1. Perlan's 360-Degree Viewpoint
Perlan sits on Öskjuhlíð hill, and its observation deck offers a 360-degree view over Reykjavík. It's a strong pick for a wide city panorama, with the chance to spot fireworks popping up across different neighborhoods. Perlan also has indoor exhibitions, including an ice cave and an aurora planetarium show, if you want a warm activity before heading out. Its New Year's Eve gala is a separate ticketed event.
