List of caves in Norway

The Svarthola

A cave or cavern is a natural void in the ground, ^{[1] [2]} specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos, though strictly speaking a cave is exogene, meaning it is deeper than its opening is wide, ^[3] and a rock shelter is endogene. ^[4]

Jarlshola	Melhus	Jarlshola is a small cave in the municipality of Melhus in Trøndelag county, Norway. The cave is near the small farm of Rimul in the village of Melhus. It is thought to be the hiding place of Håkon Sigurdsson (also known as Hákon Sigurðsson, Hákon Earl) and Tormod Kark (or Þormóðr Karkr, the slave of the Jarl) on their last night before the infamous murder at Rimul.
Jordbrugrotta	Rana	Jordbrugrotta [6] is a cave in the upper parts of Plurdalen  [ no ] by the river in Rana municipality in Nordland county in Norway. The cave is named after the farm Jordbrua further down the valley. The cave is situated about two kilometers south of the dam at Kallvatnet. Jordbrugrotta was discovered during the Second World War. [7] In 1949 an attempt to enter via Sprutfossen and into the main system did not succeed. [7]
Pluragrotta	Rana	Pluragrotta is a cave in Rana, Norway. [8] It is the deepest cave in Northern Europe. Most caves in Rana, of which there are some 200, are not suitable for diving. A popular cave diving destination, Pluragrotta attracts more divers than any other cave in Scandinavia. Visibility in the cave waters is high. The cave's passages were formed by the flow of the Plura river over limestone, and the cave system includes marble formations. A number of species have been identified in the cave ecosystem.
Raggejavreraige	Nordland	Raggejavreraige or Råggejávrrerájgge is a cave located in a mountain above the Hellemofjorden in the municipality of Hamarøy in Nordland county, Norway. The cave is located near the lake Råggejávrre, about 2 kilometres (1.2 mi) south of the village of Musken. Råggejávrrerájgge is a limestone cave that has been eroded by this underground river. At 580 metres (1,900 ft) deep, it is the deepest cave in Scandinavia and the only known deep cave north of the Arctic Circle. [9]
