Notes/Time-Mapping:
First, pick up your car at Blue Car Rental - a short 10 minute walk across from the airport.
Then, head to Reykjavik to check in at your hotel. Reykjavik, like all cities, is an "explore at leisure"experience.
I have listed out my favorite top highlights of the city, including the famous church, rainbow street, main shopping street, and historic square. Feel free to roam around to all of them, orpick and choose!
