Northern Lights in Selfoss, Iceland

Selfoss is a town of about 7,000 people straddling the Olfusa River in South Iceland. While not a tourist destination in its own right, it serves as the ideal base for exploring the Golden Circle - Iceland's most popular touring route connecting Thingvellir National Park, the Geysir geothermal area, and Gullfoss waterfall. What many visitors don't realize is that these same daytime attractions become extraordinary aurora viewing locations after dark.

At 63.93°N, Selfoss needs a KP index of 3 for reliable aurora viewing. The surrounding area is sparsely populated with minimal light pollution once you leave town. The combination of geothermal steam, historical landscapes, and powerful waterfalls provides foregrounds for aurora photography that are uniquely Icelandic.

Check the aurora forecast and plan your evenings around the Golden Circle sites - watching aurora over the same landmarks you explored by day is a special experience.

Thingvellir National Park: The tectonic rift valley where the Althing (world's oldest parliament) met for a thousand years. The open landscape, Thingvallavatn lake, and dramatic cliff formations provide exceptional aurora viewing with profound historical significance. About 40 minutes from Selfoss.

Geysir Geothermal Area: The original geyser that gave all geysers their name. While Geysir itself is mostly dormant, Strokkur erupts every 5-10 minutes, sending a column of boiling water 20-30 meters into the air. Aurora above the steam and geothermal landscape is otherworldly. About 50 minutes from Selfoss.

Gullfoss Waterfall: One of Iceland's most powerful waterfalls, where the Hvita river plunges into a deep canyon. At night, the roar of the falls accompanies your aurora viewing. The spray can be challenging for cameras but creates atmospheric effects. About 1 hour from Selfoss.

Kerid Crater: A volcanic crater lake about 15 minutes north of Selfoss. The perfectly circular lake and red volcanic rock create a unique foreground. On still nights, the aurora reflects in the crater lake.

The aurora season around Selfoss runs from September through March:

September-October: Excellent months for combining Golden Circle sightseeing with aurora. Daylight is still generous (10-14 hours) for exploring, with dark nights from about 8-9 PM. Autumn colors enhance the landscape. Temperatures 4°C to -1°C.

November-January: Short days (4-6 hours of light) limit sightseeing time but maximize aurora viewing hours. The Golden Circle sites are quieter with fewer tour buses. Fresh snow on the landscape creates a magical winter setting. Geysir's steam clouds are most dramatic in cold air.

February-March: A sweet spot with lengthening days for Golden Circle exploration and still-long nights for aurora. Weather becomes more stable with more frequent clear sky periods. The spring equinox effect in March can enhance geomagnetic activity.

Getting There: Selfoss is about 1 hour from Reykjavik via Route 1. From Keflavik Airport (KEF), it's about 1.5 hours. The drive is straightforward on good roads.

Accommodation: Hotel Selfoss is the main hotel, featuring a spa with river views. Guesthouses, hostels, and Airbnb options are available in and around town. For a more upscale option, the ION Adventure Hotel near Thingvellir offers luxury accommodation with dark-sky viewing from geothermally heated outdoor pools.

Self-Driving Recommended: While Golden Circle tours run from Reykjavik, having your own car gives you the freedom to return to sites after dark for aurora viewing. The roads between Selfoss and the Golden Circle attractions are well-maintained even in winter.

Combining with South Coast: Selfoss is also the starting point for south coast trips to Vik, Skogafoss, Seljalandsfoss, and the glacier lagoons. A multi-day trip from Selfoss combining the Golden Circle with the south coast covers Iceland's greatest hits while maximizing aurora opportunities each night.
