Self-drive route map for 4 days in Iceland road trip
Day 1: Arrival in Iceland + Reykjavik Exploration
On your first day in Iceland, you’ll arrive at Keflavík International Airport. From the airport, take the free car rental shuttle to the Firefly Iceland Keflavík Downtown location at Flugvellir 11, where you can pick up your rental car. From there, it’s around a 45-minute drive to Reykjavík, where you can start exploring Iceland’s capital.
Just a few of the must-see sites include the Hallgrímskirkja Church, Harpa Concert Hall, and the Sun Voyager Sculpture. Don’t miss your chance to indulge in the country’s favorite, budget-friendly street food of Icelandic hot dogs at Bæjarins Beztu Pylsur.
We recommend you stay in Central Reykjavik for easy access to the city’s best attractions, restaurants, and nightlife. You’ll also find plenty of parking in the heart of the city.
If you still have some energy left over and you happen to be visiting sometime between November and March, head out on a northern lights self-drive tour in the evening. Hallgrimskirkja located in the city center of Reykjavik.
Day 2: Golden Circle Tour (Full Day)
Head out of Reykjavik early on your second day in the city, headed for the famous Golden Circle. This is one of the best self-drive adventures in Iceland and a popular day trip from Reykjavik, a 186-mile loop that starts in the capital.
Your first stop is Iceland’s Thingvellir National Park, a UNESCO World Heritage Site that’s known for its unique geology and ties to both Viking and Icelandic heritage. Here you can witness where the first Icelanders held important meetings and stand between the North American and Eurasian tectonic plates.
The second stop along the Golden Circle is the Geysir Geothermal Area to witness the Strokkur geyser erupt before continuing on to the mammoth Gullfoss Waterfall. If time allows, you’ll also pass by the Kerið Volcanic Crater. Take a walk around the crater’s edge and admire its turquoise water before heading back to Reykjavik.
Spend the rest of your day relaxing at Sky Lagoon, Reykjavik’s answer to the Blue Lagoon with stunning oceanfront views.
Day 3: South Coast Adventure (Full Day)
Summer version (when Iceland has almost 24 hours of daylight)
Summer on Iceland’s South Coast is truly spectacular, with nearly 24 hours of daylight allowing for extended exploration. Start early from Reykjavik and head south on Route 1, the famous Ring Road.
Begin your adventure at Seljalandsfoss and Skógafoss, two of Iceland’s most iconic waterfalls, both easily accessible from the main road. Take your time to admire their stunning beauty and capture some unforgettable photos. From here, you have two options for the day:
Recommended Option: Vik and Nearby Attractions
Explore Reynisfjara Black Sand Beach, the dramatic Dyrhólaey cliffs (a summer puffin hotspot), and the Sólheimajökull Glacier. Adventure seekers can hike to the DC-3 Plane Wreck, while history buffs will enjoy the charming village of Vik with its hilltop church and local dining options.
Optional: Jökulsárlón Glacier Lagoon
Drive further to see the breathtaking Jökulsárlón Glacier Lagoon and Diamond Beach, with their floating icebergs and black sand. This 8-10 hour round trip is long and tiring, so ensure at least two drivers to share the journey safely.
Return to Reykjavik in the evening, stopping in Vik for dinner if taking the extended route. Both options promise unforgettable memories of Iceland’s South Coast
Winter version (when Iceland only a few hours of daylight)
Spend your day exploring Iceland’s stunning South Coast with a trip to Vik. Start with the iconic Seljalandsfoss and Skógafoss Waterfalls, both magical in winter with their icy surroundings. Continue to Reynisfjara Black Sand Beach, where the snow and black sand create a surreal winter landscape. Stay cautious of the strong waves.
In Vik, visit the picturesque Vik Church and enjoy a hearty Icelandic meal at a local restaurant. Begin your drive back to Reykjavik in the afternoon to ensure safe travel before dark, and check road.is for the latest conditions. Winter driving essentials include studded tires, warm clothing, and snacks for a smooth journey.
Day 4: Departure + Blue Lagoon
It’s your last day in Iceland and time for some R&R. Spend your final moments in Iceland at the Blue Lagoon, luxuriating in its heavenly geothermal water and spa treatments. Just 45 minutes from Reykjavik by car, and on the way to the Keflavik Airport, this is an ideal stop before you catch your flight home.
Drop off your rental car with Firefly Iceland at the Keflavik Airport and wave goodbye to the Land of Fire and Ice!
What Car Do You Need for a 4-Day Iceland Road Trip?
For this particular Iceland self-drive itinerary, your ideal rental car depends mainly on the season.
Summer: A 2WD Rental Car is Usually Enough
If you’re visiting Iceland between late spring and early autumn and following the itinerary above, an affordable 2WD car rental will usually be suitable.
The main roads connecting Keflavík, Reykjavík, the Golden Circle, Vík and the South Coast are accessible without driving on Highland F-roads.
A small economy rental car can also help keep the overall cost of your Iceland trip down by offering:
- Lower rental prices
- Good fuel economy
- Easy parking in Reykjavík
- Enough capability for the main tourist routes included in this itinerary
If you plan to add the Icelandic Highlands or F-roads to your trip, you will need a suitable 4×4 rental car, as 4×4 vehicles are legally required on F-roads.
Winter: Consider a 4×4 Rental
Winter brings a very different driving experience. Snow, ice, strong winds and rapidly changing weather can affect roads around Iceland.
A 4×4 rental in Iceland can be a good choice for a winter road trip because four-wheel drive provides additional traction in difficult conditions. However, a 4×4 does not make winter driving risk-free, and you should always adjust your plans to the weather and road conditions.
Before driving each day, check Iceland’s official road and weather information.
Summer vs Winter: When Is Best for a 4-Day Iceland Trip?
You can follow this 4-day Iceland itinerary throughout the year, but the experience changes considerably between summer and winter.
| Summer | Winter | |
| Daylight | Very long days | Short days |
| Driving | Generally simpler | Snow and ice possible |
| Rental car | 2WD often suitable | 4×4 worth considering |
| Main advantage | More time for sightseeing | Northern Lights season |
| Crowds | Higher | Generally lower |
| Costs | Usually higher | Can be lower outside holidays |
| Best for | Long sightseeing days | Winter landscapes and aurora |
Visiting Iceland in Summer
Summer, particularly June, July and August, is the busiest time for an Iceland road trip.
Long daylight hours give you more flexibility when sightseeing, which is particularly useful on Day 3 when exploring the South Coast.
Temperatures are generally milder than in winter, but Icelandic weather can still change quickly. Bring layers, a waterproof outer layer and sturdy walking shoes.
Summer is also the busiest period for accommodation and car rental in Iceland, so booking early can help you secure more vehicle choices and potentially better prices.
Related Firefly guides: Iceland in June, Iceland in July and Iceland in August.
Visiting Iceland in Winter
A winter road trip gives you the chance to experience snow-covered landscapes, fewer daylight hours and the possibility of seeing the Northern Lights.
Winter driving requires more planning. Conditions can change quickly due to snow, ice and strong winds, and road closures are possible.
Plan shorter driving days, allow additional time between attractions and avoid creating an itinerary that depends on arriving somewhere at an exact time.
Warm layers, waterproof outerwear, gloves, hats and insulated footwear should all be on your packing list. Read our guide to what to wear in Iceland during winter before traveling.

How Much Should You Budget for 4 days in Iceland?
The cost of a 4-day Iceland trip varies depending on when you travel, where you stay, which rental car you choose and how many paid attractions you visit.
If you’re traveling on a budget, focus on the expenses that matter most:
Book Your Iceland Rental Car Early
Car rental prices can change according to season and demand. Booking your cheap Iceland car rental early gives you a better chance of finding the vehicle category you want at a competitive price.
Choose the Right Car, Not the Biggest Car
You don’t automatically need a large SUV to visit Iceland.
If you’re visiting in summer and sticking to Reykjavík, the Golden Circle and South Coast, a small economy car can be one of the cheapest ways to complete this itinerary.
Choose a 4×4 when your route or the season makes the additional capability useful rather than automatically paying for a larger vehicle.
Save Money on Food
Restaurants can take up a large part of an Iceland travel budget. Buying breakfast items, snacks and simple meals from supermarkets can significantly reduce your daily spending.
Focus on Free Attractions
Many of the highlights included in this itinerary can be experienced without purchasing an expensive guided tour. Iceland’s waterfalls, landscapes and viewpoints are a major reason why a self-drive Iceland trip can work well for budget travelers.
Remember that individual attractions and parking areas may still charge admission or parking fees.
Why Rent a Car for 4 Days in Iceland?
A rental car gives you considerably more flexibility when you only have a few days in Iceland.
Instead of booking a separate tour for Reykjavík, the Golden Circle and South Coast, you can create your own schedule and decide how long you want to spend at each destination.
An Iceland car rental is particularly useful if you want to:
- Visit multiple region during a short trip
- Stop at viewpoint along the way
- Start sightseeing earlier or later
- Travel without following tour timetable
- Carry luggage, food and outdoor clothing
- Adjust your route according to the weather
- Explore Iceland on a budget
For tow or more people traveling together, comparing the total cost of a rental car with multiple individual tours can also be worthwhile.

Essential Iceland Self-Drive Tips
Check the Weather Before Driving
Icelandic weather can change quickly. Check the forecast before leaving and be prepared to adjust your route when necessary.
Check Road Conditions
Road conditions can vary considerably by region and season. Check road.is before longer journeys, particularly during winter.
Never Drive Off-Road
Off-road driving is illegal in Iceland. Always remain on marked roads and tracks to protect Iceland’s fragile landscape.
F-Roads Require a 4×4
If you extend your trip into the Icelandic Highlands, remember that a 4×4 is legally required on F-roads. F-roads are generally only open during the summer months and opening dates vary according to conditions.
Watch the Wind
Strong Icelandic winds can affect driving and can damage vehicle doors if they are opened carelessly. Always check conditions before traveling and hold onto the car door when getting in or out in windy weather.
Don’t Stop on the Road for Photos
Iceland is full of landscapes that make you want to stop immediately, but never stop your rental car on the road. Find a safe, designated parking area before taking photographs.
Keep Your Headlights On
Vehicle headlights should be on while driving in Iceland, both during the day and at night.
Frequently Asked Questions About a 4-Day Iceland Road Trip
- Is 4 days enough for Iceland?
Yes. Four days is enough for a short Iceland road trip covering Reykjavík, the Golden Circle, part of the South Coast and the Blue Lagoon. It isn’t enough time to comfortably drive the entire Ring Road, so focusing on southwest and South Iceland allows you to see more without spending most of your holiday in the car.
- What can you see in Iceland in 4 days?
In four days, you can visit Reykjavík, Þingvellir National Park, Geysir, Gullfoss, Seljalandsfoss, Skógafoss, Reynisfjara, Vík and the Blue Lagoon. In summer, longer daylight hours may allow you to add additional stops.
- Do I need a rental car for 4 days in Iceland?
You don’t have to rent a car, but an Iceland rental car gives you significantly more flexibility. It allows you to follow the Golden Circle and South Coast at your own pace rather than relying on separate tours and fixed departure times.
- Can I rent a car at Keflavík Airport?
Yes. Keflavík International Airport is the main arrival point for international visitors and a convenient place to start an Iceland road trip. Firefly Iceland serves KEF through the car rental shuttle, with its rental location at Flugvellir 11 near the airport.
- Do I need a 4×4 for a 4-day trip in Iceland?
Not necessarily. During summer, a standard 2WD rental car is generally suitable for the main routes included in this itinerary. During winter, a 4×4 can be a useful choice when snow and ice are present. If you plan to drive on F-roads, you must use an appropriate 4×4 vehicle.
- Can I drive the Colden Circle in a 2WD car?
Yes, under normal conditions the main Golden Circle route is accessible with a standard 2WD rental car. Always check current weather and road conditions before traveling, particularly during winter.
- Can I drive Iceland’s South Coast in a small rental car?
In normal summer conditions, the main South Coast attractions along and near Route 1 can generally be reached with a standard 2WD vehicle. Winter conditions can make driving more challenging, so your vehicle choice should take the season and forecast into account.
- Is it cheaper to rent a car or take tours in Iceland?
It depends on the number of travelers, rental price and tours you want to take. For travelers visiting several destinations over multiple days, a budget rental car can be cost-effective because the same vehicle can be used for airport transport, the Golden Circle, South Coast and other sightseeing.
- What is the cheapest type of rental car in Iceland?
Small economy cars are generally among the cheapest rental car categories in Iceland. They are particularly suitable for travelers visiting during summer who plan to stay on main paved routes.
- Is driving in Iceland difficult?
Driving on Iceland’s main roads is manageable for many visitors, but conditions can be very different from what you are used to at home. Strong winds, gravel, snow, ice and rapidly changing weather all require additional care. Winter driving requires considerably more preparation.
- When is the cheapest time to rent a car in Iceland?
Car rental prices depend on demand, vehicle availability and travel dates. Summer is the busiest travel season, while prices can be lower at other times of year. Comparing dates and booking your rental car early can help you find a better deal.
- Can I see the Northern Lights on a 4-day Iceland trip?
Yes, if you visit during the darker months and conditions are favourable. Seeing the Northern Lights depends on darkness, cloud cover and aurora activity, so sightings are never guaranteed. Having a rental car gives you flexibility to drive away from Reykjavík’s brightest lights when conditions are suitable.
- Can you drive Iceland’s Ring Road in 4 days?
Technically it is possible to cover the distance, but four days is very short for a full Ring Road trip and would involve a lot of driving. For a four-day visit, Reykjavík, the Golden Circle and South Coast make a much more manageable self-drive itinerary.
- Are F-roads included in this 4-day itinerary?
No. You do not need to drive on F-roads to follow this itinerary. If you decide to add the Highlands to a longer summer trip, remember that F-roads require an appropriate 4×4 rental vehicle.
