Klukkuholt

The residence itself is not open for tours, but you can walk around the grounds and the nearby coast, and the church is sometimes open to visitors. The surrounding wetlands and shoreline are good for birdwatching, especially in spring and summer. Combine a visit with a stroll or a swim at the local pool.

Hellisgerði is a small, charming park in the middle of Hafnarfjörður, set among dark lava outcrops. Winding paths lead between mossy rocks, flower beds, trees and little ponds, with quiet corners to sit and rest. It feels like a hidden garden tucked inside the town.

Sky Lagoon is a modern geothermal spa on the Kársnes shoreline in Kópavogur, built into the coastal rocks. Its infinity-edge pool looks straight out over the North Atlantic, so soaking in the warm water feels like drifting toward the horizon. There are saunas, a cold plunge and a bar within the facility.
