Reykjanesbær
Reykjanesbær is a town with three major districts.
Keflavík - Njarðvík
Keflavík is first mentioned in written sources about 1590 as the base of an English trader, who was followed by German, and later Danish, merchants. Keflavík is a major center of fishing and fish processing, although in recent years tourism has played an increasingly important role in the local economy. The town's hotels and restaurants are among the best in Iceland, and the bus station, home to the Reykjanes Tourist Information Office, is the departure point for a series of sightseeing tours of the region.
Keflavík is also an excellent base from which to explore much of Reykjanes on foot. For golfers, one of Iceland's best courses, Leira, is just a short drive away, while other facilities on offer include an outdoor swimming pool, sea-angling, and whale spotting, with the possibility of sighting minke and killer whales, and cruises to the island of Eldey, home to the world's largest gannet colony. Keflavík is only a five-min drive from Iceland's international airport, and it is a short distance from the Blue Lagoon.
Hafnir
Hafnir's picturesque harbour offers an exceptional opportunity to witness at first hand the sheer power of the surging North Atlantic rollers. As they break over the outer wall in a foaming welter of surf and spray, a telling reminder of which is the anchor of the Jamestown, which stands nearby. Hafnir is also home to what is undoubtedly one of the world´s strangest banks, he "Halibut 
Bank," where small halibuts are gathered and farmed to market size before being exported abroad.
South of Hafnir the road crosses the lava fields thrown up by the region's last volcanic eruption in 1268. Rising from the sandy beach at Sandvík, the 30m-high mass of Hafnaberg, one of Iceland's largest bird cliffs but now accessible by a footpath is also an excellent place for spotting whale. Here, the real adventure of Reykjanes begins.
