Is 4x4 worth the extra cost in May?
 

We are planning a 11 night trip to Iceland during Memorial Day weekend. We still have not yet planned every step of the way but would like to surely do the ring road and some detours along it. I am not sure if Westfjords is accessible in end of May. Would we be able to access Westfjords if we rent a 4x4?

Will we need a 4x4 to visit places like Dettifoss, Selfoss, Haifoss? Are F66, F208, F570, F575, and F735 be navigable in end of May?

Thanks.

You do not need a 4x4 to access Dettifoss or Selfoss. F roads are a whole different animal though. We ran into some closures of regular roads the second week of June.

Info on F roads here.
