At Forest Lagoon, we believe that truly unforgettable experiences are created through thoughtful details. Nestled in the heart of Vaðlaskógur forest and overlooking one of Iceland’s longest fjords, Eyjafjörður, this geothermal spa offers a rare blend of serenity, nature, and modern comfort. Surrounded by birch and pine trees, guests are invited to slow down, breathe deeply, and connect with the calming energy of the forest. The lagoon features two geothermal pools. The larger pool (530 m²), kept at a soothing 37°C (98.6°F), includes three swim-up bars and a convenient indoor entrance. The smaller pool (330 m²) maintains the same relaxing temperature, offering a quieter space to unwind. Enhance your experience in the Finnish-style dry sauna, where temperatures reach around 80°C with low humidity. From here, enjoy panoramic views of Eyjafjörður and the surrounding mountains. For the ultimate refresh, step into the nearby cold pool, cooled to 11°C (51.8°F), and discover the invigorating benefits of hot and cold contrast bathing. Complete your visit at the Forest Bistro, a wood-clad dining space with fjord views and a cozy indoor fireplace
