You must book your entry in advance, particularly in high season, and it is easy to combine with a flight, since the lagoon lies only about 20 minutes from Keflavík Airport. Shower thoroughly before getting in, protect your hair with conditioner, and allow at least two to three hours for the visit.

The two tectonic plates are slowly pulling apart at roughly two centimetres a year, and Iceland sits right where the Mid-Atlantic Ridge rises above the sea. The visible fissures across Reykjanes are evidence of that movement. The bridge, completed in the early 2000s, was built as a symbolic link, and it honours the explorer Leifur Eiríksson.

Garðskagi is a favourite spot for birdwatching, especially during spring and autumn migrations, and for sunsets that turn the sky orange and pink. On clear winter nights it is a good place to see the northern lights. A small museum and café stand by the lighthouses. Bring warm, windproof clothes, since it is almost always breezy.
