Hveravellir geothermal area is a small nature reserve and a tourist centre located at 600 m (2,000 ft) at the Kjölur mountain route between the glaciers Hofsjökull and Langjökull, in central Iceland.

The main geothermal activity is at the northern border of the large lava shield Kjalhraun [ˈcʰalˌr̥œyːn].

Sinter and geyserite is prominent, forming low and wide domes around active or extinct geothermal centres.

In Breiðimelur [ˈpreiːðɪˌmɛːlʏr̥], north of the main thermal area, there are several steam vents where people have baked black rye bread in the hot ground.

[4] The geothermal field is a tourist attraction; a bath can be taken in the pool created by damming the hot water stream in 1950.
