Since 2008, Iceland has three national parks. Prior to 2008 there were four national parks in Iceland; in that year Jökulsárgljúfur and Skaftafell were merged and incorporated into Vatnajökull National Park.
Jökulsárgljúfur National Park is a former national park situated in the north of Iceland around the river Jökulsá á Fjöllum. It lies to the north of the Dettifoss waterfall. On 7 June 2008, it became a part of the larger Vatnajökull National Park.
Skaftafell is a preservation area in Öræfi, southeast Iceland. It was once a major farm, later being named a national park. Originally known as Skaftafell National Park, it was subsequently joined together with other nearby regions to form the larger Vatnajökull National Park.

Snæfellsjökull is a 700,000-year-old glacier-capped stratovolcano in western Iceland. It is situated on the most western part of the Snæfellsnes peninsula in Iceland. Sometimes it may be seen from the city of Reykjavík over Faxa Bay, at a distance of 120 km.
Þingvellir was the site of the Alþiing, the annual parliament of Iceland from 930AD until the last session held at Þingvellir in 1798AD. Since 1881, the parliament has been located within Alþingishúsið in Reykjavik.
Vatnajökull National Park is one of three national parks in Iceland. It encompasses all of Vatnajökull glacier and extensive surrounding areas. These include the national parks previously existing at Skaftafell in the southwest and Jökulsárgljúfur in the north.
Vatnsfjörður is a nature reserve located north-west of Breiðafjörður on the Hjarðarnes coast of northwestern Iceland.
