Blue Lagoon & Reykjanes Peninsula

The Blue Lagoon and Reykjanes Peninsula lie 50-80 km from Reykjavik, about 45-60 minutes by rental car via Route 41 and 43. The Flybus/Airport Direct shuttle ($25-35) also serves the Blue Lagoon directly, and organised tours combine the spa with the surrounding sights. Reykjanes is a young volcanic peninsula with geothermal fields, lava fields, and dramatic coastal cliffs. The main draw, the Blue Lagoon geothermal spa near Grindavík, is a milky-blue silica-rich pool fed by nearby geothermal power plant runoff; tickets must be booked well in advance, as walk-ins are rarely accepted. Nearby free sights include the Bridge Between Continents, a footbridge over a fissure marking the North American and Eurasian tectonic plates, the Reykjanesviti lighthouse and sea cliffs at the peninsula's southwestern tip, the Gunnuhver geothermal area with roaring mud pots and steam vents, and the Seltún geothermal field beside Kleifarvatn lake. A typical day starts with the free natural sights — Bridge Between Continents, Gunnuhver, and Reykjanesviti in the morning — then continues to Seltún and Kleifarvatn around midday, saving the Blue Lagoon for last in the afternoon or early evening, since driving is not advisable immediately after soaking. The peninsula is open year-round; the geothermal areas are steam-heavy and can be visited in any season, though winter storms occasionally close coastal roads near the lighthouse. Food options are limited on the peninsula itself, so most visitors eat at the Blue Lagoon's Lava Restaurant or Café Ecru, or stop in Grindavík or at Keflavík en route.
