On the fourth floor of Perlan, a large observation deck lies on the top of the hot water tanks and encircles the entire dome to give an amazing 360° view of Reykjavík and the surrounding area.
Admission: Adult: 490ISK. Child (0-15): Free
The Observation deck admission is included in Wonders of Iceland ticket.
The observation deck has 16 information signs that tell you the names of the points of interest on the horizon, from Keilir Volcano on the Reykjanes peninsula in the south, to the world famous Snæfellsjökull glacier that lies on the end of Snæfellsnes peninsula in the north. A large part of the horizon belongs to Esja, the mountain of Reykjavík, in all its glory.
Next to the information signs there are rock samples from geological points of interests, so you can touch lava from the lava fields south of Reykjavík and the soft volcanic rock from the mountains east of the city and the hard basalt columns found north of the Capital area.
Every year, hundreds of thousands of guests come to the top of Perlan to enjoy one of the best views you can get of Reykjavík and its surrounding area.
