Hallgrimskirkja
Bus 16 plus a 10 min walk, or 20 min on foot from Harpa
The rocket-shaped church that owns the skyline, its design borrowed from cooling lava columns. The church itself is free. The tower lift, about 1,400 ISK, buys you the definitive view over the rainbow rooftops.
Free to 1,400 ISK
