Lakagígar is a row of more than 130 craters over 29 km long in Vatnajökull National Park, about 35 km north-west of Kirkjubæjarklaustur, formed in the Skaftáreldar eruption of 1783–84, which led to famine in Iceland. Trails start at a ranger station by the mountain Laki, reached by four-wheel drive on the F206 highland road, open only in summer.

Kirkjugólf, Icelandic for "church floor", is a flat surface of about 80 square metres at the edge of Kirkjubæjarklaustur, formed by the tops of basalt columns worn smooth by the sea and by glaciers. The many-sided stones look like a paved floor, although no church ever stood here; the site is protected as a natural monument.

The Akureyri Botanical Garden (Lystigarður Akureyrar) lies on the hillside south of the town centre, about 85 km south of the Arctic Circle. The public park opened in 1912 and the botanical garden in 1957; its 3.7 hectares hold lawns, flower beds, a pond and plant collections that include around 400 Icelandic species.

Akureyrarkirkja is the Lutheran church of Akureyri, standing on a hill above the town centre. Designed by Guðjón Samúelsson and completed in 1940, it has two stepped towers, a 3,200-pipe organ, reliefs by Ásmundur Sveinsson on the nave balcony and an altarpiece from 1863 by Edvard Lehmann.

Svartifoss is a waterfall in Skaftafell, in Vatnajökull National Park, that drops over a cliff of dark, mostly hexagonal basalt columns. The columns formed about 300,000 years ago when lava filled an old riverbed and split as it cooled. It is reached on foot from the Skaftafellsstofa visitor centre on trail S2, which also passes Hundafoss and Magnúsarfoss.

Goðafoss is a waterfall on the river Skjálfandafljót in northern Iceland, beside the Ring Road between Akureyri and Lake Mývatn. The river drops 12 metres over a curved ledge about 30 metres wide, and paths and viewpoints on both banks lead to the edge of the falls and down towards the water.

Skaftafellsjökull is an outlet glacier of Vatnajökull, a tongue about 10 km long between the Skaftafellsheiði heath and the mountain Hafrafell in Vatnajökull National Park. The S1 trail, a 4.1 km loop from the Skaftafellsstofa visitor centre, leads to the meltwater lagoon at its front past moraines and kettle holes. Going onto the ice needs a guide.

Svínafellsjökull is an outlet glacier of Vatnajökull in Öræfi, about 7 km east of Skaftafell, flowing down from Öræfajökull between steep slopes. Its broken tongue ends in a small meltwater lagoon. In 2018 the authorities warned against trips onto the glacier after cracks were found in the Svínafellsheiði slope above it; going onto the ice needs a guide.

Hofskirkja is a turf church at Hof in Öræfi, about 18 km south-east of Skaftafell. Páll Pálsson from Hörgsdal built it in 1883–85 with stone side walls, a turf-covered roof and timber gables; it is 9.8 m long. The National Museum of Iceland took it over and rebuilt it in 1953–54, and it is still the parish church, set in a churchyard with raised graves.

The Húsavík Whale Museum occupies the town's former harbourside slaughterhouse, built in 1931 and opened as a museum in 2002. On two floors it presents the whales of the North Atlantic, their ecology, strandings and the history of whaling and whale watching in Iceland, with 13 real whale skeletons on display.

Húsavíkurkirkja is a wooden church above the harbour of Húsavík, built in 1907 to designs by the Icelandic architect Rögnvaldur Ólafsson. The cross-shaped building is painted white with red trim, under a green roof and a pointed spire. It still serves the parish for services, baptisms, weddings and funerals.

Skútustaðagígar is a group of pseudocraters on the southern shore of Lake Mývatn, beside the farm and church of Skútustaðir. They formed about 2,300 years ago when lava flowed over the lake and its wetlands, and steam explosions built grassy cones with no vent beneath them. A walking path loops through the craters around the Stakhólstjörn pond.

Fjallsárlón is a glacier lagoon on Breiðamerkursandur, about 10 km west of Jökulsárlón near Route 1. The Fjallsjökull glacier, an outlet of Öræfajökull, calves into it, so smaller icebergs float on the water. Since 2017 the lagoon has been part of Vatnajökull National Park; great skuas nest on the shore in early summer.

Dimmuborgir is an area of lava pillars, arches and caves east of Lake Mývatn, formed about 2,300 years ago when a lava lake drained away and left behind hollow columns that had formed over boiling marshland. Marked trails of different lengths lead through the formations, including to the arched cave called Kirkjan.

Grjótagjá is a small lava cave with a geothermal pool, on a fissure of the plate boundary about 2 km south-east of Reykjahlíð by Lake Mývatn. It was a bathing place until the Krafla fires of 1975–84 heated the water to about 60 °C. The cave is on private land and bathing is not allowed; visitors look in from the entrance and walk along the rift above.

Hverfjall, also called Hverfell, is a tephra ring volcano east of Lake Mývatn that formed in an eruption about 2,500 years ago. Its black crater is roughly 1 km across. Two marked paths, from the north-west and from the south, lead up to the rim, and walking on any other route is forbidden.

Earth Lagoon Mývatn, known until its renaming as the Mývatn Nature Baths (Jarðböðin), is a geothermal lagoon at Jarðbaðshólar east of Lake Mývatn, opened in 2004. Water from the Bjarnarflag borehole emerges at 130 °C and is cooled to 36–40 °C; it is alkaline, rich in sulphur and not chlorinated. There is also a steam bath.

Hverir, also called Hverarönd, is a high-temperature geothermal field at the foot of Námafjall, east of Reykjahlíð and Lake Mývatn. Steaming fumaroles, boiling mud pots and sulphur deposits colour the ground yellow, grey and red, and roped paths lead between them; the smell of hydrogen sulphide is strong.

Jökulsárlón is a glacial lagoon at the foot of the Breiðamerkurjökull glacier, beside Route 1 between Skaftafell and Höfn. It began to form in the 1930s as the glacier retreated and is now more than 280 m deep. Icebergs calve from the glacier and drift towards the short river to the sea; a 1.2 km trail leads from the car park to the Helguhóll ridge.

Krafla is a volcanic caldera about 10 km wide north-east of Lake Mývatn, some 11 km from Reykjahlíð. Visitors walk to Víti, an explosion crater from the Mývatn fires of 1724–29 holding a green lake, and the Leirhnjúkur lava field, where trails cross steaming ground and lava from the Krafla fires of 1975–84.
