Iceland

[mingo]

We did in 2017.  We rented a SUV.  Stick shift/diesel.  The unusual thing was we normally don't take insurance (in the states) but out of the country we figured it was a good idea.  In addition to collision, we also took sand and ash coverage.  That was a first time for those for us 🙃

Lots of rental options in Reykjavik.  Fewer in Akureyri, but you can find cars there, too.  Cheaper cars are generally Stick shifts which surprises a few folks who have no idea how to drive one.  They are labeled as such on the websites, but who looks for that kind of info when you really don't expect it?

Yes we rented a Rav4 from a locally owned company in Akureyri. The  office and parking lot were a block from the cruise pier.  Turn-in was easy-least - we were gone for about 10-12 hours and just had to park it and drop the keys in a slot at their office.
 

We drove from Akureyri to Dettifoss and Asbergyi. We’d visited all the other wonders in the area (Godafoss,  Myvatn lake sites, geothermal area (mud pots), spa, Krafla) a couple years earlier but had to bypass Dettifoss as we were in an RV (aka camper van) and couldn’t legally take it on the necessary roads. Great DIY trip both ways.

 

Recommend getting AWD at a minimum, even if you don’t think you’ll need it. Also get the crazy extra insurances (ash etc) - Iceland is a (magnificent) world of its own!
