Perlan ("The Pearl") is a natural-history museum crowning Öskjuhlíð hill above Reykjavík, where a glass dome sits atop six geothermal hot-water tanks. A city landmark since 1991, it was expanded into the interactive "Wonders of Iceland" experience and is best known for the world's first man-made ice cave and its northern-lights planetarium. Named a TripAdvisor "Best of the Best" attraction three years running (2022-2024), it remains fully open in 2026. Because it packs Iceland's nature into a single indoor visit, it is an ideal stop for a first day or a bad-weather day.
The world's first man-made ice cave - a 100 m tunnel built from roughly 350 tons of real snow and ice (about -10°C inside), paired with an interactive glacier and climate-change exhibit
Áróra planetarium - a northern-lights show in an 8K domed theatre with surround sound, running indoors regardless of season or weather
Forces of Nature and volcano exhibits - volcanoes, earthquakes and geothermal energy, plus drone footage of the 2021 Geldingadalir eruption and the immersive 'Into the Volcano'
Life-size Látrabjarg cliff replica - a faithful model of one of Europe's largest seabird cliffs
360° observation deck - panoramic views of Reykjavík, the surrounding mountains and sea from atop the water tanks
Good to know
SafetyThe ice cave stays around -10°C even in summer, so bring a warm outer layer and non-slip shoes. The museum sits on an exposed hill where the approach can be icy and windy in winter.
SeasonIn summer (roughly May-July) the midnight sun means you cannot see real aurora in the sky; genuine northern lights appear only on dark nights from September to April. The indoor Áróra planetarium show, however, runs year-round.
RulesBooking tickets online via the official site is cheaper than paying at the door. Planetarium shows run on set times, so check and reserve your slot in advance. Always confirm the latest prices and hours before you go.
MannersStay quiet and dim your phone during planetarium shows, and avoid touching the ice-cave walls to help preserve them.
CautionThird-party resale sites sometimes mark up admission well above face value; buy through the official channel (perlan.is). If taking a taxi, make sure the meter is running.
SafetyThe free shuttle bus has been discontinued (as of 2025). Reach Perlan on foot (about 30 minutes / 3 km from downtown), by city buses 13 and 18, or by car with free parking outside. In winter, daylight is short and it gets dark by early afternoon, so plan your timing accordingly.
Practical info
Perlan sits on Öskjuhlíð hill (105 Reykjavík), about a 30-minute walk from downtown; city buses 13 and 18 stop nearby and free parking is available outside. Exhibitions are open daily roughly 9:00-21:00 (shop, restaurant and café keep shorter hours), but confirm exact opening times and ticket prices on the official website before visiting.
