By Rental Car:
Driving is the most flexible and recommended way to reach Arnarstapi. The journey from Reykjavik typically takes approximately 2.5 to 3 hours, covering about 190 kilometers (120 miles) via Route 1 (the Ring Road), then Route 54, and finally Route 574. Car rental prices vary significantly by season and vehicle type; a 2WD vehicle is generally sufficient for summer travel, while a 4x4 is advisable for spring, autumn, and winter conditions due to potential snow and ice. Daily rental costs can range from $40–$90 for small cars to $100–$220 for 4x4/SUVs, with summer being the most expensive period.
