Soak in geothermal mineral waters against a lava-field backdrop, with a private cabana and spa ritual reserved just for you.
What to expect
A private transfer brings you to the Retreat entrance, where a robe and slippers await. You move through a sequence of steam, sauna, and mineral pools, finishing in the geothermal lagoon itself, its milky blue water steaming against black lava rock. A ritual guide offers silica mud and algae masks along the way, and a quiet lounge area serves light bites and sparkling wine.
Good to know
Reserve months ahead — Retreat Spa slots sell out quickly, especially in shoulder season. Bring extra time for transfers to/from Reykjavik-area ports; confirm return timing carefully against your ship's departure.
