Check the tide tables before you go: the path across the causeway is only passable at low tide. The area is a nature reserve and is closed to visitors during the bird nesting season in early summer, so plan for the rest of the year. It's a superb place for sunset and, on clear winter nights, for watching the northern lights.

Whales of Iceland is an indoor exhibition in the Grandi harbour district, where more than twenty life-sized whale models hang and stand through a darkened hall. Walking between them, you can appreciate just how enormous creatures like blue whales and sperm whales really are. An audio guide explains the species that visit Icelandic waters.

The most popular route leads up to a stone landmark, around the halfway mark, and takes a couple of hours. A more demanding path continues toward the summit ridge, with steep, loose sections that should be avoided in poor weather or when there is snow. Bring water, windproof layers and sturdy boots, and check the forecast before you set off.
