The only toll road in Iceland is at the Vaðlaheiðargöng tunnel, which is on Route 1 a few km east of Akureyri in the north of the country. Signs are placed at the approach to the tunnel at either end to alert drivers that they are now on a toll road, how to pay for the journey and how much it costs. Journeys should be registered within 3-hours of using the tunnel. Payment has to be done through the web www.veggjald.is where there is a special "payment for rental cars" option. The price for a single trip is ISK 1,500 if the trip is paid via the tunnel website. If not the price goes up to ISK 2,500 and will be billed to the owner of the car. Geysir will charge the tunnel price plus an Admin fee of €25 resulting in a total price of approx. EUR 45.
There is an alternative route using the original road which goes over the mountain (see map). If travelling from Akureyri it is on Route 83 then onto Route 84. If travelling from the east on Route 1, turn right after crossing the bridge over the river Fjnoská onto Route 84 and then onto Route 83.
