and silica gathered on site. Recharge by settling into a nest chair and letting your mind float away.
