Step-by-Step Guide: Flybus + Connecting Bus

Critical Advice for Driving in Iceland
- Book Early: Book months in advance for the best price and selection.
- Insurance: Get Gravel Protection (GP) and Sand and Ash Protection (SAAP). Consider full insurance for peace of mind.
- Road Conditions: Always check road.is and en.vedur.is before setting out.
- Fuel: Fill up in Selfoss or Reykjavík; stations are sparse in some rural areas.
- Winter Driving (Oct-Apr): Essential: Rent a 4x4 with studded winter tires. Drive cautiously.
Private Transfer: Door-to-Door Convenience
Ideal for families with young children, travelers with lots of luggage, or those arriving late who want a hassle-free, direct journey to their Selfoss accommodation.
How It Works & What to Expect
You pre-book a vehicle (car or van) with a driver. After clearing customs, your driver will be waiting in the arrivals hall with a sign bearing your name. They will assist with luggage and drive you directly to your specified address in Selfoss.
| Vehicle Type | Passengers | Approx. Price (One Way) | Best For |
|---|---|---|---|
| Standard Sedan | 1-3 | 25,000 - 35,000 ISK | Couples, small families |
| Minivan | 4-8 | 40,000 - 55,000 ISK | Families, small groups |
| Large Van/Minibus | 9-19 | 60,000 - 85,000 ISK | Large groups, tours |
Pros, Cons & Booking Tips
Pros: Completely stress-free, direct, meet-and-greet service, fixed price, good for odd-hour arrivals.
Cons: Significantly more expensive than bus options (unless in a large group).
Booking Tip: Use reputable local companies like Gray Line Iceland or Flight Service. Book online for a confirmed rate. Communicate your flight details and exact drop-off address.
Taxi: The Expensive Last Resort
Warning: Taxis in Iceland are among the most expensive in the world. This option should only be considered in emergencies, for very large groups splitting the cost, or when no other transport is available (e.g., very late at night with no pre-booked transfer).
Cost Reality & Practicalities
- Fare: A one-way taxi from KEF to Selfoss will cost between 40,000 and 55,000 ISK (≈ $290 - $400 USD). The meter is not used for such long trips; it's a fixed price agreed upon beforehand.
- Finding a Taxi: Official taxis queue outside the arrivals hall. Do not accept rides from solicitors inside the terminal.
- Negotiation: Always ask for the fixed price to Selfoss before getting in the car.
Bottom Line: For the price of a one-way taxi, you could often rent a small car for 2-3 days. It is almost never the economical choice.

Traveler Tips & Local Advice for Your Journey
1. Timing Your Arrival & Departure
If you arrive after 10:00 PM, your public bus options vanish. Always have a Plan B (pre-booked transfer) for late flights. Similarly, when departing from Selfoss to KEF, allow at least 4 hours before your flight using buses, accounting for transfers and potential delays.
2. Currency & Payments
You do not need Icelandic Krona (ISK) for transport. All airport buses, rental cars, and private transfers accept and prefer major international credit/debit cards (Visa, MasterCard). It's the primary payment method in Iceland.
3. Connectivity & Apps
- Strætó App: Essential for planning and buying tickets for public bus legs.
- 112 Iceland App: Download this official emergency app.
- Google Maps/ Maps.me: Offline maps are useful for driving.
4. Luggage Strategy
Buses have undercarriage storage. If you have very heavy luggage or are changing accommodations frequently, know that Selfoss has several grocery stores and a swimming pool—easy places to manage. Pack for variable weather, even in summer.
5. Beyond Selfoss: The South Coast
Selfoss is the gateway to the epic South Coast (Seljalandsfoss, Skógafoss, Reynisfjara). If you don't have a car, consider joining a guided day tour from Selfoss, as public transport to these specific sites is very limited or non-existent.
