Good view over the harbour in a bit dull surroundings.

If you take a stroll along the Ægisida, where locals all year round and tourists in the summer season like to walk, you’ll at some point come across a tangled shape of bronze rising from a pile of boulders. At first perhaps you won’t even pay much attention to it, with the complicity of the beautiful seascape, especially in the high tide. It took me some time to get used to that weird bronze shape placed in the vicinity of an improvised football field; the very first time, from a huge distance, it looked to me like – I admit it with a little embarrassment – a wolf howling at the sky.

Due to the inflow of warm water from geothermal springs, the bathing temperature in the bay is comparatively pleasant.

Álafoss is a waterfall on the Varmá River in Mosfellsbær in the capital region of Iceland. In 1896, a hydroelectric wool factory was named after this waterfall. Today, only a wool and knitwear shop remains here. Since April 2013,[1] the waterfall and its small 14,000 m² surrounding area have been protected. Downstream of the waterfall, a former swimming pool has been converted into the Sundlaugin (Icelandic: The Swimming Pool) recording studio, where the band Sigur Rós recorded, among other things, their album "( )", the fifth track of which is titled "Álafoss".

An old narrow-gauge locomotive used in the early 20th century to transport materials from the port during the construction of docks and dikes. Restored and displayed outdoors in the port area, it is a small testament to the city's industrial history and a nod to the era when the railway, albeit briefly, was present in Iceland.
