Reykjanes Peninsula on a full-day tour from Reykjavik

The Blue Lagoon is a geothermal spa in southwestern Iceland. The spa is located in a lava field near Grindavík on the Reykjanes Peninsula, in a location favorable for geothermal power, and is supplied by water used in the nearby Svartsengi geothermal power station. The Blue Lagoon is approximately 20 km (12 mi) from Keflavík International Airport and is one of the most visited attractions in Iceland.

Gardur is a former municipality and town located in southwestern Iceland, bordered by the Faxaflói Bay on the Southern Peninsula. In 2018 it merged with Sandgerdi to create the new municipality of Sudurnesjabaer.

The lake is a volcanic crater that got its name from its unusual green color. The color is due to a high level of sulfur in the water and its depth. The lake is only about a few hundred meters in diameter. For a small lake, it is quite deep, though, or 45 meters. Graenavatn is considered by geologists to be one of the most noteworthy geological phenomena of its kind in Iceland.

Grindavík is one of the nation's strongest fishing industry townships, and home to well-established processing plants and a large fleet of fishing ships. Situated in a dramatic landscape of lava fields right next to the Atlantic Ocean, Grindavik boasts breathtaking natural beauty with priceless gems of nature, such as Eldvörp, Selatangar, Gunnuhver, Brimketill, the fierce lava, the Reykjanes Light House, and much more. With the Blue Lagoon, the nation's most popular tourist destination, on it's doorstep, Grindavik has enjoyed a tremendous growth in tourism. The area surrounding Grindavik offers endless opportunities for adventure, from dramatic hiking trails, to bird-watching from the cliffs along the shore of Reykjanestá.

The mud pools and steam, vents in south-west Reykjanes. The mud pools take form where steam from boiling geothermal reservoir water emanates and condenses and mixes with surface water. Accompanying gases such as carbon dioxide and hydrogen sulfide make the water acid. This causes the alteration of the fresh lava rock to clay. Steaming of the ground at Reykjanes increased markedly as a consequence of a pressure drawdown in the geothermal reservoir upon the start of production from the reservoir in 2006.

Keflavík, meaning Driftwood Bay) is a town in the Reykjanes region in southwest Iceland. It is included in the municipality of Reykjanesbær whose population as of 2016 is 15,129. In 1995, Keflavik merged with nearby Njarðvík and Hafnir to form the municipality of Reykjanesbær.

Kleifarvatn is the largest lake on the Reykjanes Peninsula in Iceland, situated in the southern part of the peninsula. It is located in the fissure zone of the Mid-Atlantic Ridge. The lake has no visible water coming in or going out as most of its water comes and leaves underground.

Krýsuvík is a geothermal area located on the Reykjanes peninsula in the southwest of Iceland. Like many other sites nearby it is located in the fissure zone on the Mid-Atlantic Ridge. The area consists of various geothermal fields with the most famous one being Seltún.

Reykjanes Peninsula is a UNESCO Global Geopark and part of the European and Global Geopark network. The peninsula, with its diversity of volcanic and geothermal activity, is well suited to be a Geopark as it is the only place in the world where the Mid-Atlantic Ridge is visible above sea level.

Reykjanesviti is Iceland's oldest lighthouse. It serves as a landfall light for Reykjavík and Keflavík.

Reykjavik, on the coast of Iceland, is the country's capital and largest city. It's home to the National and Saga museums, tracing Iceland’s Viking history. The striking concrete Hallgrimskirkja church and rotating Perlan glass dome offer sweeping views of the sea and nearby hills. Exemplifying the island’s volcanic activity is the geothermal Blue Lagoon spa, near the village of Grindavik.
