Mývatn () is a shallow lake situated in an area of active volcanism in the north of Iceland, near Krafla volcano. It has a high amount of biological activity. The lake and the surrounding wetlands provide a habitat for a number of waterbirds, especially ducks. The lake was created by a large basaltic lava eruption 2300 years ago, and the surrounding landscape is dominated by volcanic landforms, including lava pillars and rootless vents (pseudocraters). The effluent river Laxá is known for its rich fishing for brown trout and Atlantic salmon.

Krafla () is a volcanic caldera of about in diameter with a long fissure zone. It is located in the north of Iceland in the Mývatn region and is situated on the Iceland hotspot atop the Mid-Atlantic Ridge, which forms the divergent boundary between the North American Plate and the Eurasian Plate. Its highest peak reaches up to and it is in depth. There have been 29 reported eruptions in recorded history.

Herðubreið (, broad-shouldered) is a tuya in the northern part of Vatnajökull National Park, Iceland. It is situated in the Highlands of Iceland at the east side of the Ódáðahraun () desert and close to Askja volcano. The desert is a large lava field originating from eruptions of Trölladyngja and other shield volcanoes in the area. Herðubreið was formed beneath the ice sheet that covered Iceland during the last glacial period.

Öskjuvatn (, "Askja Lake") is a lake in the Highlands of Iceland. Its surface area is about 11 km2. With a depth of , it is the second-deepest lake in Iceland after Jökulsárlón.

Situated in the Ódáðahraun lava field, Trölladyngja () is the biggest of the Icelandic shield volcanoes, reaching a height of above sea level, and rising almost above the surrounding desert and lava fields. It part of the Bárðarbunga volcanic system and has a volume of with some extensive lava flows to the north of Bárðarbunga.

The Dimmuborgir area is composed of various volcanic caves and rock formations, reminiscent of an ancient collapsed citadel (hence the name). The dramatic structures are one of Iceland's most popular natural tourist attractions.

Theistareykjarbunga (Þeistareykjarbunga, ) is a shield volcano in north-eastern Iceland with two fissure vents called Þeistareykjahraun and Borgahraun , and two cones: the Stórahversmór and the , Stóravíti . They both are currently extinct, although there is evidence suggesting the potential for activity such as recent localised uplift and seismicity. The multiple vents make up the Theistareykir (Þeistareykir) volcanic system, with more recent evidence that the former classification as a shield volcano is better considered an embryonic central volcano with associated fissure swarm, as rhyolite

Fremrinámur () is a volcano with a located on the basalt plateau in Iceland. It is at the junction of the Mid-Atlantic Ridge and the Greenland–Iceland–Faeroe Ridge. It is one of five volcanic systems found in the axial rift zone in north-east Iceland. Its height is about .

Kollóttadyngja () is a shield volcano in the Ódáðahraun lava-field in Iceland. Its height reaches 1,177 metres, and it has a diameter of 6–7 km. The summit crater is 800 metres in diameter, but only about 20–30 metres deep. In its centre, there is a bowl about 150 metres in diameter with a depth of about 60–70 metres.

The Dyngjufjöll is a volcanic mountain range in the northeast of Iceland which belongs to the Askja volcanic system. It is part of the Vatnajökull National Park, and contains the Askja caldera.
