Arrive at O’Hare International Airport (ORD) around 3:30 PM, three hours before your scheduled 6:30 PM international departure. For an overnight Iceland flight, keep essentials—warm layers, medications, chargers, eye masks, and snacks—in your carry-on rather than checked luggage. December weather can slow traffic and airport operations, so build in extra time for the drive to the airport and check your terminal and gate in the airline app before leaving home. Grab dinner after security; Tortas Frontera in Terminal 3 or Wicker Park Seafood & Sushi Bar in Terminal 2 are better bets than relying on the limited onboard meal service.
Board the overnight flight to Keflavík International Airport (KEF) around 5:45–6:00 PM and try to sleep soon after takeoff. The flight is typically about 6–7 hours, with Iceland arriving several hours ahead of Chicago; landing around 6:45 AM on December 18 means you will want to stay on Iceland time immediately. Keep your passport, rental-car confirmation, and first-day reservations accessible for arrival, and pack a small snack and refillable water bottle since the first morning will begin early after landing.
Your flight lands at Keflavík International Airport around 6:45 AM, but plan on roughly an hour for bags, rental paperwork, breakfast, and fitting winter gear into the car. December daylight is limited—about 10:45 AM to 3:30 PM—so this day is too ambitious if you intend to reach Höfn safely. Drive first to Blue Lagoon near Grindavík for a two-hour soak, but confirm both the reservation and road access shortly before departure; volcanic activity has occasionally caused closures in this area. Expect roughly $90–150 per person depending on the package, and leave valuables out of sight in the car.
If access is open and you still have daylight, continue to Reykjanesviti and Gunnuhver, about 45 minutes for the lighthouse coast and steaming geothermal ground. Stay on marked paths—Gunnuhver’s surface can be dangerously unstable—and skip this stop entirely if wind, snow, or road conditions are poor. Because the lagoon and peninsula visit will likely carry you into the afternoon, treat Reykjavík Old Harbour as an optional short walk rather than a guaranteed stop; if you make it there, stroll along the waterfront and browse the nearby streets around Grandi before dinner.
Have an early meal at Hlemmur Food Hall in Reykjavík, where several counters make it easy to eat quickly, or choose a harbor restaurant such as Sægreifinn for seafood. Allow about $25–50 per person, and check holiday opening hours in advance. The important practical decision is whether to continue east: leaving Reykjavík at 3:30–4:00 PM would put most of the Route 1 drive to Höfn in darkness, potentially 5.5–7 hours in winter, with wind, ice, and closures a real possibility. A much safer plan is to sleep near Reykjavík or Hveragerði and begin the long drive at first light on December 19; if you nevertheless continue, check road.is and safetravel.is immediately beforehand, fuel up, share driving, and stop rather than pushing on if conditions deteriorate.
Leave Höfn around 8:15–8:30 AM and drive west on Route 1 for about 60 minutes to Jökulsárlón Glacier Lagoon. In December, sunrise is close to 11:00 AM, so arriving early means you can watch the first light catch the icebergs without rushing. Allow roughly an hour on the marked shoreline; wind is often fierce here, and the lagoon’s edge can be icy, so wear traction cleats and stay well back from the water. Parking is generally free, and there are restrooms and a small café, though winter opening hours can be limited.
Walk or drive a few minutes to Diamond Beach at Breiðamerkursandur, where chunks of glacier ice wash onto the black sand. Give yourself about 45 minutes, but don’t climb on or stand beneath the ice—waves can move unexpectedly, even when the beach looks calm. From here, continue west on Route 1 toward Skaftafell, allowing about 50 minutes of driving; fill up and use the restroom before leaving the lagoon area, since services become sparse.
Plan to reach Skaftafell around 1:00 PM, giving you two to three hours before the December light fades. Choose only a marked trail that is open and suitable for the conditions; the Svartifoss route is a good option in clear weather but can be icy, steep, and slower than the summer estimate. Check conditions at the visitor center and on Safetravel.is, carry a headlamp, and turn around early if visibility or footing deteriorates. Afterward, drive a few minutes to the signed Svínafellsjökull viewpoint for a brief glacier look—stay on designated paths and never approach the ice front or meltwater channels.
Return to Höfn before or shortly after dark, usually about 90 minutes from Skaftafell in good conditions. Reserve a table at Pakkhús Restaurant near the harbor; it is known for local seafood and especially langoustine, with dinner typically around $35–70 per person. Winter hours can change, so confirm the opening time and reservation availability in advance rather than relying on a late walk-in.
After dinner, take a short walk along the Höfn waterfront, then move away from the brightest harbor lights for your aurora attempt. Give yourselves one to two hours, checking the Icelandic Met Office aurora and cloud forecasts before heading out; clear skies matter more than a high activity number. Keep expectations flexible—the Höfn area can offer excellent horizons, but cloud and wind can change quickly. If roads are icy, stay within town and avoid driving toward isolated viewpoints at night; the glacier scenery will still be there in daylight.
This is the one day where the plan needs a serious winter-weather reality check. From Höfn, leave around 8:00 AM for Stokksnes, reaching the black-sand shore near first light—December sunrise is close to 11:00 AM. Allow about 1½ hours for the beach, dunes, and views of Vestrahorn. The access road and beach area are privately managed, so expect an entrance fee of roughly ISK 1,000–1,500 per person; confirm winter access locally. Keep the visit flexible: wind, blowing snow, or icy roads can make the shoreline unsafe, and the mountain may be hidden by cloud.
On the way back toward Route 1, make a brief stop at Almannaskarð viewpoint only if the pull-off and approach are fully clear. It is a five-minute roadside photo stop rather than a hike, with excellent views over the coast and the mountains east of Höfn. By now, however, you should decide whether to continue east at all. Hengifoss and Seyðisfjörður are not realistic additions to a safe same-day drive to Vík in December: they require a substantial detour, daylight is limited to roughly 10:45 AM–3:30 PM, and mountain roads may be closed or icy. Do not attempt the full Hengifoss trail in winter; only use a clearly open, signed viewpoint if road.is and local conditions permit.
If roads are dry, visibility is good, and the official road-status map shows the route open, you can make a short visit to Seyðisfjörður via the scenic valley, allowing about two hours including the drive through the town. Walk the colorful streets near the harbor, but avoid lingering on steep or icy roads. Warm up at Kaffi Lára El Grillo Bar, generally one of the better casual stops in town; budget approximately $15–35 per person, though winter hours can change and service may be limited outside peak times. Check its social media or call before committing to the detour. If the weather is anything less than excellent, skip both eastern diversions and begin west immediately—this is not a day to gamble with a mountain crossing.
For the itinerary to work safely, aim to be back on Route 1 by about 1:00–1:30 PM, with Vík as the overnight base. The westbound drive from the Höfn area takes roughly 4½–6 hours in winter, and darkness will arrive soon after the day’s limited light fades. Fuel in Höfn before leaving, keep the tank comfortably above half, and check road.is, safetravel.is, and the Icelandic weather forecast immediately before departure. If conditions deteriorate, stop rather than pushing through; a later arrival in Vík is preferable to continuing on an unsafe road. Expect roughly ISK 4,000–7,000 in fuel, and keep dinner plans simple at your accommodation or a restaurant in central Vík, since winter kitchen hours may be short. Once parked, watch the sky away from streetlights for northern lights, but only pull over at designated safe areas.
Leave Vík around 8:00 AM, allowing extra time for icy roads and the short drive to Reynisfjara Beach. Spend about 45 minutes along the black-pebble shore, looking at the basalt columns and offshore sea stacks. Keep far back from the waterline—the sneaker waves here are genuinely dangerous, even on calm-looking days—and never turn your back on the sea. Continue to Dyrhólaey viewpoint, roughly 20 minutes away, for another 45 minutes overlooking the arch and sweeping black-sand coast. The access road may be closed in poor weather, so do not force it; December daylight is limited, with the best usable light generally from around 10:45 AM to 3:30 PM.
Drive west on Route 1 toward Skógafoss, arriving around 11:30 AM if conditions cooperate. Allow 45 minutes to see the waterfall from below and climb the adjacent staircase for the upper overlook; the steps can be icy, so traction cleats are worth having. A few minutes away, Kvernufoss makes a quieter second stop: follow the short trail from the Skógar Museum area for 45–60 minutes, but skip it if the path is frozen or visibility is poor. For lunch, continue to The Soup Company in Vík—a practical warm-up stop with soup, bread and light meals, usually about $20–35 per person. Check same-day hours, as winter service can be shorter than the posted summer schedule.
After lunch, retrace Route 1 west toward Seljalandsfoss, roughly an hour from Vík. Plan 30–45 minutes here, but treat the path behind the waterfall as optional: it is often icy, wet and poorly suited to fading light, so seeing the falls from the front is the sensible December choice. From Seljalandsfoss, continue to Hella on Route 1, normally another 45–60 minutes; aim to arrive before full darkness and check road.is and Safetravel.is before leaving Vík. If skies clear after check-in, Hella’s darker surroundings offer a better northern-lights chance than the coast—keep the car fueled and use a nearby pull-off only where parking is legal and safe.
Leave Hella around 7:30–8:00 AM with a full tank, checking road.is and SafeTravel Iceland first. The drive to Þingvellir National Park takes roughly 1½ hours in December, and the landscape may still be dark when you arrive. Allow about 90 minutes to walk the marked paths around the historic assembly site and Almannagjá rift; wear ice-gripping footwear, since boardwalks and paths can be slippery. Continue about 50 minutes to the Geysir geothermal area, where Strokkur usually erupts every 6–10 minutes. The paths are short, but stay behind the ropes and expect strong wind, steam, and icy ground.
From Geysir, it is roughly 10 minutes to Gullfoss. Spend 45 minutes at the winter viewpoints, but don’t force the lower walk if visibility or ice is poor. Afterward, drive about 35 minutes to Laugarvatn Fontana for a two-hour soak; advance reservations are important, with admission generally around ISK 5,000–6,000 per adult. If offered that day, add the geothermal-baked rye-bread experience—usually a small extra charge and best booked ahead. Fontana is an excellent late-afternoon stop because you can relax while darkness settles rather than trying to squeeze in another outdoor sight. Allow roughly 1–1½ hours to reach central Reykjavík afterward, depending on road conditions.
For dinner, head to Hlemmur Food Hall on Laugavegur, where several counters make it easy to choose different Icelandic and international dishes; budget about $20–40 per person, and check individual vendors’ evening hours before setting out. Keep this stop casual rather than lingering too long: afterward, drive around 45–55 minutes via Route 41 to an airport-area hotel in Reykjanesbær or Keflavík, allowing extra time for winter conditions. Confirm whether your rental company requires an evening return or permits overnight parking, and keep the fuel receipt and rental documents ready. This is also a good night to watch the skies away from Reykjavík’s lights if the aurora forecast is promising, but prioritize sleep and a straightforward airport run for tomorrow’s 4:30 PM departure.
With a 4:30 PM international departure, keep your final morning close to the airport. After checking out, drive into Keflavík harbor for a relaxed 45-minute coastal walk. The waterfront is exposed and often windy in December, so wear your waterproof outer layer and use the harbor roads rather than lingering on slippery rocks. Stop at Kaffi Duus near the marina for coffee and a light breakfast; it is a convenient local-style choice, though confirm opening hours the evening before because winter schedules can change.
From Keflavík harbor, it is only a few minutes by car to The Icelandic Museum of Rock ’n’ Roll in Reykjanesbær. Allow about an hour for the compact, interactive collection covering Icelandic musicians and the country’s surprisingly rich pop-music history. Check its December opening hours before setting out—seasonal hours are limited—and do not let the museum push your airport timing too late. If it is closed, keep the harbor stop leisurely rather than adding another distant attraction.
Leave central Keflavík by about 11:45 AM to allow for fuel, winter roads, and the roughly 10–15-minute drive to Keflavík International Airport. Refuel near the airport before returning the car, photograph the vehicle and fuel gauge, and allow extra time for the rental shuttle or inspection process. Aim to be at the terminal around 1:00 PM: that gives you a comfortable buffer for a 4:30 PM international flight, especially if weather slows traffic or the rental return is busy. Keep passports, boarding documents, and any remaining Icelandic cash accessible rather than packed in the luggage.
