You’ll want to factor in the cost of gas, which, like most things in Iceland, isn’t cheap. A liter will cost you $1.84, which comes out to about $7 per gallon. Again, the more travel companions you have, the cheaper it’ll be.
Driving through the countryside is one of the best ways to experience all that Iceland has to offer, and if you do it yourself, you won’t be tied down to a tourist company’s pre-planned itinerary.
After spending the first day of my trip walking the capital city, I hit the road on day two. I did my own version of the Golden Circle tour, a classic day trip consisting of three main attractions — the Thingvellir National Park, the Geysir geothermal area and the Gullfoss waterfall — but added in a few additional stops, including homemade ice cream at a family run farm and a visit to a hidden, natural hot spring.
