Keflavík Airport is on Reykjanes, which Visit Iceland counts as one of Iceland’s seven regions, separate from the Reykjavík capital area. The peninsula is not a suburb you have to skip on the way to the city. It is also not a place to wander onto new lava because a photo looked solid.
A rift, not a backdrop
Visit Iceland’s article on a day on the peninsula says Reykjanes is where the North Atlantic ridge comes ashore, so the rift between the North American and Eurasian plates is visible. It says UNESCO recognizes the Reykjanes Geopark, with 55 defined geosites, including Fagradalsfjall, which erupted in 2021 and again later (the same article mentions 2022 and 2023 in different sentences). It says that since October 2023 there had been seven eruptions near the Sundhnúksgígar crater, that air traffic was not affected, and that the impact was mostly local. That is a description of the period the article covers, not a forecast that the ground will stay quiet.
The same article describes the drive out of the airport as open and treeless: black basalt lava, palagonite ridges, and steam from hot springs and geothermal plants. The coast is for seabirds and, with luck, seals and whales, especially in early spring. It names the Bridge Between Continents as a symbolic crossing between Europe and North America. It also names the Blue Lagoon as a well-known bathing place on the peninsula, and museums including the Museum of Rock ’n’ Roll and Viking World. Grindavík is described as a fishing town about 10 kilometers from the Fagradalsfjall site, with restaurants, shops, and a town pool. Conditions at eruption sites change. The article tells readers to check SafeTravel and local maps before hiking new lava.
Why this matters on an arrival day
Visit Iceland’s practical page says the drive between the airport and Reykjavík takes about 45 minutes. Its South Iceland regional text says the South Coast Way, road 427, is about 30 minutes from Keflavík. A short stay can therefore be the peninsula itself, the Golden Circle, or the start of the south coast, rather than an automatic transfer into downtown Reykjavík. Those are different trips. The day-trip page keeps them apart.
The airport’s June 2024 transport article says there is a walking and cycling path between the airport and Reykjanesbær. That is a local path, not a hike across the geopark with luggage. Reykjanesbær is the municipality on the peninsula; Visit Iceland’s January 2025 practical page lists its population as 22,499. A later geography page, dated in its own text as 8 May 2026, gives different national population figures and does not repeat that municipal number, so the 22,499 figure stays attached to the earlier page.
Volcanic hazards, briefly
Visit Iceland’s safety article says new lava can look solid and still be hot and unstable, and that the crust can collapse. Stay on marked paths and follow local instructions. The same article says Icelandic mobile networks no longer run 2G or 3G, so an old phone may not connect. That is a Reykjanes problem as much as a highland one, because the peninsula is where many people take their first walk off the airport road.
