Arrive at Keflavík Airport and pick up your rental car—allow time to collect luggage, buy a local SIM or snacks at the terminal, and enjoy the roughly 1-1.5 hour scenic drive to Selfoss via Route 41 and the Hringvegur (1). Stop in Keflavík or Reykjanesbær for a quick coffee and stretch if needed, then follow the coastline and lava fields into South Iceland as winter light plays across the landscape.
Check into your hostel near Selfoss, drop off your bags, and take a gentle orientation walk around the town center—visit the banks of the Ölfusá river, pop into a local grocer for supplies, and warm up with a bowl of lamb soup or a freshly baked pastry at a café like Kaffi Kró. If daylight and weather allow, drive a short way to the nearby Hellisheiði/Grafarkirkja viewpoints or the Hjálparfoss area for an easy photo stop to get your bearings before dusk.
After an early dinner at a cozy Selfoss restaurant or a hostel cook-up, prepare for your first Northern Lights hunt: check the aurora forecast (Vedur.is) and head a short drive from town to darker sky spots such as the Strandarkirkja area or the gravel roads north of Selfoss for minimal light pollution. Dress in layers, bring a thermos and tripod for night photography, and plan to wait patiently—if clouds roll in, your first night is also a relaxed chance to gel with fellow travelers and rest up for a busy week ahead.
After breakfast at the hostel, set out from Selfoss to the Golden Circle with your rental car—first stop is Þingvellir National Park where you can stroll between the tectonic plates, visit the rift valley viewpoint and the historic Alþingi site while winter light catches the icy fissures. Continue to the Geysir geothermal area to watch Strokkur erupt on a regular cadence and warm up with coffee from the visitor center as steam and snow create dramatic contrasts.
Drive a short distance to the thundering Gullfoss waterfall and explore the viewing platforms—wrap up in waterproof layers to feel the spray and photograph the falls framed by snow and iced cliffs. If time and road conditions allow, drop by the geothermal Hellisheiði Power Plant viewpoint or Kerið crater for a quick rim walk before returning toward Selfoss for a mid-afternoon rest or a snack at a local café.
After an early dinner back in Selfoss, check the aurora forecast and head to a low-light spot such as the gravel roads near Þorlákshöfn or the countryside north of Selfoss for another Northern Lights hunt; bring a tripod, spare batteries and a thermos. If weather closes in, consider a cozy visit to the Secret Lagoon in Flúðir on the way back for a warm soak under the stars—it's a relaxing alternative that keeps you ready should the skies clear later.
Leave Selfoss after an early breakfast and drive east along Route 1 toward Seljalandsfoss, timing your arrival to capture soft morning light on the fall; if conditions permit, walk the path behind the curtain of water for an unforgettable, misty perspective (wear waterproof layers and grippy boots). A short drive further brings you to Skógafoss—climb the stairs to the upper viewpoint for sweeping coastal views and listen for the thunderous roar as you explore the base where rainbows often form in the spray.
Continue along the coast to the Sólheimasandur plane-wreck turnoff or, if you prefer less walking in winter, head straight to the dramatic Reynisfjara black sand beach near Vík to photograph the basalt columns, Reynisdrangar sea stacks and powerful Atlantic waves—stay well back from sneaker waves and follow local safety signs. If time allows, swing by the nearby Dyrhólaey promontory for puffin-cliff views (puffin season is later) and panoramic vistas, or pop into the small Vík village café for soup and a warm drink before heading back toward Selfoss.
Drive back to your Selfoss-area hostel in the late afternoon to rest and warm up, then check the aurora forecast for a final coastal aurora opportunity—Þorlákshöfn harbor or the quiet gravel roads south of Selfoss make great low-light vantage points if skies clear. Alternatively, soak away the day's chill with a visit to a local geothermal pool or hot tub near Selfoss before an early night, readying batteries and camera gear for another aurora hunt if the heavens cooperate.
Sleep in a little after the past few long drives, then enjoy a leisurely breakfast at the hostel before heading to the Secret Lagoon in Flúðir (about 25-30 minutes from Selfoss). Soak in the warm, mineral-rich water among steam vents and a small geothermal stream while taking in the snowy surroundings—there’s a simple boardwalk and a small cafe for a mid-morning hot drink.
After your soak, stop in the nearby village of Hveragerði to explore its geothermal park and see boiling hot springs and steam vents close-up; warm up with lunch at a local bakery or café such as Kjörbúðin. If you’re feeling energetic, walk the Reykjadalur hot spring river trail (shorter winter route permitting) for a scenic, mild hike with thermal river-side bathing options, or else return to Selfoss to browse the local shops and the Ölfusá riverbank.
Enjoy a relaxed dinner either cooked at the hostel or at a cozy Selfoss restaurant, then check the aurora forecast and drive to a nearby dark spot like the Strandarkirkja stretch or countryside roads north of town for a local Northern Lights attempt. If clouds move in, trade the hunt for an evening soak at a smaller municipal pool (Sundhöll Selfoss) and social time with fellow travelers—either way it’s a low-key night to recharge before tomorrow’s possible glacier adventure.
Set out early from your Selfoss hostel for a full-day excursion toward the Vatnajökull region — if you book a guided ice cave or glacier hike (departing from Skaftafell or the Jökulsárlón area), you'll meet guides, get crampons and helmets, and transfer onto the glacier for surreal blue-ice caverns and sculpted crevasses that photograph beautifully in winter light. If you prefer something shorter, plan a scenic drive to the Jökulsárlón glacier lagoon and the nearby Diamond Beach to watch icebergs bobbing in the cold surf and capture the otherworldly contrast of ice on black sand.
After exploring the glacier or lagoon, warm up with a late lunch in Höfn or at a cozy stop in the Skaftafell visitor center, then take time for a short walk to Svartifoss waterfall framed by basalt columns (if road and trail conditions allow) or cruise the Jökulsárlón shore for more iceberg views. Begin the return drive toward Selfoss in the mid-afternoon, stopping for scenic photo breaks along the South Coast (Vík turnoffs, Dyrhólaey from distance) as daylight fades and you retrace the route you took earlier in the trip.
Back in the Selfoss area by evening, shed wet layers and check the Vedur.is aurora and cloud forecasts for a final hunt from your southern base — great low-light spots include the dark gravel roads near Strandarkirkja or Þorlákshöfn harbor for unobstructed northern views. If you're chilled after the long day, opt for a restorative soak at the Secret Lagoon in Flúðir en route to the hostel and keep an eye on the skies; either a soaking session or a patient night-photo vigil could deliver a last memorable curtain of green above the snowy fields.
After breakfast and a final tuck-away of your Selfoss bags, make the roughly 1-1.5 hour drive west toward Reykjavík, allowing a detour to the Blue Lagoon (booked in advance) or the less-crowded Sky Lagoon near Kópavogur for a soothing geothermal soak en route. Enjoy the milky-blue waters, silica masks and warm steam while watching the winter light on lava fields — this is a perfect, restorative transition from rural south Iceland to the capital.
Check into your Reykjavík accommodation and take a compact orientation walk through the city center: stroll Laugavegur for boutique shops and cafés, visit Hallgrímskirkja for the tower viewpoint and pop into the Harpa Concert Hall to admire its honeycomb glass facade and waterfront setting. Warm up with a late lunch of lamb or seafood at a downtown bistro (try Messinn or Apotek for Icelandic flavors), then browse the National Museum or Reykjavík Maritime Museum for a quick cultural primer on Icelandic history and seafaring.
After dinner, scan the aurora and cloud forecasts and keep an eye on the sky; if conditions look promising, drive a short distance to Grotta Lighthouse on the Seltjarnarnes peninsula for a dark-sky vantage point and a last-chance city-area Northern Lights attempt. If the sky stays cloudy, enjoy Reykjavík’s nightlife instead — sip a craft beer at a local pub or relax in a geothermal spa’s night session (Sky Lagoon’s cold-plunge and sauna ritual is particularly restorative) and savor a calm final night in town before your last full day of sightseeing.
Start your day with breakfast at a cozy café on Laugavegur, then visit Hallgrímskirkja—take the elevator up the tower for sweeping winter views over the city and surrounding mountains to cement your sense of place. From there wander downhill to the Harpa Concert Hall to admire its geometric glass facade and, if open, pop into a morning chamber concert or gallery exhibition for a dose of Icelandic arts.
After lunch at a seafood bistro like Messinn or a casual bite at Bæjarins Beztu for the famous hot dog, head to the National Museum of Iceland to follow the arc of Icelandic history from settlement to modernity, then stroll the waterfront to the Sun Voyager sculpture and the Reykjavík Maritime Museum for coastal and seafaring stories. If you’d like a contemporary contrast, slip into the Reykjavik Art Museum (Kjarvalsstaðir) or explore boutique shops along Skólavörðustígur for local design and woolens.
Dine at a downtown restaurant—consider seafood or lamb specialties—and keep an eye on the Vedur.is aurora and cloud forecasts as dusk falls; if skies promise activity, drive 20 minutes to the Grotta Lighthouse on Seltjarnarnes for a dark-sky vantage or join a short evening aurora tour that can shuttle you to clearer skies. If clouds persist, enjoy Reykjavík’s nightlife with a relaxed beer at a microbrewery or a late soak at the Sky Lagoon’s evening ritual, saving one last hopeful glance skyward before bedtime.
Pack up and check out after a relaxed breakfast at your Reykjavík hostel or hotel, giving yourself extra time to return your rental car and drive the 45-60 minutes to Keflavík Airport—stop at a gas station en route to top up and grab last-minute snacks or a local cinnamon roll. If your flight is later, detour via the Blue Lagoon or Sky Lagoon (if not yet visited) for a final warm soak and silica mask to leave Iceland refreshed before the journey home.
If your schedule allows a final few hours in the city, drop your luggage at a left-luggage point and stroll Laugavegur and the waterfront one last time—visit Hallgrímskirkja for a quick tower view, pop into Harpa for a final photo, and enjoy a leisurely lunch at a bakery or seafood bistro like Messinn. Alternatively, head straight to Keflavík, return the car, and use the airport’s cafés and duty-free for last-minute souvenirs while you complete check-in and security.
Board your flight home with memories of geothermal baths, thundering waterfalls and, hopefully, aurora-lit nights; if you have an evening departure, savor a final Icelandic meal at the airport café and keep an eye on the sky once more from the tarmac-side windows—Iceland often offers one last dramatic light show as you lift off. Safe travels, and consider saving your favorite photos to share and plan a return trip to chase summer highlands or more northern lights another season.
