Visitors can purchase a ticket for the observation deck only, or for the Glaciers and Ice Cave exhibition at the Perlan Museum, which includes access to the observation deck. The Glaciers and Ice Cave exhibition features a 328-foot (100-meter) man-made ice cave that replicates those found in nature as well as an interactive exhibit on glaciers. Other exhibitions include a planetarium and the Land, Coast, and Ocean exhibit, which features a cliff replica, virtual fish tank, and simulated earthquake.
For an extra special experience, opt for an after-hours tour of the museum, during which you’ll be guided through the ice cave and glacier exhibition after the daytime crowds have gone. Visitors can also dine at Perlan’s glass-dome Út í bláinn restaurant, offering excellent views over Reykjavik and beyond—and if you’re lucky, perhaps even the Northern Lights.
