Here you can swim in the Atlantic, because they pipe hot water into the ocean. A beach of golden sand has been created and a “pool” has been enclosed nearby, where the water temperature is about 20°C. There are several hot-pots. Refreshments and various services are available at the beach.

The Pearl
An iconic building on top of a wooded hill called Öskjuhlíð, to the southeast of the city centre. Perlan is built on top of five hot water storage tanks and offers fantastic views of the entire city from a viewing platform open to the public and from a rotating restaurant at the top. If the restaurant is too expensive for you (it is for most), there is also a small cafeteria on the same floor as the viewing platform. For the price of admission, one can view and interact with exhibits related to the geology, geological history, and natural history of Iceland. There are some shows related to these topics as well covered with the tickets.
Borgarleikhúsið
Like the national theatre, the city theatre puts on a mix of new Icelandic plays and highlights of international theatre.
Klambratún is a park just east of the city centre on an area which remained farmland while the city was built up around it. The area was later converted into one of the largest public parks in the city and often hosts various events. One of the houses of the Reykjavík Art Museum, Kjarvalsstaðir, is inside the park.
It is safe to say that Jóhannes Kjarval (1885-1972) is the single biggest name in Icelandic painting. Kjarvalsstaðir hosts a collection of his work, as well as hosting other temporary exhibitions.
Norræna húsið
A cultural centre in Vatnsmýri designed by Finnish architect Alvar Aalto, just south of the city centre. Art exhibitions, concerts, poetry readings and other cultural events frequently take place here.
Dómkirkjan í Reykjavík
The church beside the parliament is Reykjavík Cathedral, the mother church of the Church of Iceland, the country's national church and part of the Lutheran denomination. Similarly deceptive in size, it has been beautifully renovated both inside and out to reflect its original 18th-century architecture.
