Visit Reykjavik's beach
In Iceland the sea is normally far too cold to tempt swimmers, but at Nautholsvik bay in Reykjavik, a thermal beach has been created, where natural hot water flows out into the sea, and you can frolic in the waves as if you were in the Mediterranean!
A beach of golden sand has been created and a "pool" has been enclosed nearby, where the water temperature is about 20ºC. Refreshments and various services are available at the beach. Nautholsvik beach is open daily 10:00 to 20:00 from 16th May until 31st August.
